摘　　要：车载自组网具有极高的应用前景和研究价值，随之而来的安全和隐私保护的问题成为对其部署的主要障碍。讨论了在VANET环境下单播通讯、组内共享消息时的身份验证、恶意和虚假数据识别以及隐私保护等相关安全问题，并且针对这些问题提出了一个行之有效的安全框架。该框架考虑了VANET网络环境的特殊性，在实现数据完整性、不可否认性的同时，尽可能降低通信时延。在隐私保护方面，车辆定时的更换假名，并且以组长为代理匿名接入基于位置的服务。Vehicular Ad Hoc Networks （VANET） is of high value in prospects and research, while security and privacy protection issues have become major obstacles to its deployment. This paper discusses a series of security problems in VANET, including such security issues as unicast com- munication, authentication while broadcasting in groups, recognition of malicious and false data and privacy protection. It proposes effective security architecture for the matters above, which takes particularity of the network environment into account. While ensuring data integrity and non-repudia- tion, it lowers communication delay. In order to provide privacy protection, vehicles change pseudonyms periodically and the group leader is regarded as agency for their anonymous access to location-based services.
