摘要: 随着各种交通问题的增加,车载自组织网络的各种应用不断被提出,其安全性也成为研究的焦点。基于无证 书公钥系统,提出了高效的安全V2I通信协议,其既避免了基于传统公钥系统的协议需做证书验证和维护的缺陷,又 避免了基于身份的公钥密码系统的协议中密钥分发的缺陷。与具有相同安全级别的一个基于证书的安全V2I通信协 议相比,本协议的效率提高了一倍,它更适合于车载自组织网络。

Abstract: With the increase of traffic problems,various applications of vehicular Ad hoc networks(VANEh) arc pro- posed. And their security is receiving increasing attention. This paper proposed a secure vehicl}to-infrastructure com- munication protocol based on certificateless public key cryptosystem. The proposed protocol combines the advantages of the protocol based on traditional public key cryptosystem(no key escrow) and that based on II}PKC(implicit authenti- canon). Compared with a certificate based protocol at the same security level, the efficiency of the proposed approach is
