Embodiment Construction

[0081] Below in conjunction with accompanying drawing and example the present invention is described in further detail.

[0082] The present invention is a solution method based on zchaff's RBAC system user authorization query request problem, the user can create requirements according to the state of RBAC in the system and the authorization query request problem, and can also set up corresponding security constraints, expected authority quantity targets and expected roles quantity target. With good flexibility and friendly user interface, it is convenient for users to use and modify data.

[0083] At first provide several concepts in the present invention:

[0084] Role-based access control RBAC (Role‐based Access Control) model: In the RBAC model, the concept of roles is introduced between users and permissions. Users can be assigned multiple roles, and roles can also be assigned multiple permissions. Users pass The role indirectly obtains the corresponding permissions. T...

Abstract

The invention provides a fast solution method for user authority query request problems of an access control system, which is applied to the field of access control. The fast solution method comprises the following steps of introducing zchaff into a RBAC (role-based access control) system; firstly, reducing the scale of the to-be-considered request authority through static clipping; then, reducing the number of roles not containing the request authority through preprocessing; finally, converting the problem, the RBA (role-based access) system state and the safety constraints into a conjunctive normal form, and calling a SAT (satisfiability) solver zchaff, so as to obtain the high-efficiency computation efficiency. The quick solving method has the advantages that under the condition of existing RBAC system state, the high solving efficiency is provided for the user authority query request problem, the security is guaranteed, and the extendibility is better.

Description

technical field [0001] The invention relates to the field of access control, in particular to a method for quickly solving the user authorization query request problem of an RBAC system based on zchaff. Background technique [0002] The rapid development of network and information technology allows us to share resources and services through network applications, effectively improving the utilization of data. However, the characteristics of the network itself, such as openness, anonymity, and data transmission transparency, pose many new challenges to ensuring the confidentiality and integrity of information, which seriously hinders the further popularization and application of network technology. Access control is one of the most important core technologies to ensure network security. It allows authorized subjects to access certain objects, and at the same time refuses to provide services to unauthorized subjects. [0003] The concept of role-based access control RBAC (Role...
