Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cryptographic protocols are updated periodically to maintain security against quantum computers, then security reliability is improved, but the complexity of coordinating updates across all participants increases
Solution Approach 1:
The patent segments the cryptographic protocol into discrete, modular components (cryptographic modules, protocol files, software components) that can be updated independently. This allows participants to update only the necessary segments rather than coordinating complete protocol replacements across the entire system, reducing coordination complexity while maintaining security reliability.
Solution Approach 2:
The patent implements dynamic update mechanisms where cryptographic protocols can be modified in real-time or near-real-time based on security threats. The system allows flexible scheduling of updates without requiring simultaneous coordination across all participants, enabling adaptive security maintenance without complex synchronization protocols.
2Reliability
If all participants update their cryptographic software simultaneously to maintain protocol compatibility, then communication reliability is improved, but the time required for updates increases
Solution Approach 1:
The patent allows participants to prepare and test cryptographic software updates locally before deploying them to production systems. Protocol files and cryptographic modules can be pre-validated against compatibility requirements, enabling participants to update at their own pace without waiting for simultaneous coordination, thus reducing total update time while maintaining communication reliability.
Solution Approach 2:
The patent uses protocol files that contain references to cryptographic modules rather than embedding the actual cryptographic code. This allows participants to download and install updated cryptographic modules independently, with the protocol files serving as templates that ensure compatibility. Multiple participants can follow the same protocol file template without needing to coordinate each update action, reducing time loss while maintaining reliability.
3Strength
If cryptographic software modules are added to enhance security against quantum algorithms, then security strength is improved, but the complexity of modifying existing protocols increases
Solution Approach 1:
The patent separates existing cryptographic functionality from new quantum-resistant cryptographic modules, allowing them to coexist within the same protocol framework. New modules can be added as independent units that interface with existing protocols through standardized connectors, enhancing security strength without requiring complex modifications to existing protocol logic.
Solution Approach 2:
The patent designs protocol files and cryptographic frameworks to be multi-functional, capable of supporting both traditional cryptographic algorithms and new quantum-resistant algorithms. This universal design allows the same protocol infrastructure to accommodate multiple cryptographic modules without requiring separate modification paths, simplifying the process of adding security enhancements while maintaining compatibility with existing systems.
Data Source
AI summary
Embodiments are directed to methods and systems for crypto-agile encryption and decryption. A computer system can possess a protocol file that identifies one or more cryptographic software modules. Using these cryptographic software modules, the computer system can generate a plurality of shared secrets and a session key, then use the session key to encrypt a message. The message can be sent to a server computer that can subsequently decrypt the message. At a later time, the protocol file can be updated to identify a different set of cryptographic software modules, which can be used to encrypt messages. Further, the server computer can transmit additional cryptographic software modules to the computer system, enabling the computer system to use those cryptographic software modules to generate cryptographic keys. As such, the cryptographic protocol file can be changed in response to changes in the cryptographic needs of the computer system.
