Secure multiprotocol interface

摘要: A network interface for secure multiprotocol data communication includes a doorbell circuit, processor, memory, and bridge circuit. The circuit responds to physical I/O addresses of the host that are mapped by memory management unit registration process. An application program seeking use channel must register virtual address where is or will be stored page addresses. Access functions via therefore denied when requesting process identifier does not successfully compare with performed registrations. password may in association map used communication. abandon requested implied function passwords do compare. Methods an include one more steps (a) establishing controller secured; (b) registering (c) describing blocks reference handle; (d) accomplishing described block established controls secured other channels secured. Security provided against both erroneous operations intentionally effected rouge processes.
