Communication method between power distribution automation master station and power distribution automation terminal

Abstract

The invention discloses a communication method between a power distribution automation master station and a power distribution automation terminal, which comprises the following steps: A, a group of private keys stored in the power distribution automation master station and a group of public keys stored in the power distribution automation terminal are generated; B, the power distribution automation master station encrypts a packaged message by adopting the private keys, and the power distribution automation terminal encrypts the packaged message by adopting the public keys; C, the power distribution automation master station uses the private keys to decrypt the encrypted message, and the power distribution automation terminal uses the public keys to decrypt the encrypted message. According to the communication method between the power distribution automation master station and the power distribution automation terminal provided by the invention, an illegal person cannot steal data ina communication process, so that the safety performance of communication of the power distribution network automation system is greatly improved, and the property safety of people is guaranteed.

Description

Technical field [0001] The invention relates to the communication field of distribution network automation systems, in particular to a communication method between a distribution automation main station and a distribution automation terminal. Background technique [0002] In December 2015, 1.4 million residents in parts of the Ukrainian capital Kiev and western Ukraine suddenly noticed a power outage at their homes. The outage was not due to power shortages but was attacked by hackers. The incident of Ukrainian power being hacked attracted the attention of global power companies. At the same time, the occurrence of such an incident made the staff of the power company unforgettable, and made human beings afraid. [0003] At the same time, with the vigorous development of the national smart grid technology, the scale of the distribution network automation system is also increasing. The coexistence of multiple communication methods and the communication method of all messages using pl...
