| Abstract(in English) | We search differential/linear characteristics of the SC2000 block cipher. Taking account of periodicity of SC2000, we search certain types of differential/linear characteristics with six-round period. Among them we find differential characteristics with probability 2^<-58> and a linear characteristic with deviation 2-<-49.66>. By using the linear characteristic, we can attack 13-round SC2000 with 2^<99.32> known plaintext/ciphertext pairs and 2^<109.32> encryptions. |
