抗侦测的工业互联网:隐蔽通信技术的应用

Detection-Resistant Industrial Internet:Applications of Covert Communication Technologies

工业互联网是我国制造强国建设的关键支撑,是网络强国建设的重要基石,而保障工业互联网的安全是工业互联网稳步发展的先决条件。隐蔽通信技术具备隐藏保密信息传输行为的能力,具有良好的抗侦测性能,是我国工业互联网中其他信息安全支撑技术的有力补充,对于我国工业互联网安全保障机制的完善具有潜在的应用价值。本文首先基于现行工业互联网体系架构,分析了工业互联网的安全需求,提出应用隐蔽通信技术解决现有安全防护缺陷;分别从工业互联网中的网络安全与设备安全两层面介绍了隐蔽通信的具体实现方法,主要包含网络层隐蔽通信技术、链路层隐蔽通信技术、物理层隐蔽通信技术及行为隐蔽通信技术;最后,从完善工业互联网安全体系架构、突破隐蔽通信关键技术壁垒、推动隐蔽通信与现有安全技术融合三方面给出工业互联网安全的发展建议与隐蔽通信技术的应用展望。

Industrial Internet is the key support for the construction of manufacturing power and the important cornerstone for the construction of network power of China.Ensuring the security of the industrial Internet is a prerequisite for the steady development of it.Covert communication technology has the ability to hide confidential information transmission behavior and has great detectionresistant performance.It is a powerful supplement to other information security support technologies in China’s industrial Internet,and has potential application value for the improvement of China’s industrial Internet security mechanism.This paper firstly analyzes the security requirements of the industrial Internet based on the current industrial Internet architecture,and proposes to apply covert communication technology to solve the existing security defense defects.It also introduces the specific implementation of the covert communication from two aspects of network security and device security in the industrial Internet.The methods mainly include network-layer technology,link-layer technology,physical-layer technology and behavior covert communication technology.Finally,from the three aspects of improving the industrial Internet security system architecture,breaking through the key technical barriers of covert communication,and promoting the integration of covert communication and existing security technologies,the development suggestions for industrial Internet security and the application prospect of covert communication technology are given.
