Multilevel secure front end for data communications

Abstract

This thesis demonstrated the feasibility of using a multilevel secure computer system to augment traditional security measures used to safeguard sensitive information in an office to office communication environment. A multilevel secure communication interface can be used for high speed transmission of a wide variety of computerized information, from text files, to large volumes of bulk data including computer program listings. Such a system significantly reduces the delays associated with traditional transmission techniques such as couriers, and registered mail. The ability to encrypt all external communications provides additional security. By automating message processing functions, providing secure storage devices, and restricting access to sensitive information, the multilevel secure communications interface can greatly improve overall system security.
