Lightweight Secure Message Broadcasting Protocol for Vehicle-to-Vehicle Communication

摘要

Vehicular communications are used in various safety and business applications in today's technological world for user benefits. In this, vehicle-to-vehicle (V2V) communication enables users to exchange meaningful information with nearby vehicles directly. In general, vehicles move faster on the highway rather than the intersection road environment, and thus, a robust system is required to communicate efficiently and securely. Recently, researchers have designed various message dissemination schemes, but different concerns (i.e., security threats, more execution time, high communication overhead, and storage cost) are present in these systems, and it leads to unreliability for on-the-fly communication. Therefore, in this article, we propose an efficient and secure V2V data transmission protocol using a one-way hash function to send valuable information at the receiver side quickly. The results present that the suggested scheme performs better in execution time, storage cost, communication overhead, and energy consumption compared to the existing V2V protocols. Further, the proposed method resists various security attacks, i.e., modification, impersonation, replay, man-in-the-middle, stolen on-board-unit, password guessing, and concatenation.
