Abstract

The invention provides a power distribution automation message encryption transmission method and system, a terminal and a storage medium. The power distribution automation message encryption transmission method comprises the steps that identity authentication of a power distribution main station on a power distribution terminal is completed by verifying a power distribution terminal equipment identification code; the message is symmetrically encrypted and the symmetrically encrypted secret key is asymmetrically encrypted to obtain an encrypted message and an encrypted secret key; and the encrypted message and the encryption key are marked with an equipment identification code of a sending end, and the encrypted message and the encryption key are sent to a target end. According to the invention, symmetric encryption and asymmetric encryption are combined, so that the transmission security of the message is ensured and the encryption efficiency is relatively high.

Description

technical field [0001] The invention belongs to the technical field of distribution automation, and in particular relates to a distribution automation message encryption transmission method, system, terminal and storage medium. Background technique [0002] Distribution automation technology is an important technology serving the transformation and construction of urban and rural distribution networks. Distribution automation includes feeder automation and distribution management systems. Communication technology is the key to distribution automation. At present, my country's distribution automation has carried out many pilot projects. The three-layer structure composed of distribution main station, substation and feeder terminal has been generally recognized, and optical fiber communication as the communication method of the backbone network has also been recognized. The realization of feeder automation can also be fully established on the basis of optical fiber communicati...
