摘要：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. In 2012, Mun et al. proposed 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, we demonstrate the weaknesses of Mun et al.’s scheme to the attacks mentioned above. We also propose an improved secure anonymous authentication scheme for roaming services.
