WebFor example, the schemes DES and AES have block sizes of 64 and 128, respectively. Stream Ciphers In this scheme, the plaintext is processed one bit at a time i. one bit of plaintext is taken, and a series of operations is performed on it to generate one bit of ciphertext. Technically, stream ciphers are block ciphers with a block size of one bit. WebNov 2, 2024 · The Hill Cipher algorithm uses an m x m sized matrix as the key to encryption and decryption.
