Decentralized identity management method in D2D scene in 5G environment

Abstract

The invention discloses a decentralized identity management method in a D2D scene in a 5G environment, and the method comprises the steps that a data holding mechanism logs in a data use mechanism byadopting a DID, and obtains that an application needs the data holding mechanism to provide a certain verifiable declaration; the data holding institution authorizes the data using institution to obtain a verifiable statement from the identity center; and the data holding mechanism successfully logs in the data using mechanism. The method further comprises an identity information registration step: the user uses a 5G device DID program to create own DID; the user obtains an identity authentication mechanism list in the DID program; the user submits a verifiable declaration application to a specified identity authentication mechanism and provides a related verification material; after the identity certification institution audits the material, a verifiable statement is issued to the user, and the user becomes a data holding institution. Within the range covered by the same identity platform, the identity recognition and detection standards of the user are unified, the application permission and the user identity / data are separated from the data permission, and the ownership of the user data is guaranteed.

Description

technical field [0001] The invention relates to an identity authentication method, in particular to a method for decentralized identity management in a 5G environment D2D scene, and belongs to the field of computer technology. Background technique [0002] At present, based on the technology of direct data exchange between adjacent devices in the communication network of D2D (device to device) technology, the D2D communication link is established, and the transmission data does not need to be transferred by core equipment or central equipment, and can be directly passed through point-to-point decentralized The method is data transmission and mass terminal access network. The standardization organization 3GPP has listed D2D technology as the development framework of the new generation mobile communication system and has become one of the key technologies of the fifth generation mobile communication. It is a solution to ensure the trustworthiness and controllability of digital...
