Abstract:
A transmitting/receiving system for authenticating between transmission and receiving devices by using a code, wherein a code for authenticating is shared between a plurality of transmission devices or a plurality of receiving devices. Each of the plurality of transmission devices is provided with a variable-code storage unit, a control-signal transmission unit, a variable-code update unit, and a variable-code synchronization transmission unit. The variable-code storage unit stores a variable code. The control-signal transmission unit transmits a control signal including the variable code. The variable-code update unit updates the variable code after transmission of the control signal. The variable-code synchronization transmission unit transmits the updated variable code to another transmission device among the plurality of transmission devices, and sets the updated variable code as the new variable code.
