Recently, the concept of Internet of Vehicles (IoVs) conquered the automotive industry, academia, research fields, vehicle manufacturers, etc., where vehicles are ‘intelligent ones’ capable of providing a wide variety of applications, such as traveller/driver safety, infotainment, traffic efficiency, reduced congestion, less pollution, etc. Ensuring proper authentication and secure communication are the major challenges of an IoV scenario. However, only limited works are available for authentication and communication, among them the ‘lightweight property’ is missing. Hence, in this paper, we design a lightweight mutual authentication protocol in an IoV scenario using cryptographic operations. The proposed protocol also enables a device and a server to establish a secret key, which can be used for secure communication, while minimizing the computational cost associated with the process. The protocol is implemented on two types of communication models, such as two Raspberry Pi’s connected via an intermediate desktop computer acting as the Trusted Authority (TA) and two Raspberry Pi’s connected via the cloud (here, Vehicle Server). The performance analysis results based on computation and communication cost show that the proposed protocol performs better than existing systems.

一种轻量级的车联网V2V通信相互认证协议

最近，车联网 (IoV) 的概念征服了汽车行业、学术界、研究领域、汽车制造商等，其中车辆是能够提供广泛应用的“智能汽车”，例如旅客/驾驶员安全、信息娱乐、交通效率、减少拥堵、减少污染等。确保正确的身份验证和安全通信是车联网场景的主要挑战。然而，只有有限的作品可用于身份验证和通信，其中缺少“轻量级属性”。因此，在本文中，我们使用加密操作在车联网场景中设计了一个轻量级的相互认证协议。提议的协议还使设备和服务器能够建立可用于安全通信的密钥，同时最小化与过程相关的计算成本。该协议在两种类型的通信模型上实现，例如通过充当可信机构 (TA) 的中间台式计算机连接的两个 Raspberry Pi 和通过云连接的两个 Raspberry Pi（此处为车辆服务器）。基于计算和通信成本的性能分析结果表明，该协议的性能优于现有系统。
