Engineering Contradiction Analysis
1Reliability
If quantum-safe digital signatures are integrated into existing software applications, then security against quantum attacks is improved, but device complexity increases
Solution Approach 1:
The patent introduces a quantum-safe digital signature service as an intermediary component that existing software applications can access via REST API. This service handles the complex quantum-safe signature generation and verification operations externally, allowing applications to benefit from quantum security without incorporating the complexity of quantum cryptographic libraries directly into their codebases. The service acts as a mediator between the application and the quantum-safe cryptography infrastructure.
Solution Approach 2:
The patent segments the quantum-safe digital signature functionality into a separate, dedicated service that operates independently from existing software applications. By dividing the system into the application layer (which makes simple API calls) and the signature service layer (which handles complex cryptographic operations), the patent reduces the complexity burden on individual applications while maintaining overall system security.
2Reliability
If quantum-safe digital signature services are implemented, then electronic document security is improved, but ease of operation decreases
Solution Approach 1:
The patent designs the quantum-safe digital signature service to provide universal functionality through standardized REST API interfaces that can be accessed by various types of software applications. The service handles multiple operations (signature generation, verification, status updates) through a unified interface, making it easy for different applications to integrate quantum-safe capabilities without requiring application-specific implementation details. This universal approach simplifies operation while maintaining high security standards.
Data Source
AI summary
Mechanisms are disclosed for decoupled integration of quantum-safe digital signatures into software applications. Electronic document content is stored, by a software application, in connection with a document store. An application programming interface (API) request is issued to a quantum-safe digital signature service. The API request comprises an identifier associated with the electronic document content and a request to generate a quantum-safe signature associated with the electronic document content. The request to generate a quantum-safe signature of the electronic document content causes the quantum-safe digital signature service to perform several steps. First, the electronic document content is retrieved from the document store. Next, a quantum-safe digital signature data structure is generated. Next, the quantum-safe digital signature data structure is stored to the document store. A signing status update is transmitted to the software application. The software application reads the signature data structure from the document store.
