Valuable Medium Processing With Secure-Boot Execution Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valuable medium processing systems lack robust security measures to ensure the integrity and authenticity of software operations, particularly during booting and software updates, which can lead to unauthorized execution of processes and potential misuse of valuable media.
Innovation Solution
A valuable medium processing apparatus equipped with a secure boot function and a processor that executes execution prohibition and release processes, along with a verification apparatus for authentication and vulnerability checks, ensuring secure operation through tamper-resistant security chips and digital certificate-based authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If execution prohibition is implemented to prevent unauthorized processes, then security is improved, but system operational flexibility deteriorates
Solution Approach 1:
The system dynamically adjusts the execution prohibition state based on authentication results. The processor transitions between prohibiting and allowing execution of the second medium process depending on whether the execution apparatus is verified as legitimate, making the security measure adaptive rather than static
Solution Approach 2:
The system changes the execution state parameter from prohibited to allowed based on authentication outcomes. This parameter change enables the system to maintain security during unauthenticated states while permitting normal operations after verification
2Reliability
If authentication processes are performed before allowing execution, then security is improved, but processing time increases
Solution Approach 1:
The authentication process is performed preliminarily before the execution apparatus attempts to execute the second medium process. By verifying legitimacy in advance, the system prevents unauthorized operations without requiring time-consuming verification during actual execution
3Reliability
If security management is implemented using security chips, then software integrity is improved, but device complexity increases
Solution Approach 1:
A security chip serves as an intermediary component between the processor and the software execution environment. This dedicated security module handles authentication and verification functions, isolating complex security management from the main processor and other system components
