Abstract
A method in which access control programs (ACPs) permit controlled delegation of access rights from clients to untrusted intermediaries. ACPs are programs that encode arbitrary specifications of delegated access rights. In the method, a client creates an ACP and associates it with a request to a server, the request being made through one or more intermediaries. When processing a request received from an intermediary, the server executes the access control program to determine whether or not to grant the request.
