Improved Secure Anonymous Authentication Scheme for Roaming Service in Global Mobility Networks

The user authentication scheme in a global mobility network is an important security issue that allows users of mobile devices to access a secure roaming service through wireless networks. Over recent years, many anonymous authentication schemes have been proposed for roaming services in global mobility networks. A new enhancement for scheme that uses the Elliptic Curve Diffie - Hellman protocol to overcome security weaknesses and improve performance. However, this has some vulnerabilities, such as in the case of replay attacks and man-in-the-middle attacks. In this paper, the authors demonstrate the weaknesses of scheme to the attacks mentioned above. They also propose an improved secure anonymous authentication scheme for roaming services.
