Analysis and Implementation of Trusted Node and Trusted Routing in Vehicular Ad-Hoc Network

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.
