This paper proposes a new access authentication protocol for electric vehicle in a secure and efficient way. The proposed protocol employs identity based aggregate signatures to achieve access authentication. It has the characteristics of local signals, identity based, etc. For security, the new protocol can support mutual authentication, message integrity and replay attack resistance. For efficiency,...
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...
With the promotion of people's demand on information security, access authentication gets more and more attention nowadays. However, most of the traditional access authentication schemes, such as 802.1X, Web authentication, etc., have a great deal of limitations and disadvantages in security and mobility. They can't meet increasing challenges especially from wireless authentication. In this paper,...
