Abstract: Disclosed is a hardware based secure multi-level security computing system system. The system comprises a chassis enclosing multiple separate, secure computer devices or domains, each within an electromagnetic shielding Faraday cage. The chassis structure includes internal electromagnetic shields and other features to prevent cross domain electromagnetic interference or compromising emanations. The chassis may be the size of a standard computer tower. The computer devices or domains may be configured for handling information of different classification levels. Optionally, each of the computer devices may operate on significantly less power than a standard computer. Preferably, each computer operates on no more than 50 Watts of power, more preferably on less than 35 Watts of power.

Abstract: A secure all-in-one LCD or LED-based monitor and computer system includes a chassis enclosing the monitor and multiple computers. Two or more physically and electronically isolated computers are installed within the chassis, each having an independent operating system. The system also includes a power supply, a hardware-based electro-mechanical key/lock preferably with a non-duplicable key for user access. The chassis is constructed of conductive material to mitigate the effects and vulnerabilities between internal computers and outside sources, other computers, or listening devices. The internal computers are separated and isolated by internal walls made of conductive materials to militate against vulnerabilities introduced by multiple computers being hosed inside the same chassis. Rugged components and methods are used in order to withstand extreme shock and vibration as well as low and high operating temperatures.
