WebMay 20, 2024 · AES, like all good block ciphers, performs a “keyed permutation”. This means that it maps every possible input block to a unique output block, with a key determining which permutation to perform. A “block” just refers to a fixed number of bits or bytes, which may represent any kind of data. AES processes a block and outputs another ...
