All algorithms support authenticated encryption with plaintext P and additional authenticated data A (that remains unencrypted). The encryption input also includes a public nonce N, the output - authentication tag T, size of the ciphertext C is the same as that of P. The decryption uses N, A, C, and T as inputs and produces either P or signals ...
The sponge construction for hash functions. P i are blocks of the input string, Z i are hashed output blocks.. In cryptography, a sponge function or sponge construction is any of a class of algorithms with finite internal state that take an input bit stream of any length and produce an output bit stream of any desired length.
Authenticated Encryption (AE) is an encryption scheme which simultaneously assures the data confidentiality (also known as privacy: the encrypted message is impossible to understand without the knowledge of a secret key [1]) and authenticity (in other words, it is unforgeable: [2] the encrypted message includes an authentication tag that the sender can calculate only while possessing the ...
The Competition for Authenticated Encryption: Security, Applicability, and Robustness (CAESAR) is a competition organized by a group of international cryptologic researchers to encourage the design of authenticated encryption schemes. [1]
SocialDocs file encryption uses AES256 to provide a free-online file encryption tool XFire uses AES-128, AES-192 and AES 256 to encrypt usernames and passwords Certain games and engines, such as the Rockstar Advanced Game Engine used in Grand Theft Auto IV , use AES to encrypt game assets in order to deter hacking in multiplayer.

The Advanced Encryption Standard (AES) has both excellent confusion and diffusion. Its confusion look-up tables are very non-linear and good at destroying patterns. [ 14 ] Its diffusion stage spreads every part of the input to every part of the output: changing one bit of input changes half the output bits on average.
