Embodiment Construction

[0050] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0051] Such as figure 1 Shown: In order to effectively realize covert communication in the industrial Internet and ensure the safe transmission of industrial data in open wireless links with permeable borders, the covert communication method of the present invention includes the following steps:

[0052] Step 1, providing a covert communication transmitter and a covert communication receiver capable of communicating with the covert communication transmitter using a 5G network;

[0053] Specifically, the covert communication transmitter and the covert communication receiver can adopt existing commonly used forms, and the specific structural form can be selected and determined according to actual needs, as long as the covert communication transmitter and the covert communication receiver can use the 5G network to communicate. .

[0054] Generally, the covert co...

Abstract

The invention relates to an industrial Internet covert communication method and system. The method comprises the following steps: step 1, providing a covert communication transmitting end and a covertcommunication receiving end; step 2, transmitting a transmitting end IP data packet into a transmitting end steganography buffer through an MAC transmission block generated by media access control ina transmitting end 5G protocol stack; 3, reading the MAC transmission blocks in the steganography buffer of the transmitting end, and modulating the industrial confidential data into the number of RLC PDUs of the read MAC transmission blocks; step 4, sending the steganography data flow in the emission physical layer to a covert communication receiving end through a 5G network channel; 5, enablingthe covert communication receiving end to receive the steganography data flow through a 5G network, and obtaining an MAC transmission block according to the steganography data flow entering a 5G protocol stack of the receiving end; and step 6, enabling the covert communication receiving end to analyze and recover the industrial confidential data according to the read MAC transmission block. According to the invention, safe transmission of industrial data in a boundary permeable open wireless link is ensured.

Description

technical field [0001] The present invention relates to a covert communication method and system, especially a covert communication method and system for the industrial Internet, specifically a covert communication method and system for the industrial Internet based on the 5G wireless link control protocol, which belongs to the technology of network information security field. Background technique [0002] The Industrial Internet is a basic network that connects equipment, materials, personnel, and information systems to achieve comprehensive perception, reliable transmission, and real-time analysis of industrial data, forming scientific decision-making and intelligent control, and improving the efficiency of manufacturing resource allocation and production management. Among them, as the core system of the Industrial Internet, intelligent production management mainly involves the collection, transmission, analysis, processing, and decision-making control of important industr...
