Hierarchical Adaptive Trust Establishment Solution for Vehicular Networks

Cooperative intelligent transportation systems (C- ITS), mainly represented by Vehicular Ad Hoc Networks (VANETs), were developed to enhance safety on roads before being generalized to support other comfort and efficiency applications. Most VANET applications, including safety ones, are based on multi-hop communications. Hence, a certain trustworthiness should exist among vehicles to ensure a reliable and trusted communication excluding dishonest peers from all network operations. In this paper we propose an hierarchical trust establishment solution able to cope with VANET applications and their requirements. Our solution is based on a three-level architecture, which enables it to adapt to the communication scenario and the required security level.


System Architecture


Project Overview : we propose a new hybrid trust establishment solution excluding both dishonest nodes and their generated messages. Our solution can be adopted to all kinds of ex- changed traffics thanks to the use of the standardized traffic classification.
