The AC block cipher
Sihan Qing · Journal of China Institute of Communications · 2002
AC(a cipher) is a 128-bit block cipher that accepts a 128-bit key. The cipher is a substitution-permutation network whose decryption only differs from the encryption in the key schedule. The cipher design combines the wide trail strategy and bit-slice technology that ensure the resistance AC against differential and linear cryptanalysis. The goal of this paper is the publication of the AC block cipher for public scrutiny.
