Abstract In the past decades, Vehicular Ad hoc Networks (VANETs) have been increasingly developed. Providing secure and efficient communication is essential in VANETs. One of most important challenges in the secure and efficient communications is proposing an appropriate authentication scheme. In this paper, we suggest an efficient and novel authentication scheme for VANETs. In the proposed scheme, vehicles authenticate each other without any limitation such as need for group of signers, online Road Side Units (RSUs), a set of pseudo identities and tamper-proof devices. Moreover, our simulation shows that the proposed scheme is well designed and efficient.

一种新的、高效的车载自组织网络认证方案

摘要 在过去的几十年里，车载自组织网络（VANETs）得到了越来越多的发展。提供安全高效的通信对于 VANET 至关重要。安全高效通信中最重要的挑战之一是提出适当的身份验证方案。在本文中，我们为 VANET 提出了一种有效且新颖的身份验证方案。在所提出的方案中，车辆可以在没有任何限制的情况下相互验证，例如需要签名者组、在线路侧单元 (RSU)、一组伪身份和防篡改设备。此外，我们的模拟表明，所提出的方案设计良好且有效。
