Blockchain technology's popularity in terms of security, privacy, traceability, and trust is being applied in various major applications concerning connected autonomous vehicles. One of the most sensitive applications is military operations. We do not compromise with either security, privacy, trust, or communication latency of connected military vehicles, i.e., Internet of military vehicles (IoMVs). Achieving anonymity along with the security and privacy of sender, receiver, and data path for IoMVS is still an open question. Efforts we have made to address the aforementioned issue by proposing a blockchain-based onion routing protocol for IoMVs, i.e., B-IoMV, to achieve secure, trusted, and anonymous D2D communication. We studied the working of onion routing and presented a blockchain and token-based solution to strengthen the security and anonymity of IoMVs. A blockchain-based solution is quite costly and we use InterPlanetary File System (IPFS) to make the proposed B-IoMV system cost-effective. Finally, results show that the proposed B-IoMV system achieved better communication latency, data storage cost, and network bandwidth utilization.

区块链技术在安全性、隐私性、可追溯性和信任方面的普及正被应用于与联网自动驾驶汽车相关的各种主要应用中。最敏感的应用之一是军事行动。我们不会在联网军用车辆（即军用车辆互联网 (IoMV)）的安全性、隐私、信任或通信延迟方面做出妥协。实现匿名以及 IoMVS 的发送方、接收方和数据路径的安全性和隐私性仍然是一个悬而未决的问题。为了解决上述问题，我们提出了一种基于区块链的 IoMV 洋葱路由协议，即 B-IoMV，以实现安全、可信和匿名的 D2D 通信。我们研究了洋葱路由的工作原理，并提出了一个基于区块链和令牌的解决方案，以加强 IoMV 的安全性和匿名性。基于区块链的解决方案非常昂贵，我们使用星际文件系统 (IPFS) 使提议的 B-IoMV 系统具有成本效益。最后，结果表明，所提出的 B-IoMV 系统实现了更好的通信延迟、数据存储成本和网络带宽利用率。
