中文摘要： 新兴的车载自组织网络（VANET）对促进下一代ITS的发展，改善交通和提高行车安全有着巨大的推动作用。VANET中身份、隐私、信任之间存在的冲突破坏了车辆间的安全可靠协作，成为阻碍VANET广泛部署的重要因素。本项目拟从动态群组构建与身份管理出发，联合采用车辆节点间相互认证与快速交叉认证机制，构建车辆节点的动态身份切换与链接模型。融合车辆节点身份、位置、上下文、历史交互经验、数据等维度信息，研究面向多方面因素动态变化的综合信任建模理论与方法，揭示跨组间车辆节点信任度量的复杂性与不稳定性消除机制，进一步提出一种动态群组信任模型。分析探查在VANET数据聚集过程中起关键作用的组头节点，对组头节点调控数据聚集的过程与机制进行研究，提出基于信任度的数据聚集算法.本项目研究达到从整体上增强系统安全性与可靠性的目的，同时也为VANET中安全、隐私与信任之间的均衡与调控机理研究提供有益的探索与实践。

英文摘要： The research of emerging Vehicular Ad Hoc Networks (VANETs) has an enormous boost to promote the development of ITS next generation, improving traffic and increase road safety. The conflict among identity, privacy and trust destroy collaboration，and become an important factor for impeding VANET widely. For further in-depth study on secure, reliable collaboration mechanisms in VANETs, and discuss about the theory and methods of balance among privacy, trust and security. This project aims at foundation from dynamic group construction and identity management, joint mutual authentication between vehicle nodes and fast cross-certification mechanism between the vehicle node and the RSU. Construct a model of dynamic identity-switching and link for the vehicle nodes to eliminate the conflict between identity management and privacy protection. Research on the combined trust modeling theory and methods oriented to a number of dynamic changes factors by fusion of multi dimensions information, such as vehicle node identity, location, history, context, interactive experience, data etc. Discuss the mechanism of eliminate instability and complexity of trust metric for nodes cross groups based on the RSU, and further, a dynamic trust model for group is proposed. Analyze and probes the group head which played a key role in the p
