-
广义Feistel结构使用多SP形式轮函数,会对安全性带来一定的影响.首次讨论了多SP轮函数在不完全扩散情况下,安全性发生的一些变化.并对Lesamnta-256的中间置换采用的结构和轮函数进行差分分析.这是长达三轮的超级匹配技术第一次用于广义Feistel结构的算法.
- Abstract:
-
If a generalized Feistel network cipher adopts the multi-SP round function,the security is alwaysdifferent to the single-SP case. We studied this change where the multi-SP round function has a non-perfctdiffusion. We analyzed the structure and the round function of the inner permutation of Lesamnta-256 for theirdifferential properties. This is the first application of the super-match technique to a generalized Feistel algo-rithm.
