A method to transmit commands across a gaming network is implemented with digitally signed messages. The command messages are generated upon a triggering event, such as the winning of a bonus. The messages are digitally signed by the transmitting node and transmitted to the subservient device. When the subservient device receives the message, it verifies the signature and executes the command. If the signature does not verify, the subservient device may raise an alarm.
