P2 COMM: A Secure and Low-Cost Message Dissemination Scheme for Connected Vehicles

Abstract

Internet of Vehicles (IoV) allows the vehicles to disseminate and exchange various messages among nearby vehicles in the network. These messages include road safety, road accidents, location sharing, driver assistance, navigation, collision warning, and toll payment. Moreover, the exchange of these messages is carried out using an insecure channel, which leads to several issues during transmission of these messages, such as reliable data dissemination, dynamic topology, mobility of the vehicles, vehicle user’s privacy, and low-cost authentication mechanism. The existing vehicle-to-anything (V2X) data dissemination techniques have issues like security attacks, high computational-communication cost, and low throughput. Motivated by these, we propose a secure and Low-Cost (V2X) data dissemination scheme known as P <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> COMM for connected vehicles using SHA256 concatenation and XoR operation. We evaluate the proposed scheme in terms of security and vehicle users’ privacy against several security attacks. Then, we carried out an in-depth formal security analysis of the proposed scheme using the AVISPA tool and informal security analysis along with security proofs. The performance of the proposed scheme is better in comparison to existing state-of-the-art schemes in terms of security, communication overhead, computation cost, and energy cost.
