Example Embodiment

[0039] Example

[0040] A grid-based multi-trust domain authentication system in a grid environment, including four modules: grid structure building module, trust domain management module, grid structure conversion module, and cross-domain access control module. Users communicate with this system through a user access interface. Interaction to achieve access to Internet resources;

[0041] The grid structure building module is the lowest module of the system, responsible for the unified management and organization of Internet network resources, realizing the call of the underlying network entities and applications, and the allocation and use of shared resources in the network. This module Construct a network structure organized in a grid;

[0042] The trust domain management module is based on the network structure organized in grid form constructed by the grid structure building module, divides and manages trust domains according to the trust domain management strategy, selects the...

Abstract

The invention relates to a multi- trust domain authentication system under a lattice-based grid environment, belonging to the field of information safety. The multi- trust domain authentication system comprises a grid structure constructing module, a trust domain management module, a lattice structure converting module and a cross domain access control module, and the working process comprises grid initialization, initialization within domain, initialization of an authentication server and user authentication. In the invention, each trust domain is an authentication entity, thus making the most of the resource sharing advantage of a grid model; when each domain is used as an authentication server, only the related authentication information by taking the domain as an upper bound domain ora lower bound domain needs to be stored, and the global authentication information needs not to be stored, thus reducing redundancy of information storage and facilitating maintenance and management;and in the authentication process, the authentication server of each domain is known, and the authentication path is relatively determined, thereby improving the cross domain authentication efficiency.

Description

technical field [0001] The invention relates to a multi-trust domain authentication system in a lattice-based grid environment, belonging to the technical field of information security. technical background [0002] The development of informatization construction and network technology makes information sharing more and more convenient, and the acquisition, transmission and processing of information in the network is more convenient, but the information has very sensitive security features to a certain extent, so how to It is very necessary to realize identity authorization and authentication across trust domains between different enterprises and applications. Access control, an information security technology that has been widely concerned in recent years, provides a solution to this problem and has attracted widespread attention from academic circles and business circles at home and abroad. [0003] Grid computing as infrastructure and next-generation network has also att...
