摘要
通信双方修改某类共享资源且不引起其他用户注意的通信方法被称作隐蔽通信,而区块链作为一种去信任、可溯源、不可篡改的分布式数据共享技术平台,伴随着相关领域拓展的同时也出现了基于区块链构建隐蔽通信的技术探索,该方向历经近几年的研究已被证明其可行性。首先介绍了隐蔽通信相关概念与技术分类;然后结合现有研究成果将区块链隐蔽信道按照构建原理分为基于区块结构、基于外部载体、基于业务操作时间和基于系统机制四类,详细梳理了各类技术特点,并针对各类隐蔽信道介绍了相应的检测方法;最后展望了区块链隐蔽通信构建技术及其检测方法的发展趋势,旨在为相关研究提供一定的参考价值。
The communication method in which both parties could modify certain types of shared resources without attracting the attention of other users was called covert communication.As a detrusted,traceable and tamper-resistant distributed data sharing technology platform,blockchain and related technologies have been explored to build hidden communication with the expansion of relevant fields.The feasibility of this direction has been proved through research in recent years.The related concepts and technology classification of covert communication technology were introduced,and then the blockchain covert channel was divided into block-based structure,external carrier,business operation time and system mechanism based on the existing research.Various technical characteristics were sorted out in detail,and corresponding detection methods were introduced for various types of covert channel.Finally,the future development trend of the hidden communication and detection method of blockchain were explored,which could provide certain reference value for relevant research.
