Gaming Machine Memory Segmentation for Authentication Time Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaming machines with increased storage capacity experience longer authentication times, leading to extended out-of-service periods due to the need for comprehensive data integrity checks.
Innovation Solution
The method segregates memory into critical and non-critical areas, authenticating the critical area before enabling the gaming machine and the non-critical area during operation, using digital signatures based on public key cryptography.

Engineering Contradiction Analysis
1Quantity of substance
If total storage capacity is increased, then storage capability is improved, but authentication time increases
Solution Approach 1:
The memory is divided into a first subset (critical area) and a second subset (non-critical area). The critical area contains operational data components necessary for machine operation, while the non-critical area contains additional storage capacity. This segmentation allows the system to authenticate only the critical area before operation, reducing authentication time while maintaining storage capability.
2Reliability
If comprehensive data integrity checking is performed, then security is improved, but machine out-of-service period increases
Solution Approach 1:
The authentication process is segmented into two phases: pre-operation authentication of the critical area (first subset) and post-operation or concurrent authentication of the non-critical area (second subset). This allows the machine to enter service after verifying critical components, maintaining security while reducing out-of-service time.
Solution Approach 2:
The critical area authentication is performed as a preliminary action before machine operation begins. This ensures that essential operational data is verified in advance, allowing the machine to start service without waiting for complete authentication of all storage areas.

AI summary
A computer-implemented method of authenticating a memory of a gaming machine uses a computing device having a processor communicatively coupled to a memory. The method includes identifying a first subset of the memory including one or more operational data components associated with operating the gaming machine. The method also includes identifying a second subset of the memory. At least some of the second subset of the memory is distinct from the first subset of the memory. The method further includes authenticating the first subset of the memory while the gaming machine is in a disabled state. The method also includes enabling operation of the gaming machine after the authenticating the first subset of the memory if the authentication of the first subset of the memory is successful. The method further includes authenticating the second subset of the memory while the gaming machine is in an enabled state.
