Wireless communication device, mac address management system, wireless communication method, and program

A Media Access Control (MAC) address management system for providing a temporary MAC address that is used by a wireless communication device for performing wireless communication through an access point comprising:

• a distributing server device that is provided in a network, manages the temporary MAC address, a unique MAC address, a public encryption key pre-stored in the wireless communication device and a secret encryption key corresponding to the unique MAC address in relation to each other, encodes the temporary MAC address corresponding to the unique MAC address of the wireless communication device by the secret encryption key corresponding to the unique MAC address, and transmits the encoded code data of the temporary MAC address to the wireless communication device;
• and
• the wireless communication device that acquires the temporary MAC address from the distributing server device, wherein the wireless communication device comprises:
• a code data acquiring section that acquires from the distributing server device the code data of the temporary MAC address by transmitting the unique MAC address given to the wireless communication device, and stores the code data of the temporary MAC address in a Random Access Memory (RAM) of the wireless communication device;
• and
• a wireless communication section that decodes the code data of the temporary MAC address by using a the public encryption key pre-stored in a Read Only Memory (ROM) of the wireless communication device only when performing the wireless communication using the temporary MAC address.

A wireless communication method of a Media Access Control (MAC) address management system in which a wireless communication device acquires a temporary MAC address, that is used for performing wireless communication through an access point, from a distributing server device provided in a network storing the temporary MAC address corresponding to a unique MAC address of the wireless communication device, the method comprising:

• requesting, from the wireless communication device to the distributing server device, to send the temporary MAC address by transmitting the unique MAC address of the wireless communication device;
• obtaining, in the distributing server device, the temporary MAC address corresponding to the unique MAC address received from the wireless communication device, coding the temporary MAC address by a secret encryption key corresponding to the unique MAC address, and transmitting code data of the temporary MAC address to the wireless communication device;
• storing, in the wireless communication device, the code data of the temporary MAC address in a Random Access Memory (RAM) of the wireless communication device;
• and
• decoding, in the wireless communication device, the code data of the temporary MAC address by using a public encryption key pre-stored in a Read Only Memory (ROM) of the wireless communication device only when performing the wireless communication using the temporary MAC address,
• wherein the temporary MAC address, the unique MAC address, the public encryption kev and the secret encryption key are managed in relation to each other in the distributing server device.

A computer-readable non-transitory recording medium having embodied thereon a computer program, which when executed by a computer, causes the computer to function as a wireless communication device that obtains a temporary Media Access Control (MAC) address, that is used for performing wireless communication through an access point, from a distributing server device provided in a network storing the temporary MAC address corresponding to a unique MAC address and transmitting code data of the temporary MAC address encoded by a secret encryption key corresponding to the unique MAC address to the wireless communication device, the wireless communication device comprising:

• a code data acquiring section that acquires the code data of the temporary MAC address from the distributing server device by transmitting the unique MAC address given to the wireless communication device, and stores the code data of the temporary MAC address in a Random Access Memory (RAM) of the wireless communication device, and
• a wireless communication section that decodes the code data of the temporary MAC address by using a public encryption key pre-stored in a Read Only Memory (ROM) of the wireless communication device only when performing the wireless communication using the temporary MAC address,
• wherein the temporary MAC address, the unique MAC address, the public encryption key and the secret encryption key are managed in relation to each other in the distributing server device.
