Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a privacy protection-based cross-security domain access control system, and another purpose is to provide a privacy-based cross-security domain access control method. The present invention solves the problem of cross-security domain access control For the problem of privacy leakage of service requesters, the control method of the present invention is a strategic method. By using the technical solution provided by the present invention, the privacy protection of service requesters can be realized, the degree of information disclosure can be reduced, the disclosure of sensitive information can be prevented, and service requestors can be realized privacy security

Embodiment Construction

[0057] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] Based on the access control model, the privacy protection mechanism combines identity-based encryption technology to realize the privacy of cross-domain access control. This mechanism is divided into five parts: system initialization, authorization assignment, policy customization and response, encryption processing, message recovery and verification. This mechanism uses attribute Boolean variables to describe policy expressions, transforms policy expressions into disjunctive paradigms, and forms a mapping between access control decisions and policy Boolean expression values. The service provider encrypts the information with the policy implied in the public key, and the requester decrypts the message with the decryption key that implies the authorization assignment, and only if the requester has the private key c...

Abstract

The invention relates to a control system and method in the field of information safety, in particular to a cross-safety-domain access control system and method based on privacy protection. The control system comprises an authorization server, a service provider and a service requester. The control method includes that a privacy protection mechanism is adopted, fusion of cross-safety-domain access control and a privacy protection mechanism is finished in the processes of system initialization, authorization and assignment, strategy making, encryption processing and message recovery and verification, protection of privacy information of the requester is achieved, and the problem of privacy leakage of the service requester in the cross-safety-domain access control is solved. By means of the control system and method, privacy protection of the service requester can be achieved, information disclosure degree is reduced, sensitive information leakage is avoided, and privacy safety of the service requester is achieved.

Description

technical field [0001] The invention relates to a control system and a control method thereof in the field of information security, in particular to a privacy protection-based cross-security domain access control system and a control method thereof. Background technique [0002] With the rapid development and popularization of computer technology and network technology, multiple geographically dispersed organizations have realized remote dynamic interaction and collaborative work through computer networks, and network-based e-commerce, e-government, network scientific research and other activities have gradually become mainstream. application mode. The network-based cross-domain multi-organization large-scale information system application has the characteristics of openness, distribution, and dynamics, so cross-domain access control presents the characteristics of resource distribution, activity dynamics, and subject ignorance. . How to effectively control the resources o...
