What is AES Encryption: Structure and Steps about?
This document summarizes the Advanced Encryption Standard (AES). AES is a block cipher that encrypts data in blocks of 128 bits using keys of 128, 192, or 256 bits. It operates on a 4x4 array of bytes called the state array. Each round of encryption applies four steps: byte substitution, shifting rows, mixing columns, and adding the round key. The number of rounds depends on the key size, with 10 rounds for 128-bit keys. Decryption uses similar but inverted steps in a different order than encryption.
