Abstract
This work is an analysis of the use of a multilevel
secure computer system to execute tactical combat
applications programs. Using the Gemini Trusted Multiple
Microcomputer Base, currently under evaluation by the
Department of Defense Computer Security Center, applications
and test programs were written and implemented in order to
expose some characteristics of the system.
Using a Janus/Ada compiler with the necessary library
alterations for the Gemini machine, a simple weapons
application program was implemented in a system designed to
simulate a tactical environment where classified material
can be handled in spite of the different levels of security
held by the operators that can access the system.
The loss in performance due to the secure operating
system's overhead is estimated in order to establish the
tradeoffs in performance gains due to parallel processing
capability of the multiprocessor system.
