Situation-Aware Trust Architecture for Vehicular Networks

The authors present a new trust architecture - Situation-Aware Trust - to address several important trust issues in vehicular networks. SAT includes three main components: An attribute-based policy control model for highly dynamic communication environments, a proactive trust model to build trust among vehicles, and prevent the breakage of existing trust, and an email-based social network trust system to enhance trust and to allow the set up of a decentralized trust framework. To deploy SAT, they utilize identity-based cryptography to integrate entity trust, data trust, security policy enforcement, and social network trust, allocating a unique identity, and a set of attributes for each entity. They conclude by presenting research challenges and potential research directions that extend this work.
