Abstract:
A secured network system comprising:a first data processor for receiving and processing classified data;a second data processor for receiving and processing said classified data;a first personal computer card reader located in proximity to said first data processor;a second personal computer for receiving and processing said classified data;said first personal computer card reader being adapted to receive a microchip embedded card, said first personal computer card reader providing a first authorization signal whenever said microchip embedded card is presented to and authenticated by said personal computer card reader;said second personal computer card reader being adapted to receive said microchip embedded card, said second personal computer card reader providing a second authorization signal whenever said microchip embedded card is presented to and authenticated by said second personal computer card reader;a first power relay switch connected to said first data processor;a second power relay switch connected to said second data processor;a controller connected to said first power relay switch and said second power relay switch, said controller being connected to said first personal computer card reader to receive said first authorization signal from said personal computer card reader, said controller being connected to said second personal computer card reader to receive said second authorization signal from said personal computer card reader;said controller, responsive to said first authorization signal, activating said first power relay switch, said power relay switch when activated coupling said first data processor to an external power supply to enable said first data processor allowing said first data processor to receive and process said classified data;said controller, responsive to said second authorization signal, activating said second power relay switch, said second power relay switch when activated coupling said second data processor to said external power supply to enable said second data processor allowing said second data processor to receive and process said classified data;said first power relay switch having a normally closed tamper switch coupled to said first data processor and said controller;said controller monitoring the normally closed tamper switch of said first power relay switch to detect when the normally closed tamper switch of said first power relay switch is opened which indicates that an unauthorized user of said secured network system is attempting to bypass said first power relay switch;said second power relay switch having a normally closed tamper switch coupled to said second data processor and said controller;said controller monitoring the normally closed tamper switch of said second power relay switch to detect when the normally closed tamper switch of said second power relay switch is opened which indicates that said unauthorized user of said secured network system is attempting to bypass said second power relay switch;a first data relay switch connected to said first data processor, said first data relay switch being connected to a classified network server which generates said classified data;a first network card reader connected to said controller, said first network card reader being adapted to receive said microchip embedded card, said first network card reader providing a third authorization signal whenever said microchip embedded card is presented to and authenticated by said first network card reader;said controller receiving said third authorization signal from said network card reader, said controller, responsive to said third authorization signal, enabling said first data relay switch to provide for a first data transfer of said classified data from said classified network server through said first data relay switch to said first data processor allowing an authorized user of said secure network system to process said classified data with said first data processor;a second data relay switch connected to said second data processor, said second data relay switch being connected to said classified network server;a second network card reader connected to said controller, said second network card reader being adapted to receive said microchip embedded card, said second network card reader providing a fourth authorization signal whenever said microchip embedded card is presented to and authenticated by said second network card reader;said controller receiving said fourth authorization signal from said second network card reader, said controller, responsive to said fourth authorization signal, enabling said second data relay switch to provide for a second data transfer of said classified data from said classified network server through said second data relay switch to said second data processor allowing said authorized user of said secure network system to process said classified data with said second data processor;said first data relay switch including a normally closed tamper switch connected to said controller;said controller monitoring the normally closed tamper switch of said first data relay switch to detect when the normally closed tamper switch of said first data relay switch is opened which indicates that said unauthorized user of said secured network system is attempting to bypass said first data relay switch;said second data relay switch including a normally closed tamper switch connected to said controller; andsaid controller monitoring the normally closed tamper switch of said second data relay switch to detect when the normally closed tamper switch of said second data relay switch is opened which indicates that said unauthorized user of said secured network system is attempting to bypass said second data relay switch.
