Abstract
Access to a resource may be controlled by a policy, such that a request to access the resource is either granted or denied based on what assertions have been made by various principals. To find the assertions that support a grant of access to the resource, a template may be created that defines the nature of assertions that would cause access to succeed. Assertions may be stored in the form of tokens. The template may be used to search an existing token store to find assertions that have been made, and/or to generate assertions that have not been found in the token store and that would satisfy the template. The assertions in the template may be created by performing an abductive reasoning process on an access query.
