摘要
Techniques and apparatus for protecting sequence numbers used in authentication procedures are described. One technique includes receiving at a UE (120a), from a network (130), an authentication request comprising at least a random challenge. After receipt of the authentication request, a synchronization parameter is generated based at least in part on a key shared by the network (130) and the UE (120a), the random challenge, and a first message authentication code, MAC. The synchronization parameter and the first MAC are transmitted to the network in response to the authentication request.
