Abstract
A gaming machine to conduct a wagering game comprises a processing apparatus and a secondary apparatus. To inhibit unauthorized persons from replacing some or all of the software executed by the processing apparatus with unapproved software, the processing apparatus transmits a security message to the secondary apparatus. The secondary apparatus, in turn, validates the security message and transmits an enable signal when the validation is successful, or a disable signal when the validation is not successful. The processing apparatus is allowed to access to game data based on receipt of the enable signal and is denied access to game data based on receipt of the disable signal.
