SAT: Building New Trust Architecture for Vehicular Networks

The new trust concept and architecture for VNET is introduced in this paper. The "Situation-Aware Trust (SAT)" uses descriptive attributes to efficiently perform security policy control, builds in mechanisms for predicting future trust situations, and transforms trust from Internet social communities to VNET trust to enhance and promote VNET applications. The secure situation-aware trust architecture establishes solutions to achieve SAT. By introducing the above concepts, the authors point a new research direction. More research efforts are required. Here are two major research issues for future study: Attribute Based Encryption (ABE) is the basic to integrate the policy control and security services for SAT.
