AI Technical Summary

Technical Problem

When semantic communication is used for power data transmission, maintaining confidentiality through encryption or physical layer security systems is easy to make eavesdroppers aware of protection measures and adopt more complex attacks, resulting in low security of data transmission.

Method used

At the sending end of the semantic communication system, after obtaining semantic information, artificial noise is added to generate transmission semantic information. The artificial noise is generated by the artificial noise generation model to ensure that both the legal user and the potential eavesdropper can decode. The legal user decodes the image to be sent, and the potential eavesdropper decodes the image to be sent.

Benefits of technology

Through the use of artificial noise, the decoding results of potential eavesdroppers are misled, making them unable to detect protective measures, and at the same time, the accurate decoding results are retained for legitimate users, effectively improving the security of power data transmission in semantic communication technology.

Abstract

The invention discloses a semantic camouflage communication method and system, a power grid and electronic equipment, and relates to the technical field of power system safety. According to the method, semantic information extracted from a to-be-sent image by a semantic encoder of the semantic communication system is obtained at a sending end of the semantic communication system, and then a semantic information decoding module used for ensuring that both a legal user and a potential eavesdropper in a deployment environment of the semantic communication system can decode is added to the semantic information, and the legal user decodes to obtain the to-be-sent image, and the potential eavesdropper decodes to obtain the artificial noise of the disguised image, so as to obtain the transmission semantic information, pre-codes the transmission semantic information, and sends the pre-coded transmission semantic information. Therefore, the problems that when semantic communication is adopted to carry out power data transmission, confidentiality is maintained through encryption or a physical layer security system, an eavesdropper is easily aware of protection measures, and data transmission security is not high due to the adoption of more complex attacks are solved.
