On the Security of an Efficient Mobile Authentication Scheme for Wireless Networks
Jian-zhu Lu and Jipeng Zhou
Abstract: 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.
Category / Keywords: applications / mobile authentication; digital signature; replication attack; elliptic-curve cryptosystem.
