Abstract
Abstract A secured network system comprising a readykey controller connected to a st card reader and a power relay switch. The user inserts a microchip embedded card into the first card reader which transmits a first electrical authorization signal to the readykey controller indicating that the user is authorized to use a computer for receiving and processing classified data. The readykey controller then supplies a first enable signal to a power relay switch activating the power relay switch which couples the computer's power supply to an external power source. The secured network system also allows the user to receive and process classified data, by setting a manual A/B switch to a predetermined position which allows a secured network server to be connected to the computer. The user next inserts his proximity card into a second card reader which then transmits a second electrical authorization signal to the readykey controller indicating that the user is authorized to receive and process classified data. The readykey controller next sends a second enable signal to a data relay switch. The second enable signal enables the data relay switch connecting the secured network switch to the computer which allows for the transmission of classified data between the secured network server and the computer.
