Abstract
The wireless communication system 1000 includes an access point 100, a wireless terminal 200A, and a wireless terminal 200B. The access point 100 and the wireless terminal 200A each uniquely generate a shared key using an identical conversion function on the basis of unique information read from an RFID tag 310A of an RFID card 300A, and then generate a common encryption key on the basis of the shared key. The access point 100 and the wireless terminal 200B each uniquely generate a shared key using an identical conversion function on the basis of unique information read from an RFID tag 310B of an RFID card 300B, and then generate a common encryption key on the basis of the shared key.
Claims6
A wireless communication device comprising:
- an acquisition portion which acquires prescribed information read from an RFID (Radio Frequency Identification) tag that retains unique information;
- a shared key generation portion which uniquely generates based on the prescribed information a shared key serving as a basis to generate an encryption key for use in encrypted communication with another wireless communication device;
- a shared key storage portion which stores the shared key;
- an authentication process portion which carries out authentication between the wireless communication device and the another wireless communication device, using the shared key as authentication information;
- an encryption key generation portion which generates the encryption key based on at least the shared key, in the event that authentication by the authentication process portion is successful;
- and
- a communication portion which carries out encrypted communication using the encryption key.
A wireless communication system for carrying out encrypted communication between a first wireless communication device and a second wireless communication device, wherein
- the first and second wireless communication devices respectively include:
- an acquisition portion which acquires prescribed information read from an RFID (Radio Frequency Identification) tag that retains unique information;
- a shared key generation portion which uniquely generates based on the prescribed information a shared key serving as a basis to generate an encryption key for use in the encrypted communication;
- a shared key storage portion which stores the shared key;
- an authentication process portion which carries out authentication between present wireless communication device and another wireless communication device, using the shared key as authentication information;
- an encryption key generation portion which generates the encryption key based on at least the shared key, in the event that authentication by the authentication process portion is successful;
- and
- a communication portion which carries out encrypted communication using the encryption key.
A network device comprising:
- an acquisition portion which acquires prescribed information read from an RFID (Radio Frequency Identification) tag that retains unique information;
- an authentication information generation portion which generates based on the prescribed information authentication information for use in authentication of the network device and another network device;
- an authentication information storage portion which stores the authentication information;
- and
- an authentication process portion which carries out the authentication using the authentication information.
