Abstract:
1. A data processor configured to perform data communication with an external device via wireless communication with a relay transmitter, the data processor comprising: a communication unit configured to perform wireless communication with the relay transmitter; a storage unit configured to store a first physical address for the relay transmitter; an authentication starter configured to, in response to the data processor being turned on, wirelessly transmit, to the relay transmitter, an instruction to start authentication between the data processor and the relay transmitter along with a physical address for the data processor; an address receiver configured to receive a second physical address for the relay transmitter wirelessly transmitted from the relay transmitter as a response to the instruction; a determining unit configured to make a determination as to whether the second physical address for the relay transmitter which is received from the relay transmitter wirelessly is identical to the first physical address for the relay transmitter which had been stored in the storage unit before the data processor is turned on; and a connecting unit configured to, when one or more authentication requirements are satisfied, establish wireless connection between the communication unit and the relay transmitter so as to achieve the data communication between the data processor and the external device via the relay transmitter, the authentication requirements including the determination by the determining unit that the second physical address for the relay transmitter is identical to the first physical address for the relay transmitter.
