Trusted Identity Authentication Mechanism for Power Maintenance Personnel Based on Blockchain

In order to solve the problem of impersonation of the electronic identity of power maintenance personnel, this paper proposes an trusted identity authentication model based on Blockchain. This model uses plug-in authentication technology to improve the scalability of the identity authentication system. In order to improve the usability of the authentication model, smart devices are named uniformly, and information such as names and corresponding parameters are registered on the distributed data trusted chain through smart contracts. In order to improve the practicability of the model, based on the model architecture, the registration process, login authentication process, and trusted identity card system architecture were designed. In terms of the architecture of the trusted identity system, it includes a Blockchain server, an authentication server, and a mobile terminal. Through the performance analysis, the authentication mechanism proposed in this paper is verified, which effectively solves the problems of poor reliability and centralized storage that easily lead to information leakage in traditional identity authentication.
