Architecture for utilizing coprocessing systems to increase performance in security adapted computer systems

摘要

A security system adapted for use with a base computer 29 includes a security computer 31 for reading and writing data from memory in the base computer system 29, for transferring data to and from an encryption system 3, for transferring encrypted data to and from a storage system 14, and for interfacing with a trusted path interface device 22. The security system includes a system for regulating, and for interrupting or delaying, operation of the base computer in response to signals from means for associating, with each data group within the security system, data specifying an individual user.
