CONTROLLED ACCESS SYSTEM AND METHOD

摘要

The system includes a cryptographic key (17) that transmits a signal to a wireless transceiver (26). The wireless transceiver (26) is connected to a microprocessor (18), a keyboard (23), a drive (22), a monitor (24), a rom (21), and a ram (19). The cryptographic key (17) transmits a wireless cryptographic signal is sent between the cryptographic key (17) and the host (16) to request authorization to use the host (16). The signal is decrypted and processed after being received to determine if access is to be granted.
