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 processing devices. For edge gateway devices not very suitable

2. There is also security encryption realized by blockchain technology, through the encryption of relevant blocks on the chain, the effective protection of the block information is realized, but this type of method is not very effective in processing misjudgment information of trusted devices , and the judgment of the operating data is relatively independent, without forming an overall judgment

3. Some are encrypted by hardware devices, but for edge gateway devices that need to process a large number of sensors, installing corresponding security hardware on each sensor has limitations on cost

And on the whitelist mechanism, it is impossible to dynamically screen whitelist members
