An efficient and secure anonymous mobility network authentication scheme

The demands of Internet users are steadily increasing. Many users access Internet services through mobile devices via wireless networks. To prevent disclosure of private data, researchers have proposed various anonymous roaming authentication schemes which apply different technologies to provide integral security properties, such as symmetric and asymmetric encryption, digital signature, timestamp, etc. Unfortunately, some of these schemes still exhibit security and efficiency issues. In order to provide tripartite authentication and enhance efficiency, we propose an efficient and secure anonymous authentication scheme for mobility networks. According to our performance and security analysis, we can prove that our proposed scheme is able to enhance efficiency and improve security in comparison to previous schemes.
