Multi-dimensional Identity Authentication Mechanism for Power Maintenance Personnel based on Blockchain

In order to solve the problems of easy leakage of data and attacks when power maintenance personnel use mobile terminals for identity authentication, this paper proposes a multi-dimensional identity authentication mechanism for power maintenance personnel based on Blockchain. First, based on Blockchain technology, a cross-domain authentication model composed of multiple distributed independent domains and a Blockchain network is proposed. Secondly, the multidimensional identity model establishment process is designed in detail, including the identity model in the local domain and the identity model in the access domain. By analyzing and comparing the typical application process of the authentication mechanism in this paper, it is verified that the authentication mechanism in this paper achieves multi-domain security authentication on the basis of ensuring the security of authentication information, and avoids the threat of traditional authentication technologies vulnerable to attacks.
