Computer security violations have become a serious threat to both corporate and national defense activities. By extending the work done by Myers et. el. in the development of the capability based addressing system for the SWARD at IBM, a Computer architectural approach has been developed which solves all known software based internal computer security problems. The problems solved include (but are not restricted to):(1) Violations of priority and access priveleges by highly skilled users,(2) The clasic "Trojan Horse" problem,(3) Access and alteration of sensitive data-bases by unauthorized users(4) The "Lost Key" problem of advanced capability based addressing systems.This solution proposes and develops an architectural approach which manages a sophisticated capability based addressing system entirely in hardware. As a result, the architectures developed by this approach tend to be somewhat hardware intensive in that they require unusual amounts of control and memory not available to any user (it is maintained soley for security purposes).
