Marvin M Theimer, David A Nichols, Douglas B Terry: Method for delegating access rights through executable access control program without delegating access rights not in a specification to any intermediary nor comprising server security. Xerox Corporation, Alexander E Silverman, July 15, 1997: US05649099 (280 worldwide citation)

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 ser ...
