  Abstract

Within the security architecture of the 3GPP system there is a standardised integrity algorithm . The integrity algorithm computes a MAC to authenticate the data integrity and data origin of signalling data over a radio access link of W-CDMA IMT-2000. is a variant of the standard CBC MAC based on the block cipher KASUMI. In this paper we provide the provable security of . We prove that is secure by giving concrete bound on an adversary's inability to forge in terms of her inability to distinguish the underlying block cipher from a pseudorandom permutation.
