Integration of factoring by high-assurance function to the application of the application

摘要

PROBLEM TO BE SOLVED: To execute, in parallel with each other, a large-scale system having advanced features and a small-scale system for providing high-level security.;SOLUTION: An application's functionality is partitioned into two groups depending on whether or not a specific operation like processing of secret data is executed. Separate software objects (processors) are created to perform these two groups of operations. A trusted processor handles secure data and runs in a high-assurance environment. When another processor detects secure data, that data are sent to the trusted processor. The data are wrapped in such a way that allows it to be routed to the trusted processor, and prevents the data from being deciphered by any entity other than the trusted processor. An infrastructure is provided that wraps objects, routes the objects to the correct processor, and allows their integrity to be attested through a chain of trust leading back to a base component that is known to be trustworthy.;COPYRIGHT: (C)2005,JPO&NCIPI
