Power distribution automation equipment and data encryption and decryption method and system

Abstract

The invention discloses power distribution automation equipment. The to-be-processed data is encrypted and decrypted by utilizing the first encryption and decryption module or the second encryption and decryption module; due to the fact that the encryption and decryption module is used for completing encryption and decryption of the to-be-processed data, compared with the mode that software encryption and decryption are conducted on the to-be-processed data through a central processing unit in the prior art, occupation of a main CPU and memory resources is avoided, and the overall working efficiency of the power distribution automation device is improved. In addition, according to the target information, the corresponding encryption and decryption module can be selected and switched to complete encryption and decryption of the to-be-processed data; while occupation of a main CPU and memory resources is avoided, encryption and decryption on the data are more flexible, the data encryption and decryption security is higher, and the overall working efficiency of the power distribution automation equipment is further improved. In addition, the invention further provides a data encryption and decryption method and system, and the effects are shown above.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a distribution automation equipment, a data encryption and decryption method and system. Background technique [0002] In the power distribution network, the distribution automation equipment cooperates with the distribution automation master station or the distribution automation sub-station to realize the signal acquisition of multiple distribution network lines, the line switch control, and the detection, location and isolation of faults, etc. Features. In order to improve the security of information exchange between the distribution automation device and the distribution automation master station or distribution automation sub-station, the exchange information can be encrypted and decrypted by corresponding encryption means and encryption mechanism. [0003] At present, the encryption and decryption method for information exchange between distribution automation...

AI Technical Summary

Problems solved by technology

[0003] At present, the encryption and decryption method for information exchange between distribution automation equipment and distribution automation master stations or sub-stations is to use the central processor of distribution automation equipment to perform soft encryption and decryption. Using this method will occupy distribution automation The central processing unit and memory resources of the device will slow down other business processes of the distribution automation equipment and affect the overall work efficiency of the distribution automation device / equipment

[0004] At present, different regions (such as the State Grid and China Southern Power Grid) have different requirements for the Ethernet communication transmission function of the encryption chip, and different encryption and decryption schemes are required for different types of encryption chips (whether they have the Ethernet communication transmission function or not). , at this time, it is necessary to complete the encryption and decryption process with different distribution automation equipment, and the versatility and flexibility of distribution automation equipment are low
