车载移动机会网络安全与信任机制研究

本项目是一个结合移动机会网络领域和信息安全领域的前沿技术课题。车载机会网络作为移动自组织网络的演进和极端版本，由于其利用节点相遇机会通信使得移动节点更加不可控制，对数据的机密性和完整性、路由安全性与隐私性等带来更大的挑战，有关车载机会网络安全与信任问题研究正日益受到关注。项目将通过结合车载移动节点行为，分析车载机会网络的基本特性和安全基础架构；研究车载机会网络安全路由与隐私保护，并研究如何实现隐私保护与安全路由的最佳整合；使用博弈论对车载机会网络在非合作博弈和合作博弈两种模型下分别进行深入研究，设计对应的合作激励机制；研究基于数据的信任模型和模拟方法，并且根据安全评价体系中的主要指标对整个系统进行量化评估，从而最终为车载机会网络的建设和应用奠定理论和技术基础。

This project is a frontier research concerning with both mobile opportunistic network and information security fields. As an evolutionary and extreme version of mobile ad hoc network, vehicular mobile opportunistic network utilizes the movement of nodes to seek the possible communication chance to transmit the messages hop by hop, which makes nodes more uncontrollable and brings new challenge for confidentiality,data integrity and routing security and privacy. Since security and trust related research on vehicular mobile opportunistic network receives more and more attentions nowadays, by combining the behavior of vehicular mobile nodes this project will first analyze the fundamental characteristics and security architecture, and study secure routing and privacy protection for vehicular mobile opportunistic network and optimaization of the above two features; then design the corresponding cooperation incentive mechanisms in cooperative and non-cooperative model respectively using game theory; and then by establishing data based trust model it will give a quantitative evaluation for network system after simulation; Finally it can provide theoretical and technical support for the application and deployment of vehicular mobile opportunistic network.
