Expiration Detection in Trusted Execution Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid obsolescence of computing platforms leads to management, operational, and security issues due to outdated software and firmware, causing vulnerabilities and requiring either updates or replacement.
Innovation Solution
A computing platform management method and apparatus that includes an expiration date detection system, utilizing a trusted execution environment with a tamper-proof storage and firmware module to regulate operations based on whether the current date is earlier than the platform's expiration date, allowing for secure updates and notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If computing platforms are used for extended periods without updates, then operational costs are reduced and device longevity is increased, but security vulnerabilities accumulate and platforms become susceptible to malware attacks
Solution Approach 1:
The patent implements expiration date detection and platform status monitoring before security vulnerabilities can be exploited. By proactively identifying outdated platforms through expiration date certificates and notifying users in advance, the system enables preventive updates or replacements, thereby extending safe device longevity while preventing security breaches.
2Object-affected harmful factors
If computing platforms are updated frequently to maintain security, then security vulnerabilities are reduced and platforms remain protected, but operational disruptions increase and management complexity grows
Solution Approach 1:
The patent implements an automated platform management system that self-monitors expiration dates, self-identifies outdated platforms, and self-notifies users of upcoming expirations. This automated self-service approach reduces manual management complexity while maintaining security by ensuring platforms are updated before vulnerabilities arise.
3Object-affected harmful factors
If outdated computing platforms are discarded and replaced, then security vulnerabilities are eliminated and platforms remain secure, but resource waste increases and environmental impact grows
Solution Approach 1:
The patent enables extended platform utilization by proactively monitoring expiration dates and notifying users in advance, allowing platforms to be used safely until their actual expiration rather than being prematurely discarded. This extends the productive life of computing platforms, reducing electronic waste and resource consumption while maintaining security through timely updates.
4Reliability
If platform expiration status is monitored and enforced, then security is improved and outdated platforms are identified, but system complexity increases and additional management overhead is required
Solution Approach 1:
The patent introduces an intermediary firmware module that mediates between the processor and the expiration date certificate storage. This intermediary component simplifies the overall system by centralizing expiration date management functions, providing a clean interface for security checks while maintaining reliability through automated monitoring and notification mechanisms.
