Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital signature certification is used, then digital data can be authenticated, but security certainty is insufficient and vulnerability to cyber-attacks remains high
Solution Approach 1:
The system segments the authentication process into multiple independent verification layers: device identity verification through aggregated digital signatures, operator accreditation verification, and authorization data validation. Each layer operates independently to provide comprehensive security without relying on a single point of failure.
Solution Approach 2:
The patent introduces an intermediary accreditation mechanism where a trusted authority issues accreditation data that mediates between the device's digital signature and the operator's identity. This intermediary layer enhances security certainty by adding an additional verification step that is resistant to cyber-attacks.
2Reliability
If multiple verification protocols are implemented to ensure high security, then authentication reliability improves, but implementation complexity and cost increase significantly
Solution Approach 1:
The system employs universal cryptographic primitives (one-way accumulators, digital signatures, hash functions) that can be implemented across diverse devices and communication protocols. The aggregated digital signature mechanism serves multiple verification purposes simultaneously, reducing overall system complexity while maintaining high authentication reliability.
Solution Approach 2:
The patent changes the verification parameters from complex multi-factor authentication to streamlined cryptographic verification. By using aggregated digital signatures that can be verified through simple cryptographic operations, the system maintains high reliability while significantly reducing implementation complexity and computational overhead.
3Measurement precision
If comprehensive authentication data is collected to ensure high certainty validation, then security is improved, but data processing time and computational resources increase
Solution Approach 1:
The system performs preliminary actions by pre-computing and storing aggregated digital signatures and accreditation data in structured formats. This allows the verification process to operate on pre-prepared data structures, reducing real-time computational requirements and verification time while maintaining high validation certainty.
Solution Approach 2:
The patent replaces complex mechanical verification processes with efficient cryptographic operations. The use of one-way accumulator functions and digital signature verification substitutes for time-consuming manual or mechanical authentication methods, achieving high validation certainty with minimal processing time.
