DEFINITION of 'Encryption' DEFINITION of 'Encryption'. Encryption is a means of securing data using a password (key). The encryption process is simple – data is secured by translating information using an algorithm and a binary key. When the data needs to be read back, the code is decrypted using either the same key or a different key depending on the type of encryption used.

Decryption Decryption is the process of transforming data that has been rendered unreadable through encryption back to its unencrypted form. In decryption, the system extracts and converts the garbled data and transforms it to texts and images that are easily understandable not only by the reader but also by the system.

Encryption For an overview of cryptographic technology in general, see Cryptography. In cryptography, encryption is the process of encoding a message or information in such a way that only authorized parties can access it. Encryption does not of itself prevent interference, but denies the intelligible content to a would-be interceptor.

What does âencryptionâ mean? Encryption has widely been used to protect data in numerous areas, such as e-commerce, online banking, cloud storage, online communication and so forth. A simple example of a cipher can be, for instance, the replacing of the letters in a message with the ones one forward in the alphabet.

encryption Private key is a symmetric encryption method that uses the secret same key to encrypt and decrypt data. Public key is an asymmetric encryption method with an encryption (encoding) key that can be used by all authorized network users and a decryption (decoding) key that is kept secret.

What is encryption? Here’s all you need to know about encryption. Encryption algorithms. At the heart of every encrypted application is the algorithm, the math that scrambles and unscrambles data. In a nutshell, an encryption algorithm is a function which takes a string of data bytes and returns a new dataset containing unintelligible content.

public-key encryption public-key encryption. Related Terms. A cryptographic system that uses two keys -- a public key known to everyone and a private or secret key known only to the recipient of the message. When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message. Jane then uses her private key to decryptit.

Deniable encryption In cryptography and steganography, deniable encryption is encryption that allows its users to convincingly deny the fact that the data is encrypted or, assuming that the data is obviously encrypted, its users can convincingly deny that they are able to decrypt it.

Cipher In cryptography, a cipher is an algorithm for performing encryption or decryption—a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code. In common parlance, cipher is synonymous with code, as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography. Codes generally substitute ...

encryption Use encryption in a sentence. The IT professionals were hired by the young celebrity to protect her personal computer files from hackers using encryption. Most electronic financial transactions are subject to heavy encryption to prevent any sensitive information from being stolen and used for illegal purposes. 20 people found this helpful. To break into the database, Daryl needed to figure out the encryption to the mainframe computer database, so he could open the door.

symmetric-key cryptography An encryption system in which the sender and receiver of a message share a single, common key that is used to encrypt and decrypt the message. Contrast this with public-key cryptology, which utilizes two keys-a public key to encrypt messages and a private key to decrypt them.

- Encryption is the process of converting a plaintext message into ciphertext which can be decoded back into the original message. An encryption algorithm along with a key is used in the encryption and decryption of data. There are several types of data encryptions which form the basis of network security. Encryption schemes are based on block or stream ciphers.

AES (acronym of Advanced Encryption Standard) is a symmetric encryption algorithm. The algorithm was developed by two Belgian cryptographer Joan Daemen and Vincent Rijmen. AES was designed to be efficient in both hardware and software, and supports a block length of 128 bits and key lengths of 128, 192, and 256 bits.

Symmetric Encryption Symmetric encrpytion is a two-way algorithm because the mathematical algorithm is reversed when decrypting the message along with using the same secret key. Symmetric encryption is also known as private-key encryption and secure-key encryption.

encryption The translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it. Unencrypted data is called plain text; encrypted data is referred to as cipher text. There are two main types of encryption: asymmetric encryption (also called public-key encryption) and symmetric encryption.
