In the advanced technological world, vehicular communications are used in numerous business and safety applications for smart traffic management. With the help of vehicle-to-vehicle (V2V) communication, users can transfer substantial information directly to the reachable vehicles. Generally, the movement of vehicles on the highway is faster than crossroads, thus, to communicate securely and efficiently, a robust vehicular communication system is required. Therefore, a number of message dissemination protocols have been designed by the researchers, but distinct interests (i.e, storage cost, high communication overhead, more execution time, and security threats) are sought in these systems, which lead toward unreliability for on-the-fly communication. Very recently, Limbasiya-Das ( Ieee System Journal , pp 1937–9234, 10.1109/JSYST.2019.2932807) introduced a hash-based secure and efficient V2V data dissemination protocol to transfer significant information at the receiver end. Limbasiya-Das claimed the security of their protocol against numerous security attacks. However, in this comment, we highlight the loopholes of Limbasiya-Das protocol and show that their protocol is vulnerable to impersonation attack. Moreover, it has irrelevant usage of timestamp and does not offer user's anonymity. In addition, it lacks message confidentiality because an adversary can determine and view the messages exchanged among the legitimate vehicles by intercepting the messages disseminated over public channel. Finally, we provide probable remedy to mitigate the deficiencies of Limbasiya-Das protocol.

关于“车对车通信的轻型安全消息广播协议”的评论

在先进的技术世界中，车辆通信已在众多业务和安全应用中用于智能交通管理。借助车对车（V2V）通信，用户可以将大量信息直接传输到可及车辆。通常，高速公路上的车辆运动比十字路口快，因此，为了安全有效地进行通信，需要鲁棒的车辆通信系统。因此，研究人员已经设计了许多消息分发协议，但是在这些系统中寻求了不同的兴趣点（即存储成本，高通信开销，更多的执行时间和安全威胁），这导致了不可靠的消息传递协议。飞行交流。最近，Limbasiya-Das（ 依爱系统杂志 ，第1937–9234页，第10.1109 / JSYST.2019.2932807页）引入了一种基于哈希的安全有效的V2V数据分发协议，以在接收器端传输重要信息。Limbasiya-Das声称其协议的安全性遭到了许多安全攻击。但是，在此评论中，我们强调了Limbasiya-Das协议的漏洞，并表明它们的协议容易受到模拟攻击。而且，它与时间戳的使用无关，并且不提供用户的匿名性。另外，它缺乏消息机密性，因为对手可以通过截获通过公共渠道传播的消息来确定并查看合法车辆之间交换的消息。最后，我们提供了可能的补救措施来减轻Limbasiya-Das协议的不足。
