Abstract : CAMBRIDGE MASS CENTER FOR RESEARCH IN COMPUTING TECHNOLOGYAccess Control Models,Popek,Gerald J. ;F19628-70-C-0217AF-2801ESDTR-73-106(*data processing, networks), computer programming, mathematical logic, mathematical models, mapping(transformations), multiple operation, time sharing, reliability, graphics, theseslogic design, multics system, *graphs, trees(mathematics), *computers, *networks, computers, security, data basesThe thesis examines some of the technical aspects of efficiency and reliability which are affected by access control in complex, multiuser data bases. 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)
