Abstract

We present a modification of KASUMI type permutations and analyze the security of it using the notion of pseudorandomness. Our modified KASUMI type permutation can be computed more efficiently than the original KASUMI type permutation. Furthermore, our results have a slightly better (same) upper bound of success probability against arbitrary attackers in the sense of (super) pseudorandomness.
