Abstract

The invention discloses an ordering policy authorization method and system for extended xacml access control. The method comprises the following steps of: S1, defining and generating an access policy;S2, defining and generating a management policy and obtaining a policy library; S3, carrying out ordering on policies in the policy library according to level values from big to small; S4, submittingan access request to a pdp (Policy Determination Point) of an xacml access framework; and S5, searching the ordered policy library, and returning a determination result of a policy with the maximum level value. By the ordering policy authorization method and system disclosed by the invention, search efficiency of the authorized policy can be improved.

Description

technical field [0001] The invention relates to the field of network space security, in particular to a sorting strategy authorization method and system for extending xacml access control. Background technique [0002] In the field of information security, access control management is a method of managing resource access based on user identities, and authorization is a flexible access management mechanism, which means that users can transfer their access rights to specific resources to other entities. Most of the existing authorization mechanisms are based on the role-based access control (RBAC) model, which grants access rights to roles for authorization, and a few models are based on the authorization of the attribute-based access control (ABAC) model. [0003] XACML v3.0 Administration and Delegation Profile Version 1.0, 2014 describes an authorization mechanism based on the xacml standard, which accesses the request by searching the authorization policy <issuer>At...
