Communication security maintenance device based on power edge gateway equipment

Abstract

The invention provides a communication security maintenance device based on power edge gateway equipment, and relates to the technical field of electrical equipment. The device comprises a hardware part and a software part, wherein the hardware part comprises an encryption identification unit and communication interface equipment thereof, and is used for carrying out information reading, white list qualification comparison and pre-classification on communication data transmitted by lower-layer equipment, and is in data connection with a software port; and the software part comprises a basic discrimination module, a periodic white list equipment inspection module and an information detection and fault discrimination module. According to the invention, on the basis of a machine learning algorithm and hardware encryption feature coding information, unique identification and security evaluation of the bottom sensing device are realized, periodic white list updating is arranged, and the security requirement of the whole device data transmission process is met. And on the basis, a function of realizing multi-gateway matrix type auxiliary security evaluation in the edge gateway at the same level is designed, so that the purpose of improving the judgment accuracy is achieved.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a maintenance communication security device based on an electric edge gateway device. Background technique [0002] Under the premise of increasing communication speed, processing equipment tends to be more and more intelligent and portable, which brings about the rapid development of Internet of Things technology. The interconnection of smart devices also promotes the rapid development of smart grid-related devices, but what follows is an increasingly large amount of data and more types of communication requirements. Under this premise, the edge gateway device of edge computing and bearer technology, a processor layout method with better information extraction ability and faster data processing feedback speed began to emerge, but this also brought about the Certain threat to security. [0003] Most of the information transmission process of the traditional power g...

AI Technical Summary

Problems solved by technology

For data transmission: 1. In terms of data uplink channels, for a large amount of sensor device data, information may be maliciously replaced or maliciously blocked, resulting in omissions and omissions in data judgment

2. In terms of data downlink, there may be a large number of abnormal instructions for the equipment, causing the next-level equipment to enter a temporary out-of-control state, interfering with normal operation

Among the current processing methods: 1. Most of the mutual authentication and information encryption between sensors and edge gateways are realized through computational encryption, but such methods generally have relatively high complexity and have certain requirements for the computing power of process...
