Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital physical signature devices are used for computer resource security, then identification capability is provided, but vulnerability to attacks (anonymizing, spoofing, cloning) increases
Solution Approach 1:
The patent replaces digital physical signature devices with analog physical signature devices. The analog device uses physical properties (optical, acoustic, or other analog characteristics) to generate unique signatures that are inherently resistant to digital attacks like cloning and spoofing. This substitution fundamentally changes the security paradigm from digital to physical/analog domain.
Solution Approach 2:
The analog physical signature device employs composite structures combining multiple materials or physical media with different analog properties. This complexity makes the device difficult to replicate while maintaining stable unique identification characteristics, thereby improving security reliability against various attacks.
2Reliability
If digital physical signature devices with additional security measures are implemented, then tamper-resistance is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex digital security systems with simpler analog physical devices. The analog nature of the device provides inherent tamper-resistance through physical properties without requiring additional digital security layers, encryption algorithms, or special-purpose processors, thus reducing overall system complexity.
3Reliability
If digital physical signature devices with encryption/decryption processes are used, then security is improved, but production cost increases
Solution Approach 1:
The patent eliminates the need for encryption/decryption hardware and processes by using analog physical signature devices. These devices generate unique identifiers through physical properties directly, without requiring special-purpose processors or cryptographic operations, significantly reducing production costs while maintaining security.
4Ease of operation
If analog physical signature devices are used, then ease of binding to computer resources is improved, but compatibility requirements increase
Solution Approach 1:
The patent designs analog physical signature devices with universal interfaces and standardized connection methods that can be bound to various types of computer resources (hardware, software, networks). The device incorporates multiple interface types and adaptation mechanisms to ensure broad compatibility across different computing platforms and resource types.
