Provably secure and efficient anonymous ID-based authentication protocol for mobile devices using bilinear pairings

With rapid development and massive deployment of handheld mobile devices, people in modern societies heavily enjoy and depend on the convenience and efficiency of instant information access and data processing through wireless Internet connection capability of their own mobile devices. In consequence, how to securely communicate with remote servers and access inquired data through insecure wireless channel, and to keep low energy consumption on handheld mobile devices, while performing these security computing operations, has become a major challenge for designers of secure authentication protocol. This study proposes a provably secure and efficient ID-based authentication protocol using bilinear pairings for mobile user environment. Formal security analyses show the proposed protocol is secure against well-known attacks under random oracle model. Comparisons on performance efficiency and security among existing pairings based protocols and ours are conducted to evaluate our protocol. The results indicate that our protocol has the less computation cost at the mobile user side and supports more security properties in comparison with others.
