Abstract:
PURPOSE:To make it impossible to analyze the system of constituent signals by processing a code signal with a hidden cryptographic function and sending the processed signal. CONSTITUTION:A transmission signal from a transmitter is received by a reception section 11, a received code signal is processed by a cryptographic function set to an arithmetic section 13 and the resulting processing signal is outputted. A signal comparison section 14 compares whether or not the calculated processing signal is coincident with the received processing signal. When the compared signal is coincident, a lock signal is generated from a lock signal generating means 15, stored in a storage section 16 and a succeeding area is released by an area setting means 17.
