Abstract
A device ID inquiry unit transmits a device ID request containing an IP address as a communication address of a destination, and receives a communication device identifier from a communication device. A device ID determination unit checks whether or not the communication device identifier is the same device identifier as a device ID. If the communication device identifier is the same device identifier as the device ID, a public key acquisition unit acquires a device public key from the communication device, and a device certificate transmission unit transmits a device certificate containing the device public key to the communication device.
