Zusammenfassung:This specification defines the technical requirements for a Security Protection Module (SPM). An SPM is the hardware portion of a security kernel whose function is to mediate through a descriptor structure, all interactions between elements of a protected minicomputer. The SPM evaluates the propriety of all requests, and performs address translation between virtual requests and physical resources. The SPM contains a fast-access cache for storing copies of descriptors in an effort to minimize the performance overhead associated with security. See also Rept. no. ESD-TR-76-351.
