Alliance trust distributed identity authentication method and system based on block chain

Abstract

The invention relates to an alliance trust distributed identity authentication method and system based on a block chain. The system comprises an alliance distributed identity account book, an alliancedistributed identity service node and a distributed identity client. The alliance digital identity account book is used for storing alliance distributed digital identity information of distributed heterogeneous network entities in the alliance; the alliance distributed identity service node receives a distributed identity client identity authentication and identity management request, and performs writing, query and marking operations on alliance distributed digital identities by means of the alliance distributed identity account book; and the distributed identity client provides local alliance distributed digital identity management for the distributed heterogeneous network entity, and stores the alliance distributed digital identity of the entity through an identity wallet built in theclient. According to the system, full-life-cycle management of registration, verification, updating and logout of the alliance distributed identity identifier is realized through the alliance distributed identity identifier management model.

Description

technical field [0001] The invention belongs to the field of identity authentication security in the field of information security, and in particular relates to a block chain-based alliance trust distributed identity authentication method and system. Background technique [0002] In recent years, with the rapid development of technologies such as the Internet of Things, Internet+, 5G, and big data, the information interaction among distributed heterogeneous network entities such as personnel and equipment in alliance organizations has been increasing, and the multi-party Increased demand for collaboration and data fusion. As the first pass to protect the security of distributed application information systems, identity authentication is becoming more and more important to achieve mutual trust between network entities through reliable identification of the identity information of each distributed network entity. However, due to the lack of interoperability of identity inform...

Problems solved by technology

[0006] The technology of the present invention solves the problem: Aiming at the requirement of identity authentication and intercommunication between distributed heterogeneous network entities in the alliance organization, and the traditional identity authentication scheme has more or less potential safety hazards, the present invention proposes an area-based The alliance trust distributed identity authentication method and system of the block chain, the system designs the alliance distributed digital identity with the alliance distributed identity identifier for the distributed heterogeneous network entities such as personnel, equipment, enterprises and organizations in the alliance, and adopts The alliance digital identity ledger stores the alliance distributed digital identity information of the distributed heterogeneous network entities in the alliance, and ensures the safe storage and safe sharing of the alliance distributed digital identities of the distributed heterogeneous network entities in the alliance through the consensus mechanism and privacy protection mechanism; and Through the alliance distributed identity identifier management model, the entire lifecycle management of the alliance distributed identity identifier registration, verification, update, and cancellation is carried out. The alliance distributed identity authentication operation mechanism model provides a secure cross- Domain Federation Trust Distributed Identity Authentication
