Credible identity authentication method based on block chain

Abstract

The invention discloses a trusted identity authentication method based on a block chain. A blockchain certificate server transmits trust through a cross-domain model based on a block chain and realizes an authentication process of a client and an information service entity in different trust domains, and the information service entity obtains a complete signature through an arbitration entity communication server and realizes authentication of the complete signature through an identity authentication server. Only partial keys are stored in the information service entity; the rest secret keys are stored in the arbitration entity communication server; the information service entity obtains a complete signature of the message through the arbitration entity communication server; according to the invention, the capability of revoking the decryption or signature of the arbitration entity communication server can be realized by stopping sending signaling through the arbitration entity communication serve , the problem that the entity identity in the IBC system is difficult to cancel is solved, the problems of many certificate checking times, low cross-domain authentication and the like are also solved, and the decentralization and higher security of the block chain system are ensured.

Description

Technical field [0001] The invention relates to the technical field of cyberspace security, and more specifically to a trusted identity authentication method based on blockchain. Background technique [0002] In a heterogeneous network environment, for users, due to the continuous expansion of the application domain of providing network resources and services, the information interaction between different application domains has become extremely frequent. In order to ensure that when users access network service resources in the same or different trust domains, they will not bring additional identity authentication overhead and burdens, and at the same time can achieve access control and authority management between different domains, then it is necessary to adopt a global-oriented approach The cross-domain identity authentication mechanism fundamentally prevents the risk of illegal access to network resources. Therefore, it is also very promising to study the cross-domain authe...
