Reader Application Card Segmentation for Secure Data Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reader devices face challenges in upgrading security levels without hardware changes, as upgrades require secure environment certification, leading to either under- or over-equipping for security needs.
Innovation Solution
A communication system where a reader application card, capable of operating as a data switch, allows selection between internal and external reader applications, enabling easy field upgrades without hardware changes, and controlling data transmission between user cards and background systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the reader is equipped with the highest possible security level hardware, then security level is improved, but device cost increases
Solution Approach 1:
The invention segments the reader system into two parts: a base reader unit with standard hardware and a separate reader application card that contains the security application. This allows the security functionality to be upgraded independently without replacing the entire reader hardware, thus reducing costs while maintaining high security levels through software-based solutions.
Solution Approach 2:
The reader application is extracted from the reader hardware and placed on a separate card. This extraction allows the security application to be developed, tested, and certified independently, then deployed to various readers without requiring hardware changes or re-certification of the entire system.
2Reliability
If the reader is upgraded to a higher security level, then security level is improved, but device complexity increases
Solution Approach 1:
The base reader unit is designed to be universal and can work with multiple different reader application cards. This multi-functionality allows the same hardware to support various security levels and applications by simply changing the application card, avoiding the need for multiple specialized hardware versions and reducing overall system complexity.
3Reliability
If the reader is customized and certified for higher security, then security level is improved, but ease of operation worsens due to secure environment requirements
Solution Approach 1:
The reader application is developed, tested, and certified in advance in a secure environment before deployment. Once certified, the application can be freely distributed and installed on readers in the field without requiring secure environment operations during deployment, thus maintaining high security while enabling easy field upgrades.
