On the pseudorandonmess of KASUMI type permutations
KASUMI is a block cipher which has been adopted as a standard of 3GPR In this paper, we study the pseudorandomness of idealized KASUMI type permutations for adaptive adversaries. We show that the four-round version is pseudorandom and the six-round version is super-pseudorandom.
