Abstract
The massively connected 5G IoT scene brings new challenges to identity authentication. Existing identity authentication methods have problems such as high time delay and poor efficiency when mass access is performed, and it is difficult to meet the situation of the rapid increase in the number of users. In this paper, we proposed a blockchain-based user identity authentication method for 5G IoT scenarios. This method builds the mapping relationship between user attributes and identity, and utilizes blockchain technology to realize the authentication requirements of mass users in 5G scenarios. In addition, we also deployed a prototype system to verify the performance of the proposed method. Experimental results show that the identity authentication method proposed in this paper has significant advantages in delay and processing efficiency compared with traditional centralized authentication methods and common distributed authentication methods.
