Abstract: A new non-proprietary secret-key block-enciphering algorithm, SAFER K64 (for Secure And Fast Encryption Routine with a Key of length 64 bits) is described. The blocklength is 64 bits (8 bytes) and only byte operationsareati in the processes of encryption and decryption. New cryptographic features in SAFER K-64 include the use of an unorthodox linear transform, called thePseudo-Hadamard 00 to achieve the desired "diffusion " of small changes in the plaintext or thekey761 the resulting ciphertext and the use of additive key biases to eliminatetheate 35144 of "weak keys". The design principles of K-64 are explained and a program isgiven,-36800 with examples, to define the encryption algorithm precisely., |
