Embodiment 1

[0045] This embodiment will further describe and explain the scheme adopted by the present invention:

[0046] Determine the identity information that the user needs to submit according to the user's request: According to the entity information that the user wants to access, the entity resource access will give a security degree of information to improve the security of identity authentication. If the user wants to access the entity resource, he needs to provide himself Identity information is authenticated. At this time, in order to achieve the authentication security of entity access in the authentication process, according to the availability of user identity information, multiple sets of authentication combinations will be generated according to the credibility of user identity information, and a set of identity The information is authenticated, and the credibility of the identity combination information is the weighted sum of the credibility of each identity information. ...

Embodiment 2

[0050] Below in conjunction with specific data, the present invention is further elaborated, the identity authentication process that the present invention adopts is as follows figure 2 shown, including the following steps:

Abstract

The invention belongs to the technical field of information security, and particularly relates to a multi-granularity joint identity authentication method for an identity alliance. The method comprises the following steps: researching the credibility of various identity information using the credibility as a multi-granularity joint weight of the various identity information; with the minimum costas a constraint condition, performing multi-granularity joint identity authentication for user demands and identity authentication for user identity information availability; and when a user proposesan access demand, performing, by the identity alliance, evaluation and screening on an identity authentication scheme according to the demand of an application system on the identity authentication security, so that the safety and reliability of the identity authentication are improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a multi-granularity joint identity authentication method oriented to identity alliance. Background technique [0002] As network applications and Internet services penetrate into every aspect of people's lives. While the network brings convenience to people, it also brings huge security risks. In particular, the virtuality of network identities brings new challenges to commercial credit, national security and social stability. Identity federation is the development trend of identity management in large-scale heterogeneous networks in the future. In identity federation, a service provider accepts identity information and authentication operations maintained by another identity provider based on its own efficiency and economic considerations in order to enable users to securely access its services. Identity federation provides users with a simple identity...
