摘　　要：网络空间作为继陆海空天之后的第五大主权领域空间,是国际战略在军事领域的演进。网络空间中信息主导权的争夺,对军事通信的安全性、稳定性提出了更高的要求。以未来高对抗和高智能战场需求为出发点,以当前区块链和密码学技术最新研究成果为基础,设计了基于区块链的高可靠军事信息隐蔽传输协议HRBCCM。该协议以零知识证明混币合约函数参数的数据结构和合法性验证逻辑为设计基础,提出了隐蔽通信交易的构造和识别算法,将信息的嵌入和提取过程与混币合约运行原理进行完美融合,实现了高隐蔽性和安全性的信息传输。同时从鲁棒性、可靠性、不可追踪性及不可探测性四方面进行安全性分析,并且搭建了仿真测试环境,对HRBCCM的传输时间和隐蔽率进行了测试和评估。实验结果显示,与传统方案相比其隐蔽性提升了20%,传输效率提高了40倍。最后,结合未来战场强对抗和高智能化程度的特点,分析了HRCCM在平时公网条件下全球情报信息传输和战时紧急状态下可靠通信能力保障两个典型应用场景,凸显了协议的场景的适配性。Cyberspace,as the fifth largest sovereign domain space after land,sea,air,and space,is the evolution of international strategy in the military field.The competition for information dominance in cyberspace places higher demands on the security and stability of military communication.Based on the requirements of future high confrontation and high intelligence battlefield and the latest research results of blockchain and cryptography,we design a highly reliable military information covert communication model,i.e.,HRBCCM.Based on the data structure and verification logic of coin mixing smart contract,we design the construction and identification algorithm of parasitic transactions.The process of embedding and extracting information is perfectly integrated with the operational principles of coin mixing smart contract,which ensures high concealment and secure information transmission.We also conduct security analysis from four aspects:robustness,reliability,anti-traceability,and undetectability.A simulation testing environment was established to test and evaluate the transmission time and concealment rate of HRBCCM.The experimental results showed that concealment performance improved by 20%and transmission efficiency increased by 40 times.Finally,two typical application scenarios,i.e.,global intelligence information transmission under peacetime public network conditions and reliable communication capability guarantee in wartime emergencies,were analyzed,highlighting the adaptability of the protocol's scenarios.
