Abstract

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.
VANETs组消息安全转发与信任评估
车辆之间高效、安全的信息交换可以降低道路事故发生的概率,从而改善车辆在车辆自组织网络(VANETs)中的驾驶体验。针对车辆高速行驶和行驶方向动态变化对VANETs拓扑结构造成的巨大压力,提出了一种具有信任度和机动性评价的群管理算法。该算法利用历史交互数据挖掘车辆间的融合信任。然后结合融合移动性,实现了中心成员的选择和群体成员的信息维护。在此基础上,设计了基于双线性对的加密协议,解决了组结构快速变化时密钥管理和更新的问题,保证了组内和组间消息的安全转发。数值分析表明,本文算法保证了群的稳定性,提高了平均消息传递率和交互延迟等性能。
