Abstract
Systems and methods are provided for resource access control in computer systems. Our approach includes new techniques for composing and authenticating principals in an access control system. Our principals may comprise information that identifies the role of the user of a computer system, the mechanism by which the user was authenticated, and program execution history. Thus, when a principal makes a request, access control determinations can be made based on the principal's identity. Access control lists may provide patterns that are used to recognize principals, thereby ensuring a level of security without enumerating precise identifiers for all of the possible principles that may request a particular resource.
