Anonymous Authentication for Wireless Access in Internet from Pairings

Abstract

While we power on a mobile station in the GSM system, the Visitor Location Register will authenticate the validity of the mobile user in control traffic and the anonymity is infeasible. However, in GSM/GRPS-like packet-switching-based system, for the server in the Internet, the anonymity of mobile user is workable. In this paper, we present a proposed protocol to achieve anonymous wireless access of the server of Internet on the GSM/GPRS-like system. The proposed scheme is based on the Elliptic Curve Cryptography and the bilinear pairings. It has the merits of Elliptic Curve Cryptography and can be easily applied to the existing GSM/GPRS system.
