Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional digital signature certification chains are used, then digital data can be validated, but security certainty is insufficient and cannot ensure high confidence in the signatory's authority
Solution Approach 1:
The patent combines multiple digital signatures into a single aggregated digital signature that represents the collective authentication of multiple authorities. This merging approach enhances security certainty by requiring consensus from multiple trusted parties while maintaining authentication accuracy through the mathematical properties of aggregate signature schemes.
Solution Approach 2:
The patent introduces a trusted third party (TTP) that issues credentials and verifies aggregated signatures. This intermediary enhances security certainty by providing a centralized authority that can validate the authenticity of aggregate signatures, while maintaining system decentralization for actual operations.
2Adaptability or versatility
If multiple security protocols are implemented for different industries and communication methods, then security coverage is improved, but implementation complexity and cost increase significantly
Solution Approach 1:
The patent creates a universal authentication framework based on aggregate signatures that can be applied across different industries and communication protocols. The core cryptographic primitives remain the same regardless of application context, allowing a single implementation to serve multiple security needs without requiring separate protocol stacks for each use case.
Solution Approach 2:
The patent allows the same aggregate signature framework to be adapted to different security requirements by changing parameters such as the number of authorities involved, the type of credentials used, and the verification threshold. This enables flexible deployment from low-security to high-security scenarios without fundamental changes to the system architecture.
3Reliability
If comprehensive authentication mechanisms are deployed to ensure high security, then validation reliability is improved, but implementation cost increases
Solution Approach 1:
The patent uses cryptographic copying where a single aggregated signature can represent multiple individual signatures simultaneously. This allows the system to achieve the security of multiple separate authentication mechanisms while incurring the computational and storage costs of only a single compact signature structure, significantly reducing implementation costs compared to verifying each signature separately.
4Measurement precision
If detailed verification of signatory authority is performed, then authentication accuracy is improved, but processing time increases
Solution Approach 1:
The patent performs preliminary authentication by having authorities sign individual components before aggregation. The aggregate signature structure pre-encodes the verification logic, allowing receiving parties to verify the collective authority of multiple signers in a single operation rather than performing sequential verification of each signature and their associated credentials.
