APPARATUS AND METHOD FOR CONTROLLING ACCESS TO AND INTERCONNECTION OF COMPUTER SYSTEM RESOURCES

摘要

A compact, physically secure, high-performance access controller (16, 18) is electrically connected to each access-managed resource (12, 14) or group of resources (10) in a computer system. Whenever access managed resources attempt to establish communications, their associated access controllers exchange sets of internally generally access authorization codes utilizing protocols characterized by multiple random numbers, resource authorization keys, serial number verification, and session authorization keys. Each session employs different exception keys derived from multiple random numbers and multiple hidden algorithms. Tables of authorized requesting and responding resources are maintained in a protected memory in each access controller. An authorization table building procedure is augmented by an optional central access control system (56) that employs a parallel control network (62, 64, 66) to centrally manage the access control tables in an access-controlled system of resources.
