On the Pseudorandomness of KASUMI Type Permutations
KASUMI is a block cipher which has been adopted as a standard of 3GPP. 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.
