A novel lightweight authentication scheme with anonymity for roaming service in global mobility networks

Abstract

SUMMARYRecently, 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.

Revisiting three anonymous two-factor authentication schemes for roaming service in global mobility networks

“…In 2010, Wu et al [13] proposed a novel lightweight authentication scheme used one-way hash functions and symmetric cryptographic operations in GLOMONET for roaming service to provide user anonymity. In 2011, Zhou and Xu [14] also proposed a provable secure two-factor authentication protocol with anonymity for roaming service based on Diffie-Hellman assumption.…”

Authentication in Ubiquitous Networking

“…More authentication protocols have been proposed to overcome the anonymity issue for the roaming service in GLOMONET (Daojing He, Ma, Zhang, Chen, & Bu, 2011;Peng, Zhenfu, Kim-kwang, & Shengbao, 2009;Pu;S. Wu, Zhu, & Pu, 2011;Zhou & Xu, 2011).…”

A novel user authentication scheme with anonymity for wireless communications

“…In order to verify the identity of a legal MU and ensure anonymity of the MU to protect his or her privacy simultaneously, researchers have proposed many authentication schemes for seamless roaming over wireless communications [13][14][15][16][17][18][19][20][21][22][23]. In 2004, Zhu and Ma [23] proposed an efficient authentication scheme with anonymity for wireless communications.…”
