On the Security of an Efficient Mobile Authentication Scheme for Wireless Networks
Tang and Wu proposed an efficient mobile authentication scheme for wireless networks, and claimed the scheme can effectively defend all known attacks to mobile networks including the denial-of-service attack. This article shows an existential replication attack on the scheme and, as a result, an attacker can obtain the communication key between a mobile user and the accessed VLR. Fortunately, we improve its security in this paper.
