A business data processing method for power distribution terminals based on double encryption

Abstract

This application discloses a business data processing method based on double encryption for power distribution terminals. By performing IPSec protocol authentication and decryption processing on received messages, and then performing identity authentication operations and data decryption operations at the application layer, the data is kept Not to be leaked, to prevent the power distribution system network from being maliciously invaded, so that the messages received by the power distribution terminal are messages sent by safe devices, and to avoid malicious attacks such as masquerading equipment and power distribution terminals for data communication . In the process of processing the business data of the power distribution terminal, the double protection at the network layer and the application layer is realized, which improves the security protection performance of the power distribution terminal and avoids malicious attacks. The present application also discloses a data encryption method for a power distribution terminal, a business data processing system, a data encryption system, a power distribution terminal, and a computer-readable storage medium, which have the above beneficial effects.

Description

technical field [0001] This application relates to the technical field of power distribution automation, in particular to a double encryption-based business data processing method for power distribution terminals, a data encryption method for power distribution terminals, a business data processing system, a data encryption system, power distribution terminals, and computer-readable storage medium. Background technique [0002] With the continuous development of electric power technology, the automation system of distribution network has appeared, which improves the power distribution efficiency when the power grid is in use. The distribution automation system is based on the distribution master station and the distribution terminal, and the distribution network is connected between the distribution master station and the distribution terminal through a dedicated communication optical fiber to ensure the communication between the distribution master station and the distribut...

AI Technical Summary

Problems solved by technology

Malicious attackers can attack the public communication network, steal power-sensitive data to analyze the weak links of the grid, and even invade the main station through the terminal of the sub-station, control the front-end computer to forge remote control instructions, and eventually cause a large-scale power outage, causing serious destructive events

Generally, the encryption method provided by the prior art for public network data is based on specific encryption hardware to encrypt the data, but the encryption method provided by the prior art only encrypts the data at one level, the encryption effect is not good, and it is easy to be hacked. Malicious cracking

[0004] At the same time, even if the main distribution station and distribution terminal in the power distribution system are connected through a dedicated optical fiber network, if the data is not encrypted during transmission or the encryption processing effect is not good, the transmitted data is easily be obtained, thereby carrying out large-scale intrusions on the power distribution system, causing a wide range of security threats
