车载自组织网络(VANET)实体之间的无线通信通过密码保护，该密码用于身份验证以及确保该环境中消息的整体安全性。身份验证协议扮演着重要的角色，因此要求不存在允许实体模拟、未经授权进入和系统的一般误用的漏洞。足智多谋的对手可以通过这样的漏洞对VANET系统造成严重破坏。我们考虑了文献中的几种VANET身份验证协议，并发现了漏洞。除了通常认为的VANET中的漏洞外，我们还观察到在几乎所有的VANET认证协议中都可能存在经常被忽视的中继攻击。通过虚报车辆身份、远程信息处理数据、与交通相关的警告以及与此类网络中的整体安全相关的信息，中继攻击有可能对VANET造成损害。我们讨论了解决已识别的漏洞的可能对策。然后，我们开发了一种身份验证协议，该协议使用环境条件来防止中继攻击和其他考虑到的漏洞。我们为所提出的协议提供了安全证明。
Wireless communication among vehicular ad hoc network (VANET) entities is secured through cryptography, which is used for authentication as well as to ensure the overall security of messages in this environment. Authentication protocols play a significant role and are therefore required to be free of vulnerabilities that allow entity impersonation, unauthorized entry, and general misuse of the system. A resourceful adversary can inflict serious damage to VANET systems through such vulnerabilities. We consider several VANET authentication protocols in the literature and identify vulnerabilities. In addition to the commonly considered vulnerabilities in VANETs, we observe that the often-overlooked relay attack is possible in almost all VANET authentication protocols. Relay attacks have the potential to cause damage in VANETs through misrepresentation of vehicle identity, telematic data, traffic-related warnings, and information related to overall safety in such networks. We discuss possible countermeasures to address identified vulnerabilities. We then develop an authentication protocol that uses ambient conditions to secure against relay attacks and other considered vulnerabilities. We include security proof for the proposed protocol.
