Camellia-128的截断差分攻击改进
Improved truncated differential analysis on Camellia-128
摘要
Abstract
Based on 9-round truncated differential distinguisher presented by Makoto Sugita on ASIACRYPT2001,this paper proposed a new 10-round truncated differential distinguisher of Camellia block cipher.Moreover,by using this distinguisher and the early abort technique in process of key recovery,it attacked 12-round Camellia-128 with data complexity of 297 and time complexity of 2124.The result is the best truncated differential analysis result on reduced-round Camellia so far.关键词
