More Information
Summary:Inherent terminal identification information and a terminal unique key are stored in an on-board terminal, and server-side terminal identification information and a server-side terminal unique key, which are same information as the above terminal identification information and terminal unique key are stored in a server. And, the on-board terminal transmits the terminal identification information to the server via a communication terminal, and the server performs terminal authentication according to the server-side terminal identification information, and if the authentication is success, transmits encrypted software for the on-board terminal of which authentication was success to the communication terminal. The communication terminal transmits the encrypted software to the on-board terminal, and the on-board terminal obtains a software unique key, which is encrypted by the server-side terminal unique key by the server, via the communication terminal, decrypts the encrypted software using the software unique key, and installs it.
