Trusted distributed identity authentication method and system, storage medium and application

Abstract

The invention belongs to the technical field of information security authentication, and discloses a trusted distributed identity authentication method and system, a storage medium and application, and the method comprises the steps that: a digital identity application module is called to create a digital identity on a block chain; a request identity credential module is called to request a credential issuing party for a credential; the voucher issuing party calls a voucher issuing module to issue an identity voucher to the user; a user calls a privacy protection module to select attributes needing to be verified by an application party, encrypts the attributes in the identity credentials or constructs attribute certification by using different cryptographic technologies according to privacy requirements of different attributes of the user, and puts the processed credentials on a block chain; and the application side obtains the voucher processed by the user from the block chain, calls a verification module, verifies the attribute or attribute proof in the user voucher, and verifies whether the attribute of the user meets a condition or not. And while the identity privacy of the user is protected, the practicability of the digital identity authentication is improved, and the application range of the digital identity authentication is expanded.

Description

technical field [0001] The invention belongs to the technical field of information security authentication, and in particular relates to a trusted distributed identity authentication method, system, storage medium and application. Background technique [0002] At present: With the emergence and popularization of the Internet, traditional identities have another form of expression, that is, digital identities generated based on cryptographic algorithms. The evolution of digital identity has gone through three stages, namely: centralized identity, alliance identity, and distributed decentralized identity. In the traditional identity system based on PKI (Public Key Infrastructure), user identity data is controlled by a single centralized authority, and there are problems such as identity information leakage, unclear definition of data ownership, and loss of control of data subjects. At the same time, on the one hand, due to the scenario-based and fragmented user data, data sou...

Problems solved by technology

Cryptography technologies such as ordinary encryption cannot solve user privacy issues. It is a new challenge to find new cryptography technologies, establish credible distributed identity authentication, and realize authentication under the premise of protecting user information.
