Problems solved by technology
[0003] Although the above-mentioned system partially embodies the user-centered identity management model, it lacks technical support for the physical information network scenario where people, machines, and things are integrated, and does not consider multiple entity identities such as physical device identification, information object identification, and virtual object identification. Management architecture, lack of solutions in terms of information storage involved in identity management

Embodiment Construction
[0020] In order to make the objectives, advantages and technical solutions of the present invention more clear, the present invention will be further described in detail below through specific implementation and in conjunction with the accompanying drawings.
[0021] for figure 1 It describes the overall framework of the implementation of the program as a whole, mainly including the following five parts.
[0022] 1. URI-based unified description of multiple entity identities
[0023] Based on the hierarchical structure and unique characteristics of the Uniform Resource Identifier URI, multiple entity types such as user entities, terminal equipment entities, and virtual object entities are encoded. The specific encoding scheme is as follows: The structure of the URI identification system is mainly composed of management domain identification, type The management domain ID is expressed as Domain ID, the type ID is expressed as Class ID, and the entity ID is expressed as Entity ...

The invention discloses a multielement entity identity certificate information storage method which comprises the steps of 1) encoding a multielement entity by adopting a uniform identification structure URI; and 2) registering the uniformly described multielement entity to a URI identification service provider URI-IdP, and obtaining and storing an identity certificate of the entity, namely presetting a value region of a consistent hash ring (CHR), determining a position of a node K in the CHR based on a hash algorithm, setting the URI of the entity E as URI: / / AAA / BBB / CCC / DDD, dividing the value region into N sub regions corresponding to storage nodes, establishing a mapping list from the sub regions to the storage nodes for the CHR, calculating a storage node corresponding to the identity certificate of the entity E, and if the identity certificate of the entity E corresponding to URI: / / AAA is stored on the node K, determining that other pieces of entity information starting with URI: / / AAA are also stored on the node K.
Description
technical field [0001] The invention belongs to the field of identity identification in information security, and in particular relates to a method for storing multi-entity identity credential information. Background technique [0002] With the rise of new-generation information technologies such as cloud computing and the Internet of Things, traditional information-based identity management systems such as PKI based on X. There is an increasing gap between evolution and other aspects and actual security requirements. In recent years, some scientific research institutions and organizations have proposed relevant solutions for the above-mentioned informatization development trend. OpenID is a decentralized online identity authentication system proposed by the LiveJournal organization. It uniquely identifies and authenticates network users through the Uniform Resource Identifier (URI). Its core idea is to combine identity management, verification and identification functions ...
