将可信赖平台模块(TPM)芯片引入车载自组织网VANET,提出了一种有效保护地理位置信息路由协议GPSR(贪婪周边无状态路由协议)的可信安全机制,从而能够防止恶意篡改路由协议和邻居位置信息表的行为。在NS2.30下对网络真实场景进行了模拟,证实此可信安全路由协议模型是正确的、有效的和合理的。
Introducing the TPM chip into VANET,a trusted security mechanism was proposed.The new mechanism can provide a holistic protection for geographic information routing protocol GPSR,so as to effectively prevent malicious behavior such as tampering with routing protocols and neighbor location information table.As well as simulating real-life scenarios in NS2.30,comparing results confirm that the model is a correct,effective and reasonable trusted security framework for routing protocol.
