| Abstract(in English) | We present a modjfication of the KASUMI type permutations and analyze the security of it using the notion of pseudorandomness. Our modification is similar to the KASUMI type permutations except the use of just two round MISTY-type permutation as the round function. Note that the values of each round functions of two round MISTY-type permutation can be computed simultaneously. So our modified permuatation can be computed more efficiently than the original KASUMI type permuation. Furthermore our results have a sligtly more good (or same) upper bound of success probablity of arbitrary attacker in the sense of (super) pseudorandomness. |
