摘要
车载自组网(VANET,vehicular ad hoc networks)具有无中心、移动性和多跳传输等特点,使得传统的密钥管理方式不再适用。可信计算技术的快速发展和成功应用为解决VANET的有效认证和信任评估问题提供了一条潜在途径。针对具有自组织特性的VANET网络,基于可信计算技术提出了一种新的认证和信任评估框架,引入了可信属性和可信等级的概念,给出了密钥管理结构和移动节点认证过程,着重指出了该框架潜在的实际应用。另外,阐述了在该框架下的信任评估方法。
Vehicular ad hoc networks(VANET) have many new characteristics unlike tranditional network, such as centriclessness, mobility and multi-hop transmission, which invalidate conventional key managements.The fast development and successful application of trusted computing technology provide a potential solution to achieve effective authentica-tion and trust evaluation.According to the VANET with self-organization, a new authentication and trust evaluation framework was proposed based on trusted computing technology, the concepts of'trusted attribute'and'trusted grade'were introduced, and the key management architecture as well as authentication process of mobile node were explained in detail.Moreover, the potential real application of the presented framework was discussed, and the trust evaluation method and its argumentation in the presented framework were given.
