摘要
Disclosed are methods and devices for provisioning authorization claims, which are enforced to control access of users to objects (resources) in a computer system (330), and which are to be equivalent to an attribute-based access control (ABAC) policy. A policy converter according to the invention includes a policy processor (310) processing the policy by partial evaluation against attribute values of the users, objects or permission levels in the system and outputting simplified policies, which are subject to reverse evaluation in a reverse policy evaluator (320), whereby users, objects and permission levels to be associated by way of a single authorization claim are obtained. Responsible for the defining of the authorization claim and its distribution in the computer system are an authorization claim generator (330) and an authorization claim distribution interface (340). The invention may be so configured as to return a single authorization claim for each combination of an object and a permission level.
