Blockchain Based High Performance User Authentication in Electric Information Management System

User Authentication is essential in electric information management system where the operations should be controlled according to standard specifications. Traditionally the authentication is implemented by rule/rights definitions in the static database, which is difficult to manage and audit when there are a number of users and resources. Therefore, blockchain technology is introduced to facilitate user authentication considering its decentralized and security features. However, the performance of blockchain based authentication is relatively low compared with the centralized database. In this paper, we propose a high-performance user authentication framework for electric information management system based on multiple level structure and parallel computing. The proposed framework is implemented in a Provincial electric company of China State Grid. According to the experimental results, the proposed framework not only implements the blockchain based user authentication by also improves the system performance by 60% compared with the non-optimized system.
