Vehicle Ad-hoc Networks (VANETs) have experienced significant development in recent years, playing a crucial role in enhancing the driving experience by enabling safer and more efficient inter-vehicle interactions through information exchange. Vehicle-to-Vehicle (V2V) communication is particularly vital as it not only helps to prevent collisions and improve traffic efficiency but also provides essential situational awareness to drivers or autonomous driving systems. Communication is typically supported by roadside units (RSUs); however, in practical applications, vehicles may exceed the communication range of RSUs, thus exposing them to various malicious attacks. Additionally, considering the limited computational resources of onboard units (OBUs) in vehicles, there is a high demand for designing lightweight security protocols that support V2V communication. To address this issue, this paper proposes an efficient anonymous V2V identity-authentication protocol tailored for scenarios that lack RSU support. The proposed protocol was formally assessed using the Scyther tool, demonstrating its capability to withstand major typical malicious attacks. Performance evaluations indicate that the proposed protocol is efficient in terms of communication and computational overhead, making it a viable solution for V2V communication.
车载自组织网络（VANETs）近年来取得了显著发展，通过信息交换实现更安全、高效的车与车交互，在提升驾驶体验方面发挥着关键作用。车对车（V2V）通信尤为重要，因为它不仅有助于防止碰撞、提高交通效率，还为驾驶员或自动驾驶系统提供重要的态势感知。通信通常由路边单元（RSU）支持；然而，在实际应用中，车辆可能超出RSU的通信范围，从而使其容易受到各种恶意攻击。此外，考虑到车辆上的车载单元（OBU）计算资源有限，对设计支持V2V通信的轻量级安全协议有很高的需求。为解决此问题，本文针对缺乏RSU支持的场景提出了一种高效的匿名V2V身份认证协议。使用Scyther工具对所提出的协议进行了形式化评估，证明了其抵御主要典型恶意攻击的能力。性能评估表明，所提出的协议在通信和计算开销方面是高效的，使其成为V2V通信的可行解决方案。
