Multi-party trusted identity authentication method and system based on block chain

Abstract

The invention discloses a multi-party trusted identity authentication method and system based on a block chain, and belongs to the field of Internet identity authentication. The technical problem to be solved is to realize identity authentication of a user in a plurality of application systems based on the block chain, securely store the user information in the identity authentication process through the block chain and really and completely verify the user identity. The method comprises the following steps: an application system generates user attribute card information according to a received registration request, encrypts the user attribute card information and issues the user attribute card information to the block chain, wherein a plurality of application systems are provided, and the encrypted user attribute card information corresponding to each application system is stored in the block chain; each application system verifies the user identity based on the block chain. The system structurally comprises a block chain network, a client authentication module configured in a client and an application server authentication module configured in the application system. By adoption of the multi-party trusted identity authentication method and system, the real name information of the user is stored in the block chain securely and reliably, and the identity authentication of the user is implemented really and completely through the block chain.

Description

technical field [0001] The invention relates to the field of Internet identity authentication, in particular to a block chain-based multi-party trust identity authentication method and system. Background technique [0002] In the PKI system, the digital certificate of the third-party CA is a way to indicate the user's real name information. A digital certificate is a string of numbers that marks the identity information of all parties in the Internet communication. It provides a way to verify the identity of the communication entity on the Internet. A digital certificate is a digital signature issued by the Certificate Authority (CA). A file containing information about the owner of the public key and the public key. People can use digital certificates to identify each other on the Internet. CA certification is a centralized certification model. All application systems and users must trust the CA unconditionally, resulting in low certification efficiency and high certifica...
