VANETs group message secure forwarding with trust evaluation
Efficient and safe information exchange between vehicles can reduce the probability of road accidents, thereby improving the driving experience of vehicles in Vehicular Ad Hoc Networks (VANETs). This paper proposes a group management algorithm with trust and mobility evaluation to address the enormous pressure on VANETs topology caused by high-speed vehicle movement and dynamic changes in the direction of travel. This algorithm utilizes historical interactive data to mine the fusion trust between vehicles. Then, combined with fusion mobility, the selection of center members and information maintenance of group members is achieved. Furthermore, based on bilinear pairing, an encryption protocol is designed to solve the problem of key management and update when the group structure changes rapidly, ensuring the safe forwarding of messages within and between groups. Numerical analysis shows that the algorithm in the paper ensures group stability and improves performance such as average message delivery rate and interaction delay.
