Abstract
A gaming device security system is disclosed which includes two processing areas linked together and communicating critical gaming functions via a security protocol wherein each transmitted gaming function includes a specific encrypted signature to be decoded and validated before being processed by either processing area. The two processing areas include a first processing area having a dynamic RAM and an open architecture design which is expandable without interfering or accessing critical gaming functions and a second "secure" processing area having a non-alterable memory for the storage of critical gaming functions therein.
