SPSC: A secure and privacy‐preserving autonomous platoon setup and communication scheme

Abstract

Summary The new driving model of autonomous platoon has outlined the blueprint for developing the intelligent transportation of system since it can improve safe driving, alleviate traffic congestion and bring more comfortable experience. Vehicles in the platoon can communicate and share driving data with each other through vehicular network for cooperatively driving. Therefore, it is crucial to avoid some misbehavior vehicles which can eavesdrop or even tamper important data. In this paper, we propose a secure and privacy‐preserving autonomous platoon setup and communication scheme, called SPSC, to help vehicles establish secure communication and avoid private information leakage. Specially, considering the dynamic and temporary characteristics of the autonomous platoon, the autonomous platoon communication can be divided into two scenarios, that is, intra‐platoon communication and inter‐platoon communication. In the intra‐platoon communication, the SPSC can securely set up platoon and dynamically manage the platoon members with privacy preservation by using private set intersection and group key agreement techniques, respectively. In the inter‐platoon communication, the SPSC can also achieve secure and anonymous communication by adopting certificateless ring signcyption technique. In addition, vehicle‐out‐platoon can trace the disputed or misbehavior platoon member with the assistance of Road Transportation Authority. The security analysis shows that SPSC can provide authentication, privacy protection, confidentiality and traceability. Finally, the performance of SPSC is comprehensively evaluated by simulation to demonstrate its efficiency in terms of the computation cost.

A Lightweight Secure Management Scheme for Energy Harvesting Dynamic Wireless Charging System

“…As one of the core technologies to promote the construction and development of ITS, Internet of Vehicle (IoV) has been widely attracted and researched by the industry and academic [3]. IoV, as a special domain in Internet of Things (IoT), realizes the collection, sharing and analysis of road information between vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P) and vehicle-to-network (V2N) via wireless communication such as dedicated short range communication (DSRC) or cellular communication (LTE or 5G) [4] [5] [6]. The de-velopment of IoV has not only enhanced driving safety and traffic efficiency, but also improved the convenience and entertainment of driving experience.…”
