A secure and effective anonymous authentication scheme for roaming service in global mobility networks
This work improves security for roaming services in global mobility networks, though it appears incremental as it builds directly on prior schemes.
The authors identified security vulnerabilities in Mun et al.'s authentication scheme for global mobility networks and proposed a new scheme that addresses these weaknesses, showing it is secure against various attacks and suitable for low-power mobile devices.
Recently, Mun et al. analyzed Wu et al.'s authentication scheme and proposed a enhanced anonymous authentication scheme for roaming service in global mobility networks. However, through careful analysis, we find that Mun et al.'s scheme is vulnerable to impersonation attacks, off-line password guessing attacks and insider attacks, and cannot provide user friendliness, user's anonymity, proper mutual authentication and local verification. To remedy these weaknesses, in this paper we propose a novel anonymous authentication scheme for roaming service in global mobility networks. Security and performance analyses show the proposed scheme is more suitable for the low-power and resource-limited mobile devices, and is secure against various attacks and has many excellent features.
