Abstract
With the rapid development of industrial internet services, the integration of IT/OT has enabled the continuous expansion of network security boundaries and put forward higher requirements for platform application cross-domain identity authentication. Aiming at the insufficient security of existing user-centric identity authentication schemes, this paper proposes a distributed authentication scheme based on the consortium blockchain in industrial Internet platform. The solution analyzes its applicability to the Industry Internet Platform from three perspectives: network architecture, industrial Internet platform user identity control, and user privacy. It defines the identity composed of consortium ID and consortium digital identity credentials, and builds distributed authentication architecture. The consortium blockchain is used to record the digital identity information of the industrial Internet platform users, and the consortium ID and the consortium digital identity credential are designed to realize the industrial Internet platform business securely access.
