Lightweight anonymous authentication scheme with unlinkability in global mobility networks

چکیده
Anonymous user authentication schemes are essential to guarantee personal privacy in global mobility networks. Recently, Chung, Lee and Won proposed an improved authentication scheme with anonymity which remedies security weaknesses showed by Youn, Park and Lim. However, their improved scheme does not provide unlinkability. In this paper, we propose an anonymous authentication scheme which ensures user unlinkability. It is impossible for attackers to know particular sessions, that have already occurred several times, are originated from one same user. Moreover, we decrease the rounds of transmission among involved entities while consuming same computational power compared with previous schemes. Therefore, the proposed scheme is lightweight and suitable for the mobility networks. Keywordsauthentication; privacy; anonymity; unlinkability; mobility network; roaming service

متن کاملProvably Secure Anonymous Authentication Scheme for Roaming Service in Global Mobility Networks
This paper presents an anonymous authentication scheme for roaming service in global mobility networks, in which the foreign agent cannot obtain the identity information of the mobile user who is sending the roaming request. In addition, the home agent does not have to maintain any verification table for authenticating the mobile user. We give formal analyses to show that our proposed scheme sa...
