CAMBRIDGE MASS CENTER FOR RESEARCH IN COMPUTING TECHNOLOGYAccess Control Models,Popek,Gerald J.

A model, its theoretical basis, and algorithms that construct optimum representations of access control relationships for a number of conditions are presented. The issue of reliability in the control of access to information in a shared data base is also discussed. Author
