Electric power Internet of Things cross-domain authentication method based on cross-chain technology

Abstract

The invention discloses an electric power Internet of Things cross-domain authentication method based on a cross-chain technology. Each power Internet of Things terminal belongs to an authentication domain where the power Internet of Things terminal is located. Each authentication domain maintains an authentication block chain; an electric power Internet of Things system deployed in an edge Internet of Things proxy server maintains a public authentication block chain. Cross-domain authentication between the authentication domain and the public authentication block chain comprises three processes of registration, cross-domain authentication and cross-domain access. According to the method, the characteristic that the block chain cannot be tampered is utilized, so that safe and credible cross-domain transmission of the authentication data is guaranteed, the authentication server is deployed on the edge side, cross-chain transaction is performed through the edge Internet of Things agent,and the system operation efficiency and safety are guaranteed.

Description

technical field [0001] The invention relates to the security field of the electric power Internet of Things, in particular to a cross-domain authentication method for the electric power Internet of Things based on cross-chain technology. Background technique [0002] The power Internet of Things is an information system that fully applies modern information and communication technology to realize the interconnection of terminals and main stations in each link of the power system and human-computer interaction. It has the characteristics of comprehensive state perception, efficient information processing, convenient and flexible application, etc. It plays an important role in application scenarios such as electricity sales service, distributed power generation, new energy grid connection, and smart charging piles. [0003] With the development of information and communication technologies such as 5G, the power Internet of Things has developed rapidly in terms of terminal func...

Problems solved by technology

[0004]In the traditional power Internet of Things system, the credibility guarantee of the access terminal mainly depends on the centralized key management. Once there is a loophole in the key system, it will cause the entire system to security crisis

With the continuous development of distributed power sources, controllable loads, incremental distribution networks, and material services, the data transmission distance and data volume of IoT terminals are increasing rapidly, and comprehensive services that require cross-domain data sharing are emerging. The access authentication method can no longer meet the trust requirements of cross-domain business systems involving multiple parties such as the interaction of source, network, load and storage in the power Internet of Things, and accurate supply of materials.
