ABSTRACT:
One and the other communication terminals for performing wireless communication are connected by a cable. The one communication terminal performs control so that an encryption key is transmitted from the one communication terminal to the other communication terminal by wireless during a period in which the potential of the cable is active. The other communication terminal stores the encryption key received from the one communication terminal within the period in which the potential of the cable is active, as a valid key, for use in subsequent encryption processing.
