摘要:

针对跨域间车辆自组织网络中车辆与车辆之间认证与密钥协商需要服务器参与才能完成的问题,提出了一个基于口令的无服务器参与的跨域车辆与车辆之间认证与密钥协商协议。协议采用分发认证凭证的方式实现跨越认证,通过将智能卡与口令相结合的方式增强口令的安全性。在ECCDH(Elliptic Curve Computational Diffie-Hellman)困难问题下证明了协议的安全性。与已有的需要服务器参与的跨域认证与密钥协商协议相比,所提协议没有服务器参与,从而避免了因服务器无法处理大量认证请求所带来的时延。

Abstract:

Aiming at the problem that vehicle-to-vehicle (V-2-V) authentication and key agreement of cross-domain in VANETs (vehicular ad hoc networks) can be accomplished by the participation of servers,a cross-domain V-2-V password-based authentication and key agreement protocol without server participation is proposed.The protocol uses the method of distributing authentication credentials to achieve cross-authentication,and enhances the security of passwords by combining smart cards with passwords.The security of the protocol is proved under the hard problem of ECCDH (Elliptic Curve Computational Diffie-Hellman).Compared with the existing cross-domain authentication and key agreement protocol that requires server participation,the proposed protocol does not involve server participation,thus avoiding the communication delay caused by the server’s inability to process a large number of authentication requests.

Key words: VANETs, authentication and key agreement, cross-domain, without server participation, password
