The overall structure is one of the most important properties of block ciphers. At present, the most common structures include Feistel structure, SP structure, MISTY structure, L-M...
Abstract. Camellia and MISTY1 are Feistel block ciphers. In this paper, we observe that, when conducting impossible differential cryptanalysis on Camellia and MISTY1, their round s...

In this paper we introduce a structure iterated by the rule A of Skipjack and show that this structure is provably resistant against differential or linear attacks. It is the main ...

ICE is a 64-bit block cipher presented at the Fast Software Encryption Workshop in January 1997. It introduced the concept of a keyed permutation to improve the resistance against ...
