Abstract
As a mechanism to secure access to a global mobility network (GLOMONET), authentication for consumer roaming service is an essential technology. Moreover, as mobile consumers are getting concerned about how much information network providers gather about them, privacy preservation is a serious concern these days. In this paper, a new authentication scheme is presented that provides a robust anonymous two-factor authentication for consumer roaming service in GLOMONETs. Detailed operational phases of the proposed scheme are provided. Security analysis is provided to confirm that the proposed scheme provides anonymity, authentication, and perfect forward secrecy. In addition, the proposed scheme is analyzed whether it withstands various attacks.
