In recent years, with the development of new technologies such as artificial intelligence, big data, cloud computing and the like, network space security faces new security challenges, and some malicious attacks have the characteristics of long-term concealment, diversified expression forms, diversified technologies, infiltration intellectualization and the like, so that new potential safety hazards are brought to the network space. As a basic research of credible authentication between network space entities, the identity management technology is used for generating, registering, checking and the like the digital identities corresponding to the entities, verifying whether the identities claimed by the entities are real or not, and ensuring that the entities are the legal owners of the digital identities. The identity management technology is related to the safety of the whole system, and according to the data leakage survey report of 2018 of Verizon, 81.1 percent of safety events are related to identity management, and activities such as identity stealing, damage and identity counterfeiting are increasingly frequent, so that the identity management has a very important role.
The complexity of digital identities determines the need for effective measures to manage, and there are many digital identity management models, including independent models, centralized models, federation models, and user-centric models, as well as the Self-identity (SSI), which is a new stage of digital identity development in recent years. The traditional centralized identity information management mode is easy to cause that a central identity database becomes a system value core, often becomes a target of adversary attack, causes single-point failure, causes the situations of user identity information leakage, identity embezzlement and the like, for example, in recent years, a large amount of user identity information of companies such as yahoo, LinkedIn, Equifax, Facebook and the like is leaked, and the continuously-occurring events fully indicate that the user lacks autonomous control and ownership in the aspect of digital identity.
The existing identity management technology mainly has the following defects:
1) centralized processing nodes, such as identity databases, identity access control rule bases, and other important digital assets or control nodes, exist in identity management information systems. The central nodes are easily attacked by viruses, trojans, DDOS and the like inside and outside the network of the information system, so that single-point failure faults are caused, the central nodes are down, and the whole system stops working.
2) Various entities (people, intelligent equipment and the like) cannot own and control own identity data, and the identity data of the entities is easy to modify and steal.
