摘要:

提出一种高效的群组协商通信协议,针对节点身份认证的效率问题,采用群内节点自检认证的方式,避免向认证中心发送认证证书,从而提高身份认证的速度;针对通信的机密性和单点失败现象,采用节点协商建立群组的方法,进而实现节点间的可靠通信;针对合法车辆认证次数频繁问题,采用群密钥传输机制,减少合法车辆的认证次数,进而提高节点加入群组的速度。最后,安全性分析和性能分析结果表明,所提方案不但满足车载自组网(VANET,vehicle ad hoc network)通信的基本安全需求,并且在认证时延、传输开销和平均时延方面优于现有方案。

Abstract:

An efficient communication protocol of group negotiation was proposed.The protocol adopted self-checking authentication in group to avoid the nodes sending certificates to the authentication center which improved the efficiency of identification.At the same time,the group establishment among nodes which through negotiation ensured the communication confidentiality and prevented the phenomenon of single-point failure.Besides,a group key transmission scheme was proposed to reduce the frequency of authentication for legal vehicles and improve the speed of joining in the group.At the end,theoretical analysis and simulation results demonstrate that the proposed protocol not only meets the security requirements of communication in VANET,but also shows much better performance than previous reported schemes on verification delay,transmission overhead and average delay.

Key words: efficient authentication, key negotiation, group communication, vehicle ad hoc network
