Abstract

The communication unit transmits and receives a communication message. The authentication processor performs an authentication process for establishing the network connection by transmitting and receiving an authentication message to and from an authentication server through the communication unit. The encryption information generator generates an encryption key shared with the authentication server when the authentication process is successfully completed. The first message generator generates a first communication message instructing the destination device to acquire the encryption key from the authentication server. The second message generator generates a second communication message including data to be transmitted to the destination device. The communication unit transmits the first communication message to the destination device, encrypts the second communication message with the encryption key, and transmits an encrypted second communication message to the destination device.
