Recently, two authentication schemes with anonymity for roaming service in wireless networks were proposed by He et al . and Xu et al. In this paper we point out that neither of the two schemes is sufficiently practical owing to the high computational cost involved. Furthermore, we also find that both schemes still have some weaknesses which allow the attacker to trace a certain user's behaviors and thus infer his real identity. Thereafter, we propose a novel lightweight authentication scheme with anonymity for roaming service in global mobility networks to overcome the aforementioned defects. Moreover, we formally analyze our proposed scheme with BAN‐logic and show that it can withstand several possible attacks. Copyright © 2010 John Wiley & Sons, Ltd.
