Hello everybody hooded cobra commander 788 here, and this is a donation unboxing video and This has been a long time coming I usually do these unboxing videos once a month because you guys send me stuff every month And you've continued to send things to me even though I haven't gotten to an unboxing video So there's there's quite a bit here and some of this stuff has been waiting for two months three months too long for this reason, I'm going to Ask you to hold off on sending donations to the channel Until I can get back to my usual routine of opening these things on Camera so I can show the proper appreciation for them these donations are extremely generous and you deserve to Have that appreciation shown for what you send so until I can do that I don't want to keep getting stuff and taking donations when I can't Show appreciation on camera for that really it's just a matter of time and energy I have been doing really well but then I changed jobs and That is where my Time and energy has been going I Think things will settle down eventually and I'll be able to get back to my normal routine but until then It's just it's been difficult to get to My usual videos. I've been way off of my usual schedule So I apologize for that and I will do my best to get back to it for today's purposes I am not going to read aloud all of the Letters that have been sent to me and there are quite a few here. I appreciate you sending letters I appreciate everything that you send I will still open these and I will read these I will not do that on camera though And I will still be keeping them In my special fan mail envelope, so I will never lose these I will have these with me forever Thank you for taking the time to to write into me. That's very special and I appreciate that very much I'm just going to go through the boxes. There may be some letters inside the boxes I will get I will give those a quick read to myself In case there's important information in those letters But These boxes have been waiting For quite a while and I need to get to them. So I'm going to get to them Right now. These are not in any particular Order. In fact, I think this one is the most recent one and I'm gonna do this one because it's on top I've got coffee here and I've already cut open each of them so They should be all just ready to pull out and show you what's in them So this one is from Brandon Knight and I believe this is the most recent one that I got So I'm kind of going in reverse order here, but thank you Brandon and what Brandon has sent Something in a comic book and he's got a letter. Let me read this real quick. I wish I had got my Glasses I didn't think of that. Oh, well But he writes with a large enough Letters that I can read it Thank you Brandon. Thank you for the letter and thank you for this which is Which was I don't have a remote on this camera. So I can't zoom it in but this is Marvel Comics Transformers Generation 2 Which I guess includes GI Joe number 140 141 142 there was a crossover of Transformers into GI Joe Which Is yeah, I've read that and Yeah, that was surprising to see Transformers in GI Joe so thank you very much for this Brandon I will be keeping your letter with the other letters and I will never lose that and this is very much appreciated I've not read the actual Transformers generation 2 comic book But it's sealed so I May I may get a reading copy. I don't want to open I want to break the seal on this since this is something that that you have kept sealed for so long So thank you for that Brandon. I'm going to Move on to oops move on to this one and this one says This person does not want his or her name red Or location in the video, so I will not share this person's name Looks like we have another letter here, let me read this really quick, okay It's just people that want to keep their information private, which is totally fine read part two, okay? All right from a subscriber. Thank you very much And the main item is something that he or she made his or herself Okay All right, I think I got it and that person wanted to keep their information private anyway, so That's not one that I would read on the air in any case But we've got let's see what we got here this. Oh Look at this. Okay. Check this out. This these are parts for 12 inch figures including Yes, a Battle helmet head for Cobra commander, which I think will fit on my 12 inch Cobra commander figure as well as oh we can Look at this. This is a cape With gold gold rope Which I can I can make my 12 inch Cobra commander a Regal Cobra commander with this. This is awesome. We've got some boots With with Cobra on the souls. We've got a golden pistol we've got Is that a yeah a pistol in holster and And Let's see. There's another pistol and we've got alternate hands Alright, so yeah, and here we go another another pistol in a holster. So this it could be used to turn Cobra commander into a regal Cobra commander and that is awesome. I especially like the cape And that head looks awesome So, thank you anonymous for this There is more and what we have here These are oh, I think I know what these are. All right Transformers bought bots and we've got yes, the paperwork for those and We've got this is perfect. We've got one that transforms into a Coffee maker here. Yeah, that's what it appears to be is a coffee maker That's appropriate since I am having coffee and another one that looks like it transforms into a Slushie That's awesome a radioactive slushie So no, that's cool. I'm gonna have to play with these a bit. I Know I mean I've seen some But I don't know a whole lot about Transformers bought bots But I think they are Adorable, so thank you anonymous for that. Oh We've got Cobra commanders briefcase with Yeah, small Cobra emblem on it there and let's see and his Pistol and his his dagger that's awesome if I can get it out It's like I've got a ball and claw Dagger that's so cool So that this can go with the Cobra commander custom. We've got who we've got Let's see though. These are Cobra logos Small ones and we've got oh, yeah toy hacks. I know toy hacks. We've got Decepticon and Autobot Autobot logos through toy hacks So some replica stickers there. We've got two of something Let's see. Oh look at that. Hey, this is I'm gonna I want to reveal this as I Scroll it out It is a wicked awesome picture of Zerana That's cool It's like it's in like it's slightly an anime style. It's like an anime Zerana But really nice well done Even got her like Buzzsaw rifle sort of thing that she has That's awesome. I Do love a good artwork and this is really cool Well, well done. Well, they need to snap it closed like that. There we go. I want to carefully roll it So it remains undamaged And let's see And then ah, there we go This is what the rest of the stuff goes with let me see let me get this on On This is a Hall of Fame Cobra Commander. Well, it's It's not exactly a Hall of Fame Cobra Commander. This is on a different body because we have Unlike the Hall of Fame figures. We have knees. We have elbows. This is Nice and I can't let's see I Get them to stand right there. I Want to see if I can swap heads Yeah, stand there for just a second Coco. Don't fall So this is the hood. Let's see that goes with the Hall of Fame figure the hooded head and Let's see this should pop right on there like so. Yes, perfect. So now we have Cobra Commander With his battle armor helmet that is awesome. I'm gonna have him sit right here And it also includes a stand Which is helpful Hall of Fame figures did have stands, but they're a little awkward. So there's a knife and Wicked staff check this out That is That is just so wicked awesome, and I think I think that's it. So this is an amazing custom custom 12-inch Cobra Commander Just an amazing job, and I'm going to display this With my other 12 inch figures And I'll I'm gonna set him up with his his some regal Custom uniform as you said, so thank you anonymous for that really awesome artwork really awesome custom and I'm going to be careful with these things. So I don't lose them or damage them Next I'm going to do a smaller one this one Which is from it says stone gate creations And let's see And we have a letter let me pull that out first Let me give this a quick read Reading glasses would be handy, but I didn't think to grab my reading glasses before we got started here Let's see Cool. All right Custom pieces. Hey, we are all about customs this time. I love customs. That's awesome To enhance the original 3 3 quarter inch Baroness Hopefully have extra figure to use these on I think I do instructions are on the back side I think that's where I would approve of these mods. Thanks for great Content. Thank you very much a stone Fred from Stone Gate Productions Let's see what we've got here. So this oh I gotta Let me cut that open It's well packed.  Oh awesome. All right. Now. I really wish Yes, I really wish I had a zoom on this so I could show you but this is a Baroness chest piece with a That is bustier With a silver Cobra emblem that looks awesome that silver against the black is Amazing and then we've got a Custom waste piece. So I think I have an extra Baroness and I'll Swap out these parts and customize our Baroness here. Yes, I agree with you. I think Destro would approve so thank you Stone Gate creations really cool and We are keeping up the theme of customized figures. That is awesome Next I'm going to take this one off the top here This one away. This one's from Lazarus Lazarus who we who talked to sometimes in the Livestream we've Lazarus been a friend of the channel for quite some time I'm gonna give this a quick read to myself Yeah, thank you Lazarus and it says right on here. What is in the box? So if I Wouldn't want to read that to to spoil the surprise now. This Is something that you should have some familiar with if you followed the Livestream when I was doing Livestreams this is or These are Find your fates Books these are the find your fates books. I've done these live in the Livestream before This is usually fun I don't have all of the find your fates books and I think yes, these are all Books that I did not already have so Lazarus well done These are fun to do as a group activity and this will maybe be an impetus to Get back to the Livestreams. I really would like to do that. I missed the Livestreams We've got Operation Terror Trap with with Dusty on the cover We've got Operation Dragonfire with Duke on the cover And we've got Operation Deathstone with Mutt junkyard and The Baroness and the Crimson guardsmen on the cover. These are great. I love that the books themselves I love the artwork on the covers These should be a ton of fun So thank you for these and I will put these to good use as soon as I possibly can thank you very much Lazarus I am going to go to this one This is from This is from Canada. This is from Captain Foley from trek yards and I've kind of He told me that he was excited for me to open this and then I didn't get to it because geez Anyway, let's see We've got some trek yards memorabilia here and ooh, okay, so based on this I definitely should have opened this sooner. So my apologies to trek yards. I am terrible But I'm getting to it right now. Yeah Right there. Look at that What we have here, what should I pull out first? Oh, yeah, okay now we've got some Let me pull this out some Star Trek These I assume are our trek yards pins That will go perfectly with my with my pins Those are gorgeous. These are really nice These are really nice Yes, this right here Trek yards T-shirt yes Beautiful Yes, and then some trek yard stickers which he mentioned. Oh, yes On a pin that I can put on my patch I'm excuse me. That's nothing to sneeze at I Can put on my passion pen this church These are awesome. You've got some nice merchandise here. I don't have merchandise this nice This is some really good stuff here. What we have here snacks Canadian snacks Let's see. These are all yes, they're all sealed. Oh, hey cool got like more trek yard stuff I've got to take the track yard stuff out because I don't want them to get messed up I'm gonna set them over here Really nice merchandise. I have to say I need better merch That's like like all reflective and stuff. That's cool That's with it. Awesome So what we have there's more With your with your likenesses on it We have Canadian snacks Including some candy bars. So that means that right at this moment. I need to do a Tasting a tasting. Let's see We have Smarties and my recollection is that these smarties are nothing like Smarties that we have in the States. These I think are chocolate Candy with a candy coating it's similar to our M&Ms, but Let's see But with different colors Yeah, I'm a fan of smarties. Marty's are good Not smarties. We've got two kinds of arrow bars this one is I Think this is just chocolate The the original I guess let's just tear into this here real quick Break off a little bite here I approve that But then we also have Peppermint so let's see how pepperminty The peppermint is Let's see here. We go. Oh No, it's quite pepperminty Refreshing it's kind of like an Andy's mint We've got a Coffee crisp. All right Let's Peel this open I'm gonna try a coffee crisp Ready. Oh, I like that. I think that was my favorite so far It's um The flavor is kind of subtle. All right, let's move on to I add it upside down, but Lay's ketchup Lay's ketchup A flavor that I've not seen in the United States. So let's see what we got here. That is amazing They very precisely caught I captured The ketchup flavor in chip form I think I like them It's kind of um Zingy very nice Well done, Canada. I want this one all dress Looks like we've got salt and onion and bell pepper and ruffles Let's try this out You know That one's much more subtle All right, one more It says Canada's very own You know, I could honestly I could eat a bag of both of these And I will eat a bag of both of these. So, uh, thank you, mr. Captain fully and trek yards Really cool stuff. I love the t-shirt. I love all of this. Um, and I'm going to set these, uh Chips bags aside because um, oh, yeah, I missed this The card for steward foley host comma creator trek yards Very nice. Nice classy classy So thank you for that. I'm going to make sure I don't lose these That was awesome now I'm going to reach for this one because It's the closest Oh, this is from gill tucker another friend of the channel So let's see what Gil has sent He has written us a note here real quick. Oh, well, um, it says super late birthday gift and I'm super late opening it So I apologize for that, but it says here what, uh, he has included. Oh, right. Cool Well, now that he's explained what it is Let me show you, uh, let's see this should be Oh, yeah so You know, there's this new, uh, six inch gijo toy line out Uh, and you may also know that my favorite character in gijo is stalker well What gill has done Is make a custom six inch stalker figure that is amazing Really great camouflage on that um That this looks like stalker If they if they were to do a an actual, um released six inch stalker It wouldn't be any better than that. This looks exactly like Like my buddy like my buddy stalker Um, let me see if I can get It's always a little bit tricky to get. Um, oh that worked I was going to say it's sometimes tricky to get, um weapons in the six inch figure's hands but Let me get it a little bit better than that um, he's got his, um m16 With the scope Uh, that was his weapon of choice, uh in the vietnam era So there you go. That is awesome, sir. Thank you so much gill Thank you for your work in creating this and yeah Just as um, oh there's a knife. Sorry I almost missed the knife. Um, is there a Let's see. I don't see where the knife goes, uh, but I can put them in his hand. There we go. Um As I am going to display my 12 inch cobra commander custom with, um my 12 inch figures I will display this With my six inch figures. So let's let's get him to Here we'll set that there and him to sit down He and cobra commander are gonna be buddies just for a minute So thank you y'all that is really awesome So next I will go with this smaller one It is from michael miller And uh, let's see what we got Let's see no no letter with this one But uh, but a ton of accessories Um scaled up look like this looks like a a scaled up translucent stalker Um submachine gun Yeah, check that out So these have got to be customs as well So that's the theme is is customs and I if this is a Yeah, I'm just checking to see if this is about the right scale. That's about the right scale for a six inch stalker So, uh, I'm going to put that with stalker. Um So these are like, um Six inch scale, um weapons For the figures because if you've been following at all, um the uh The six inch figures have not Had, um Their original accessories What do you do in that situation? You make some which it looks like that's what he's done here Um, this is really awesome, uh to michael. Thank you um Yeah, that looks like uh a A jet pack that you could perhaps put on duke or stalker right here That's so cool. So, uh, again, I We we've got a theme here. It's a really awesome theme. It's a theme of Uh customs and um And I just love it. I I love the customs, but I also love the amount of work that you guys have put into these Um, so thank you very much for that I'm going to grab this one because it is the next one closer. This is from It looks like daniel And Daniel sends I can see what it is, but let me Quick you read this Uh, thank you. Daniel. Let's see. Let me show everyone what We got we have Hall of Fame snake eyes Hall of Fame snake eyes Um, this is this hall of fame snake eyes figure 12 inch like uh cobra commander here Uh, this is based on snake eyes version four Uh, which I reviewed recently And it looks like it's got all of his accessories and his stand here So that's awesome. Um, I had an incomplete one Um, but this appears to have everything including Is big chunky, uh, uzi. Let's see Yeah, um, the the battery doesn't work. This is a sound making gun um, but If i'm not mistaken They did not Leave you away or give you away To replace the batteries in this thing. So once the battery Ran out in in the 1990s Uh, it's just uh, you just don't get the sound making gimmick again But uh, that's awesome Got Uh, I got a a dog tag figure stand here and of course we have Uh, his dog tags, which I'm going to see if I can just put yeah His dog tags, which is a a symbol of quality Um, so uh, he's gonna be friends with uh 12 inch cobra commander here That's a wicked awesome sword. The sword is like gigantic Um, so thank you very much for that Uh, I'm going to keep these together And I'm going to move on to this box here Um, and this I believe is from our friends, uh, painted plastic from youtube And let's see what painted plastic has sent Let's see first Okay, that's all packing Um, oh, okay, okay Oh, okay. Okay. Okay. Okay. Oh look. Oh, yes. Yes. Yes. Yes. Yes From cobra convergence right there it is The shock and awe the custom that Painted plastic made for cobra convergers five. There is the actual thing that is awesome. Thank you so much Uh continuing our theme of customs and there's the driver. I'm just going to set him up a little bit there um With file cards With file cards, that's so great Uh, this is gorgeous. Um, I love the the custom when I saw it, uh for cobra convergence five And it's just more impressive in hand Painted plastic does some amazing custom vehicles and that's not something you see as often. Um, You get a lot of custom figures as you've seen here Custom vehicles are not done quite as often. So It's just awesome to see somebody tackle that task and produce something as cool as the shock and awe So thank you and there is another Box here that says on the box what it is. It says defiant wheels This is great. I'm still trying to put together the defiant Um, as some of you may know, I'll go ahead and Tape here You may or may not know but the us, uh The the gi jo defiant space complex Has a design flaw in that It's uh The the complex itself the Crawler the gantry all of that It's too heavy for the plastic wheels That it comes with and it often has wheels broken Um, but right there. Yeah, check that out We have Some defiant wheels that is awesome So this will help me This will help me, uh, get the defiant into shape So I can eventually review it. I was really hoping to review it as the first video of the year for 2021 um, but um It's really difficult to uh To complete that. Um, so that helps me a great deal. So, uh, thank you very much painted plastic For the custom and for the defiant wheels and for just all that you do you have a great channel Make sure you check out, um Painted plastics channel on youtube And that brings us to the last one The biggest one This is from It should say on here Screamin' Eman Productions. Yes Screamin' Eman Productions And I think Given what uh Screamin' Eman Productions has been working on. I think I know what we've got here Uh Let's just Pop that open. Yes. Yes Yes So, um, I showed you, um a little while back The, uh replica Uh Cobra Viper glider that Screamin' Eman Productions produced. Well, this is the companion piece If I can get the Carefully move that They have now made I can get it. I can get it. It's it's it's packed properly. It's packed very well um The companion piece The G. I. Cho falcon glider and um This I'm gonna keep this in the box. I did open the Uh Cobra Viper glider, but um this one I feel like she she's gonna stay sealed. This is just Uh The box is amazing And um It says Two HCC 788 One of one This is a replica. Um, it is designed as a replica. Um, it has significant differences from the original So you can tell it apart from the original This does not include an action figure and the original did include an action figure It included grunt version two the tan grunt. Um, it's got his picture on there, but No window pane for the action figure and each of the parts are also distinguishable From the original so you can tell this apart from an original one So for a reproduction for me, that's important that it is distinguishable From the original so nobody gets those mixed up and thinks that they're getting Getting the vintage version when in fact they're getting a reproduction Well, they've thought of that and they've done this in my view properly Um, and I think that that's awesome. So, uh, thank you Eric Eman and Screamin Eman productions for this And thank all of you. Um, uh, this is So much and it's so overwhelming and it's not just The stuff, I mean, I appreciate you taking the time to send things to me But these are a lot of things that you've created or things that are important to you and That just makes them more special So thank you Uh, I can't thank you enough. I apologize for taking so long to open these But thank you for being here with me while I open these up and check them out Um, and that is all for now. I want to Um, I want to let everyone go. I'm going to open the the letters and read those now But, um We're going to get back to normal. We will make it. We will make it back To my normal routine. Um, it's just going to take a little while But I miss you guys. Um Um, joining you once a week and talking about GI Joe was a very important part of my life And that's not something that is easy for me to Give up So, um, it's very important to me to get back to that and I promise I will as soon as I possibly can But that's all for now. Um, I will Join you again as soon as I possibly can with a vintage GI Joe toy review until then Please remember only GI Joe is GI Joe


Hello, my name is Ores Canvubilis and I'm really happy to be presenting this joint work with Nicodori Nejuivaravolta, titled Great 1.1.2 full homomorphic encryption. First off, I'm going to start with some introduction about everything that I just mentioned in the title, starting with full homomorphic encryption, or F8C scheme, which is basically an encryption scheme that allows analysts to encrypt some messages in, such that later Bob, holding an arbitrary function F, can compute the encryption of F8C. In other words, we want for Bob to be able to perform computations over encrypted data without first having to put the original messages. Now, this is very interesting in the setting where we have a worker client that wants to outsource computations to a more powerful server. That's why in the figure we have for Ken, who's supposed to be the worker client and Superman, who's the more powerful server. Of course, in a setting like this, we want to achieve security. And first of all, we want semantic security, which means that we want for Alice's message M to be hidden at all times. Or in other words, we want Bob or the server to not be able to tell apart encryption of two different messages, M0 and M1. Now, apart from security for Alice or client, also you want security for Bob, which comes in the form of server privacy. That means that we want for the client or Alice to not get any information about the server creation function used for the computation. Now, when talking about server privacy, you can refer either to the Wicker notion of semi-owner server privacy, where server privacy holds only for well-informed messages from Alice, or we can refer to the stronger notion of malicious server privacy, where it holds for any arbitrary message from Alice. Now, in this paper from Mostofsky et al, they actually showed a way to compile any classical FAT which is semi-owner server private into a malicious server private one. Now, apart from security, we also want to achieve efficiency, especially if we opt to use these schemes in real life systems. And what happens is because of security reasons, the message from the server to the client is bigger. So there's a communication overhead introduced, and we want that to not be too big, so as to nullify the efficiency of outsourcing the computations in the first place. And that's why the communication complexity is of very high interest, and we want for communication complexity to be compact, and that means to be dependent of the size of the server used for the computation. And if that's true, then the communication overhead is not too big, and we can use it in applications, such as security by using function, or an encrypted databases, such as in private information retrieval, where we retrieve an item from a database without revealing which one. And so the best communication complexity of an FAT was introduced in this paper by Ebrokesky et al, where it approaches that of the insecure protocol, where Alice would just send her message in plain. So we have an asymptotically optimal efficiency here. Now, as a metric for communication complexity, we're going to use rate, which is basically the message to site the X-ray signal. But if you want to get a bit more technical, it's the size of the encrypted data in plain over the size of the homomorphically evaluated data under encryption. Now, we want the rate to be as big as possible, because we want the homomorphically evaluated data to be as small as possible. And when we refer to rate 1 schemes, we refer to schemes that asymptotically approach rate equal to 1, such as the one adopted before from Ebrokesky et al. Now, what happens if we move to the quantum setting? Of course, we also have quantum for the homomorphic encryption schemes. And it's basically the same notion. But here we have, instead of a classical message, we have a quantum state sign. And both the client and the server can be quantum. And of course, instead of a function, we have a unitary matrix because in order to perform quantum computations, you have to do that with a unitary matrix. Now, much less is known for the quantum setting. But in our opinion, it's even more important to do the large gap between quantum capabilities of regular users and servers on the cloud in the future. And the more important, the more interesting case here is why we have a quantum output, because the classical output, maybe we can use classical techniques to to store it optimally and get the rate 1. But if we have a quantum output, again, much less is known for the quantum setting. So this is exactly the question we pose. If we can get a rate 1 secure quantum FAT, and the result is yes, that's exactly what we construct. So we're getting quantum FATC in the malicious setting with optimal communication complexity. And in order to do that, we do it with a combination of two main technical steps. First, we construct the maliciously circuit private quantum FATC. And then we construct a rate 1 quantum FATC. Now, these results, they can be independent interests, but they're also compatible with each other. So we can combine them and get our main result. Now, before getting into any actual construction or paper, I need to talk about some existing quantum free home of encryption scheme and techniques that we're going to use. And I want to start with some intuition about why we can use classical methods and the methods of classical encryption schemes and just extend them into the quantum setting. And why this is not trivial. And one of the reasons is interference. So in quantum computations, interference is very important. And what it means is that elements of the superposition representing the same bit stream, but with opposite amplitudes, they cancel out. And to make this more evident, I'm going to use an example. And I'm going to focus on the Hanover transformation. Now, this is a quantum transformation, a quantum computation. And here you can see the Hanover transformation within the ket zero. And here with ket one, with the symbol ket, we symbolize qubits. And the actual result is not too important. But what I want to focus on is that if we apply the Hanover transformation onto this superposition and replace Hanover of zero, ket zero and Hanover of ket one, we get this result. And here we have ket one, and we have minus ket one, where these are qubits with the same bit stream, but opposite amplitudes, so they cancel out. And the result is ket zero. And that thing is really important for quantum business.  So we use classical methods for this. The result would look kind of like this. By the way, what happens is that in classical encryptions, we have probabilistic encryptions, which means that its bit can have many different encryptions. So this ket encryption one and this ket one encryption one, they're not the same. And thus they cannot cancel each other, so interferes with the work. So that's why we're not just using classical techniques. Now, in order to solve the problem, we use the quantum one-time pad. Now, the quantum one-time pad is a similar notion to the classical one-time pad, but instead of using a string and extraordinary with our messes, we use these Pauli operators, which are just unitary matrices, and we have x instead. Now, x, if applied on cubic, performs a flip bit. Just like the classical one-time pad. And the separator performs a phase shift. So now, if we want to apply a quantum one-time pad, what we do is we sample a one-time key, lower case x and lower case z. So we assemble two bits. And let's say we apply the quantum one-time pad into this arbitrary superposition. What we do is apply x to the power of x instead to the power of z. So what happens here is that if x equals 0, nothing happens, the Pauli operator x is not applied. But if x, lower case x equals 1, then we apply the operator x and we perform bit flip. The same thing for z. If it's 0, nothing happens. If it's 1, we perform the phase shift. And it is proven that the result of this computation is a completely hidden quantum state, statistically hidden. And of course, you can only confirm back if you know the one-time keys, if you know x and z. Now, using this quantum one-time pad, there have been some constructions of quantum ATT. There was also one from Brookesky in the same year, but I'm going to focus on the one from Hadeb because this is the one we're also going to use. And the main idea here is that you can use a hybrid ciphertext. A ciphertext in a hybrid form that has both the quantum part and the classical part. So if we have a message sign, the client sends the quantum one-time padded state of the message along with the encryption of the one-time keys using a full comorbid encryption scheme. And then she shows her way on how to apply quantum computations on the one-time pad states. So here we apply the under a hue that are dependent on the classical comorbid computations of the keys. So we send this hybrid ciphertext that has the quantum one-time padded state along with the encryption of the keys. And then the server performs computations. Now the keys change, but he also updates the keys. I'm going to repeat this again one more time in a slide. So what we do is perform classical homework computations on the classical keys along with dependent quantum computations. So let's say we have like an interview and this is our original message. Now the quantum one-time padded state is still a quantum one-time padded state of the evaluated message. But the keys are different, but they're simultaneously updated under encryption. And thus, in the end, when we get the last message, we can to create the classical encryption, get the classical keys, one-time keys and use it to get our evaluated message. Now, just to get a bit of intuition in order to do this transformation and have a fully homomorphic encryption scheme, we want a universal set of gates. And one universal set is cliford gates along with the top of the gate. Now the cliford gates are the easy keys because the cliford gates they preserve the poly matrices by conjugation. So if we apply cliford gate, if this unit is a cliford gate, the structure looks the same after like from implementation. And just the keys are different, but it's trivial to some baby keys. Now the problem is with the top of the gate where the case is not the same. And at some point we would have to perform a quantum operation dependent on the classical keys. Of course, this is not trivial at all. And the results are interesting, but I'm not going to get into details. What I'm going to say is that Mohamed showed that if you have a classical AC scheme with certain properties, specific properties, then you can use that to do this computation here. And thus, you can use it to evaluate quantum circuits. And the classical AC with set properties is called the quantum capable AC scheme. Now, in our constructions, what we need and the properties of interest to us are that the scheme has this hybrid ciphertext consisting of the quantum part, which is our quantum anti-messages, and the classical part, which is a classical encryption of the classical, again, quantum keys of the quantum anti-message state. And we also use that the classical component of the ciphertext, so the classical AC, satisfies semi-honest rubric privacy. And by using these properties, and actually for any quantum AC with these properties, we have our results that I also mentioned earlier. So we leave the protocol from semi-honest security to my list of these rubric private security. And we also construct a rate one quantum AC. Now in this presentation, I'm just going to focus on the rate one part. And to begin with, I'm going to let's take a look at the rate of existing quantum AC protocols. For example, in the Mohamed scheme, if you remember, the rate was the message ciphertext or the evaluated message in plane over the homomorphic evaluated message. Now the actual message is just all qubits. But the homomorphic evaluated message, if you remember, would have the quantum part, which is still a qubit, because the quantum anti-message doesn't introduce any more size, plus the size of the classical keys of the homomorphic evaluated classical keys. And now this definition of rate looks a bit weird, because we combine both qubits and bits, but this is fine, because basically both qubits and bits are the most basic unit of info in their corresponding setting. And yeah, so this is a rate of a quantum AC scheme right now. But the classical utility that we use is now rate one actually blows up the ciphertext by polynomial factor. And thus the overall rate is very low, we have inverse polynomial rate. We aim to increase that. Before getting into the construction again, I want to focus on the failed approach to get some more intuition. So the quantum part, we cannot make them smaller, it's already optimal. So we have to shrink the classical information. And one idea is to use a pseudorandom generator. Now a pseudorandom generator is, well it's an generator, well if you put a small string, which is called the seed, you get a seemingly random string, bigger string. And the idea here is that instead of storing the whole one-time key, you just hold the seed that if you input it to the pseudorandom generator, you get the whole one-time key, which is the one-time key for many qubits, right? And that seems like a great idea at first, because this is how you would look, and instead of here storing the, like the one-time key would be the pseudorandom generator of the seed, and then here you would just store the seed. But the problem is that even after one homework evaluation, if you remember, the one-time key changed. So we have a new one-time key. And this new one-time key might exist outside the support of the pseudorandom generator. Or even if it wasn't the support of the generator, we're not sure how to be able to update the seed and then still store the seed. So this fails and seems like we're stuck with an encryption of classical encryption of the one-time key that looks like this. And if you think about it, we need two classical bits to input one qubit. So it seems like we're really stuck. Now, the solution is, for the solution, we have to consider these spooky interactions. And so there are some FAC schemes that pack k classical bits into ciphertext of this form. So we have the ciphertext that has a vector c0 and then one bit for its classical bits from plaintext. Now, the interesting thing here is that these last key bits are non-locally correlated with the secret key. And that means that we can use some spooky description, that sounds cool, that by using a function F, that's really my first name. Right now, we think put this first part of the ciphertext is zero, which is first most part of the ciphertext. If we explore that with the last key bits, we get the actual description. And in this paper, by using spooky interactions, they were able to construct this rate 2050 that I mentioned earlier. Now, in our construction, what we do is we use this spooky encryption scheme to get a rate one form. And how do we do that? So in the original protocol, we have we have to have a quantity capable if it's c. And when we want to store the information with key suites to the rate one if it's c. And I'm going to show you exactly how we get this rate one form. And then if we want to continue doing form of operations, we can switch back. So basically, we use both of these schemes. That is the main idea. So the first thing we do is convert from the classical from the quantum capable if it's a scheme to this spooky scheme, that looks like this, if you remember, we have a vector c zero, and then we have one bit for its one time key bit. Right. And then the main idea is that we take, we say store the first part of the cycle takes this vector c zero and then we incorporate all of these bits into the quantum one take back. So by doing this, what happens is that by incorporating them into the quantum one take back, we'd change the one time key. So if we consider one two bits that had the one time key x and z, now the one time keys out there will have x x short with cx and z extra with cz. But that's not a problem because if you remember, the spooky description equal to this function f x short with the last bits of safer text. Now if we solve for the function f, we get the decryption x short again for the last bit of the ciphertext, but the decryption is the original one time key. And then x short with the last bit of the ciphertext, we have this exactly the updated one time key that we created by incorporating these bits into the original quantum one thing by itself. So I don't know this color to technical, but the main idea here is that we get this spooky form. And we have the ciphertext that's in two parts, we just store the first part, this vector c zero, which is very small. And then the rest of the bits we incorporated into the quantum one time pad. And then by just using the function f, we can get the new updated keys just by storing this small part of the second. Now, if we take a look at the rate of this construction, of course, the message was al qubits, let's say we have an al qubit state. Now in the compressed evaluated safer text, the quantum information still al qubits, but the class confirmation is just this vector c zero. So calculate the rate, it looks a bit like this. And if we set the parameters accordingly, and we have l that's big enough, we can get rate asymptotically equal to one, just by assuming polynomial model noise ratio LWB. Great. So now this is the main construction of our protocol. And it is a generic approach because it works for any quantum FHC with these properties that I talked about. And what we do again to sum it up is we have the quantum capable FHC and we also have the rate one FHC and we key switch from one to the other to store it and then we can switch back to perform more computations. So in the full version of the paper, we also have another approach in non generic approach, which was built specifically on the Mahadev scheme, in which instead of having two FHC and key switching from one to the other, we construct a different classical FHC scheme that it's both quantum capable and rate one. So the scheme again uses this spooky properties, and we have to prove that it's both quantum capable, and we also have to prove that it is rate one. But the idea is essentially the same, but instead of key switching from one scheme to the other, we combine the best of both worlds and we get one scheme that is both. And that's basically it. I'm going to sum up the results one last time. So again, what we construct in this paper is a maliciously circuit private rate one quantum FHC. So by assuming a quantum FHC with this hybrid ciphertext form, we first leaves the protocol to maliciously circuit privacy. And then we also get optimal communication complexity construct the rate one quantum FHC. Here we have the link to the full version of the paper if you want to take it out for more details. And that's, that's pretty much it. Thank you and bye.
