Abstract

In this paper, a method is presented to extend the length of integral distinguisher of Feistel-SP structure, based on which a new 8-round distinguisher for the block cipher Camellia is proposed. Moreover, integral attacks on round-reduced Camellia without FL/FL-1 are improved. We attack 11-round Camellia-128 with the data complexity of 2120 and the time complexity of 2125.5, and attack 12-round Camellia-256 with the data complexity of 2120 and the time complexity of 2214.3. These attacks are the best integral attacks on round-reduced Camellia so far.
