Abstract:
1. A self-authentication communication device comprising: a device ID key generation part that generates, based on a device ID (IDentity) that identifies the self-authentication communication device, encryption key data as a device ID key by using a CPU (Central Processing Unit); a device ID authentication information generation part that generates, based on public key data of the self-authentication communication device and the device ID key generated by the device ID key generation part, authentication information of the public key data as device ID authentication information by using the CPU; a self-authentication information generation part that generates, based on predetermined data and private key data of the self-authentication communication device, authentication information of the predetermined data as self-authentication information by using the CPU; and a self certificate transmission part that transmits a digital certificate, including the predetermined data, the device ID authentication information generated by the device ID authentication information generation part, and the self-authentication information generated by the self-authentication information generation part, to a specific device as a self certificate by using a communication unit.
