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.

车对车通信的轻量级安全消息广播协议

车载通信在当今的技术世界中被用于各种安全和商业应用中，以实现用户利益。这样，车对车（V2V）通信使用户可以直接与附近的车辆交换有意义的信息。通常，车辆在高速公路上而不是在交叉路口环境中行驶得更快，因此，需要一个强大的系统来有效且安全地进行通信。近来，研究人员设计了各种消息分发方案，但是这些系统中存在着不同的担忧（即安全威胁，更多的执行时间，较高的通信开销和存储成本），并且这导致了实时通信的不可靠性。因此，在本文中，我们提出了一种有效且安全的V2V数据传输协议，该协议使用单向哈希函数在接收方快速发送有价值的信息。结果表明，与现有的V2V协议相比，该方案在执行时间，存储成本，通信开销和能耗方面表现更好。此外，所提出的方法抵抗各种安全攻击，即，修改，模拟，重放，中间人，机载单元被盗，密码猜测和级联。
