All terminal information is displayed on a terminal identity generating tool interface, a user selects a terminal needing authorization, then clicks an authorization function button, and the generated unique identification number and the secret key are sent to each networked terminal together for permanent storage. The identification number can be an electronic identification card number allocated to the terminal and used for corresponding identity authentication of the terminal.
