A Secure Computer Network.

Abstract

In this thesis, the initial design for a secure computer network is developed. The requirement for a secure computer network is based on the need to protect sensitive and personal information currently processed by computer networks. The concepts of physical security, reference monitors, encryption, and network protocols are presented. Then, the top-level design of the secure computer network is developed. This design consists of secure data bases controlled by Kernelized secure operating systems which are connected by a secure communications subnetwork. The phases of secure communications: location, identification, request, and request response are discussed. A model for the secure communications subnetwork is then presented. This model relies on two major components: Secure Network Interface Computers (SNICs) and a Network Directory and Security Center (NDSC). A finite state analysis of the communication channels demonstrates the security of the model. Recommendations are presented to continue the development of this secure network. (Author)
