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

Abstract

The application discloses a double encryption-based service data processing method for a power distribution terminal. According to the method, received massages are processed by means of IPSec protocol authentication and decryption, and an identity authentication operation and a data decryption operation are performed at an application layer, so that data is prevented from being leaked, a power distribution system network is not maliciously invaded, the messages received by the power distribution terminal are sent by safe equipment, and the situations such as malicious attacks caused by data communication between masquerading equipment and the power distribution terminal can be avoided. The dual protection of a network layer and the application layer is realized in a process of service data processing of the power distribution terminal, so that the security protection performance of the power distribution terminal is improved, and the situations of the malicious attacks are avoided. The application also discloses a data encryption method of the power distribution terminal, a service data processing system, a data encryption system, the power distribution terminal and a computer readable storage medium, which have the 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...
