中文摘要: 为了解决车载通信网中信息的可认证性、匿名性、不可链接性和可追踪性等安全需求,根据车载通信网规模大、易变动和低时延的特点,提出了一种易扩展的安全高效的信息鉴别方案。该方案采用移动通信模式的群组管理,以基于身份的签密算法和群签名为基础,实现了车辆可以在不泄露隐私的前提下动态地加入一个群,并且可以在群中进行信息的批量验证,使信息认证时间不以车辆数的变多而增加。安全分析和实验仿真表明,该方案比现存方案可操作性强,效率高并且安全性好。

Abstract:In order to resolve the information security problem in vehicular ad hoc networks (VANET) and improve traffic efficiency, a privacy preserving and scalable scheme was proposed for VANET messages authentication, in which identity (ID)-based signcryption was used to help vehicles to securely receive a secret member key from an RSU, and then the vehicles could anonymously send messages on behalf of the group. Furthermore, batch technique was employed to accelerate the verification. Extensive simulation was conducted to confirm the efficiency of the scheme in various application scenarios. The results showed that the scheme is better than other existed programs.
