Abstract

In fog-based VANETs, fog nodes are close to the network edge that analyze data uploaded by vehicles, and then provide value-added services. It is suitable to adopt data sharing schemes to provide value-added services. However, applying existing data sharing schemes directly for service provision in fog-based VANETs has limitations in terms of security and efficiency. Therefore, we propose a dynamic secure service provision scheme in fog-based VANETs called DSSPS. Firstly, we construct an efficient subscription permission authentication mechanism that allows vehicles to request service from different fog nodes after a single subscription at TA. Secondly, a subgroup selecting algorithm is proposed, which effectively reduces the decryption overhead of vehicles. Formal security proof demonstrates DSSPS is secure. At the same time, DSSPS achieves better performance in terms of computation and communication costs.

DSSPS：基于雾的 VANET 中的动态安全服务提供方案

在基于雾的 VANET 中，雾节点靠近网络边缘，分析车辆上传的数据，然后提供增值服务。采用数据共享方案提供增值服务是合适的。然而，在基于雾的 VANET 中直接应用现有的数据共享方案来提供服务，在安全性和效率方面都有局限性。因此，我们提出了一种基于雾的 VANET 中的动态安全服务提供方案，称为 DSSPS。首先，我们构建了一种高效的订阅许可认证机制，允许车辆在 TA 处进行一次订阅后向不同的雾节点请求服务。其次，我们提出了一种分组选择算法，有效降低了车辆的解密开销。正式的安全性证明表明 DSSPS 是安全的。同时，DSSPS 在计算成本和通信成本方面取得了更好的性能。

期刊介绍： Vehicular communications is a growing area of communications between vehicles and including roadside communication infrastructure. Advances in wireless communications are making possible sharing of information through real time communications between vehicles and infrastructure. This has led to applications to increase safety of vehicles and communication between passengers and the Internet. Standardization efforts on vehicular communication are also underway to make vehicular transportation safer, greener and easier. The aim of the journal is to publish high quality peer–reviewed papers in the area of vehicular communications. The scope encompasses all types of communications involving vehicles, including vehicle–to–vehicle and vehicle–to–infrastructure. The scope includes (but not limited to) the following topics related to vehicular communications: Vehicle to vehicle and vehicle to infrastructure communications Channel modelling, modulating and coding Congestion Control and scalability issues Protocol design, testing and verification Routing in vehicular networks Security issues and countermeasures Deployment and field testing Reducing energy consumption and enhancing safety of vehicles Wireless in–car networks Data collection and dissemination methods Mobility and handover issues Safety and driver assistance applications UAV Underwater communications Autonomous cooperative driving Social networks Internet of vehicles Standardization of protocols.
