Universal access authentication for wireless network
He Liu, Mangui Liang, Wenjuan An · 2011
This paper proposes a universal access authentication protocol in a safe and efficient way for wireless network. Firstly, an improved hierarchical identity based signature is designed to overcome key escrow. Secondly, based on the modified signature scheme, a new authenticating protocol, namely Priauth-HIBS, is proposed. It has its own advantages, such as identity based, hierarchy, local verification and single registration. In particular, Priauth-HIBS only involves two parties to accomplish mutual authentication and key establishment, which reduces the interactional complexity and makes authentication universal in wireless network. Besides, security level is enhanced against kinds of attacks. The theoretical and simulating results shows that Priauth-HIBS provides more secure and efficient service for roaming user. A further discussion reveals our near future work at last.
