Innovation Solution
Introducing a wireless authorization storage device that stores reader data, allowing modifications to be made without altering the reader hardware, enabling compatibility with existing systems and facilitating configuration, security enhancements, and integration of new devices or applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reader hardware is designed to prevent access or replacement of hardware components storing secrets, then security is improved, but adaptability deteriorates
Solution Approach 1:
The system separates the secret storage function from the reader hardware by introducing a distinct secret storage device. The reader contains only the interface and logic for interaction, while secrets are stored in a separate secured module or external device. This segmentation allows the reader hardware to remain unchanged while enabling flexibility in secret management through software updates or replacement of the secret storage component alone.
Solution Approach 2:
An intermediary secret storage device is introduced between the reader and the secret data. This intermediary component acts as a buffer that protects the reader hardware from direct access to secrets while enabling flexible secret management. The intermediary can be a secured module, smart card, or external device that stores secrets and provides them to the reader as needed, thus decoupling the hardware from the secrets.
2Reliability
If hardware replacement is required to modify reader secrets, then security is improved, but device complexity deteriorates
Solution Approach 1:
By segmenting the system into a reader component and a separate secret storage component, the patent eliminates the need to replace entire hardware assemblies. Only the secret storage module needs to be updated or replaced, significantly reducing device complexity while maintaining security.
Solution Approach 2:
The system enables copying or transferring of secrets between different secret storage devices without requiring hardware replacement. Secrets can be replicated, backed up, or migrated between storage devices through software processes, reducing the complexity associated with hardware replacement procedures.
3Reliability
If hardware replacement is required to update reader secrets, then reliability is improved, but loss of time deteriorates
Solution Approach 1:
Segmenting the secret storage into a separate replaceable module allows for rapid updates without replacing the entire reader hardware. The secret storage module can be quickly swapped or updated in place, significantly reducing the time required for maintenance and updates while preserving system reliability.
Solution Approach 2:
The system allows secrets to be prepared and validated in advance before being loaded into the secret storage device. This preliminary preparation reduces the time required during actual deployment or updates, as the secret data is ready for immediate transfer without requiring complex hardware replacement procedures.

AI summary
An authorization system (10) includes a reader (1) for a reader-card interaction (92) with a card (2), and a logic module configured to assign the reader (1) and the card (2) to each other and to make operable the reader-card interaction (92) based on authorization data comprising reader data and card data. The logic module is further configured to read via a non-contact interface (12.1) device data from an authorization storage device (5) and to assign the reader (1) to the card (2) based on the device data for making operable the reader-card interaction (92). The authorization storage device (5) is arranged spaced apart from the non-contact interface (12.1) at an essentially fixed distance (9), for example during the reader-device interaction (95). Using the device data makes it possible to enable efficiently the reader-card interaction (92) in case the reader data does not match the card data, for example.
