Gaming Machine Memory Authentication Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As gaming machines increase in complexity and storage capacity, the integrity checking of their data storage becomes longer, leading to extended authentication times and potential downtime, which can keep machines out of service for longer periods.
Innovation Solution
The method involves segmenting the memory into critical and non-critical regions, authenticating the critical region before enabling the machine, and then authenticating the non-critical region while the machine is operational, allowing for faster startup and reduced downtime.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the total storage capacity of the gaming machine is increased, then the storage capability is improved, but the authentication time is extended
Solution Approach 1:
The patent divides the storage media into two distinct subsets: a first subset containing critical operational data components that must be authenticated before the machine can operate, and a second subset containing non-critical data that can be authenticated after operation begins. This segmentation allows the machine to authenticate only the essential portion of storage data during startup, significantly reducing authentication time while still ensuring security for critical functions.
2Reliability
If integrity checking of all stored data is performed, then security is improved, but the machine downtime is extended
Solution Approach 1:
The patent performs preliminary authentication of the first subset of storage media containing critical operational data before the gaming machine is allowed to operate. This preliminary action ensures that essential security requirements are met during startup, while the authentication of the second subset of non-critical data is deferred to a later time when the machine is already operational, thus minimizing downtime while maintaining security.
3Reliability
If the authentication process is made more thorough, then security is improved, but the processing time is extended
Solution Approach 1:
The patent applies partial action by authenticating only the first subset of storage media containing critical operational data components during the startup process, rather than performing a complete authentication of all storage media. This partial authentication approach provides sufficient security for machine operation while significantly reducing processing time. The authentication of the remaining second subset is performed later when it does not impact startup speed.

AI summary
A computer-implemented method of authenticating a memory of a gaming machine is provided. The method uses a computing device having a processor communicatively coupled to a memory. The method includes identifying a first area of the memory including one or more operational data components associated with operating the gaming machine. The first area further includes a public key associated with an original memory area. The method also includes authenticating, by the processor, the first area using at least the public key from the first area.
