Research on the security sharing method of power grid dispatching control data based on Alliance Blockchain and Zero-Knowledge Proof technology

With the widespread application of power system digital technology and the advancement of dispatch control cloud construction, the development of power grid regulation business presents the basic characteristics of many business participants, frequent business interactions, and large data exchange. The alliance chain technology in blockchain technology has become an important basis for the research of this paper because of its native support for multi-party business scenarios. Based on the alliance blockchain technology, this paper designs a multi-channel data isolation scheme for the grid dispatching control business to achieve efficient data sharing within a controllable range. At the same time, in order to ensure the security of the private data in the grid dispatching control business in the business interaction process. Furthermore, this paper designs a business interaction process for private data based on the zero-knowledge verification algorithm. Combined with smart contract technology, it automatically completes the entire network verification process of data encryption and zero-knowledge credentials, and realizes data security interaction in secret scenarios.
