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.
