difference between IP security issue in authentication, data encryption, and message integration?
<p>I am confused about these terms and what method or algorithm they used to achieved that. From what I learned, there are two ways for data encryption: symmetric key and public key; And message integration are done by using hash algorithm; And authentication method including public key, pre shred key etc. However, whats the relationship between these three or can someone use an example to explain them. I am really confused about these three terms. Thanks!</p>
