Game Controller Offline Chip Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing game controllers cannot authenticate game chips securely when the network is down, leading to either reduced security or interrupted gameplay.
Innovation Solution
A game controller with a chip communication unit, communication connection unit, and storage unit that downloads authentication data from a server and stores it offline, allowing for chip authentication and data accumulation during network outages, ensuring continuous gameplay without security compromise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If game chip authentication is performed by connecting to a server via network, then authentication security is improved, but game continuity deteriorates when network is down
Solution Approach 1:
The system downloads and stores authentication data from the server in advance during online periods. When the network is down, the game controller uses this pre-stored offline data to authenticate game chips, ensuring both security and continuity without real-time server connection.
2Productivity
If offline authentication data is stored in the game controller, then game continuity is improved during network outages, but data security deteriorates
Solution Approach 1:
The system creates a copy of the authentication data stored on the server and stores it locally in the game controller's storage unit. This copy enables offline authentication while the master copy remains securely on the server, balancing accessibility and security.
3Reliability
If real-time server connection is maintained for authentication, then data integrity is improved, but system complexity increases
Solution Approach 1:
The system dynamically switches between online and offline authentication modes based on network availability. When the server is accessible, it performs real-time authentication; when unavailable, it transitions to using pre-stored offline data, providing adaptive operation without requiring complex permanent dual-mode infrastructure.
Data Source
AI summary
A game controller downloads a chip database at a predetermined timing from a server and stores the chip database as offline data in a storage unit, determines whether communication with the server is possible, when a chip communication unit accesses a game chip, and authenticates the game chip with reference to a offline data table when the communication is impossible.
