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.
