A verifiable protection system

Abstract: This paper reports on the design and implementation of the UCLA Virtual Machine System, a multiuser operating system base that has been developed to provide ultra high reliability protection and security. Details are presented of the UCLA-VM system, a prototype of which now exists. Concepts which have influenced its structure are discussed, including program verification, security kernels, virtual machines, virtual memory, and the need for flexible information sharing facilities. A new mechanism, capability faulting, is developed in order to remove much of the virtual memory support from the security kernel. Flexible, reliable control of sharing is obtained by extensions to several of these concepts, especially through the use of levels of kernels.
