| + | abstract = {We present a new type of distinguisher, called zero-sum distinguisher, and apply it to reduced versions of the Keccak-f permutation. We obtain practical and deterministic distinguishers on up to 9 rounds, and shortcut distinguishers on up to 16 rounds, out of 18 in total. These observations do not seem to affect the security of Keccak. We also briefly describe application of zero-sum distinguishers to the core permutations of Luffa and Hamsi.}, | ||
