摘要

Trust is a useful model for the interactions of Vehicular Ad Hoc Network (VANET) in Vehicular Cyber-Physical System (VCPS). Given a dynamic nature in transportation, traditional static trust models cannot effectively create the trust relationship among moving vehicles, and cannot handle quickly and dynamically the frequent vehicular interactions in a network topology. A novel trust model of VANET in VCPS is proposed to theorize the trust relationship in the dynamic traffic environment and perform a verification through an improved trust chain and some trusted computing theories. This trust model developed can improve the vehicular interaction security and the driving safety and resist malicious attacks and deceptions. Another, the vehicular trustworthiness is evaluated for the trust model development. The simulation experimental results show that the proposed trust model has a better performance for transportation applications than traditional models.
