3:57 AM Advanced Encryption Standard (AES) algorithm : an algorithm for encryption and decryption for secure data transfer |
|
The Advanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S
AES is based on a design principle known as a substitution-permutation network, and is fast in both software and hardware.Unlike its predecessor DES, AES does not use a Feistel N/W. AES operates on a 4×4 column major-order matrix of bytes, termed the state, although some versions of Rijndael have a larger block size and have additional columns in the state. Most AES calculations are done in a special finite field.
