Power distribution terminal authentication method, system and device, computer equipment and storage medium

Abstract

The invention relates to a power distribution terminal authentication method, system and device, computer equipment and a storage medium. The method comprises the following steps: acquiring main node information sent by a to-be-authenticated node corresponding to the to-be-authenticated power distribution terminal; determining a main node corresponding to the main node information, and receiving a storage position sent by the main node; obtaining first terminal attribute information in the storage position, and obtaining second terminal attribute information sent by the to-be-authenticated node; and comparing the first terminal attribute information with the second terminal attribute information, and determining whether the identity authentication of the to-be-authenticated node is passed or not according to a comparison result. In the embodiment of the invention, any authenticated node in the private chain network can perform identity authentication on the node to be authenticated, so that identity authentication on a large number of power distribution terminals by depending on limited central trusted equipment can be avoided, the authentication speed is improved, and meanwhile, the timeliness of an authentication system caused by failure of single central trusted equipment can be prevented, therefore, the identity authentication efficiency of the power distribution terminal is effectively improved.

Description

technical field [0001] The present application relates to the technical field of power grids, in particular to a power distribution terminal authentication method, system, device, computer equipment and storage medium. Background technique [0002] With the development of power grid technology and the continuous advancement of distribution automation construction, the number of power distribution terminals put into operation has exploded, and the covered area has expanded rapidly. brought hidden dangers. In order to ensure the safe operation of the distribution automation system, the distribution terminals connected to the distribution automation system can be authenticated. [0003] In related technologies, the authentication function corresponding to the power distribution terminal certificate authority can be centrally deployed on a central trusted device, and the central trusted device performs identity authentication on the connected power distribution terminal.

Problems solved by technology

[0004] However, in the above method, only one central trusted device authenticates the power distribution terminal, and when there are many power distribution terminals that need to be authenticated, the authentication process will take a long time, which cannot meet the real-time requirements of the power distribution automation system. security requirements, and once a single central trusted device fails, it will easily lead to the failure of the entire authentication system

Therefore, the related technology has the problem of low efficiency of power distribution terminal identity authentication
