PHYSICAL SECURITY ACCESS CONTROL SYSTEM TO LOCAL AREA NETWORK (LAN) AND WIDE AREA NETWORK (WAN)

摘要

A secured network system (10) comprises a readykey controller (12) connected to a first card reader (14) and a power relay switch (16). A user inserts a microstrip embedded card into the first card reader (14) which transmits a first electrical authorization signal to the readykey controller (12) indicating that the user is authorized to use a computer for receiving and processing classified data. The readykey controller (12) then supplies a first signal to a power relay switch (16) activating the power relay switch (16) which couples the computer's power supply to an external power source. The secured network system (10) also allows the user to receive and process classified data, by setting a manual A/B switch (28) to a predetermined position which allows a secured network server (30) to be connected to the computer (18). The user inserts his proximity card into a second card reader which then transmits a second electrical authorization signal to the readykey controller (12). The readykey controller (12) next sends a second signal enable signal to a data relay switch (26). The second enable signal enables the data relay switch (26) connecting the secured network switch to the computer (18) for the transmission of data between the network server (30) and the computer (18).
