1Reliability
If classical cryptographic algorithms (RSA, DH) are used, then current security protocols are maintained and systems operate efficiently, but the system becomes vulnerable to quantum computer attacks that can break these algorithms
Solution Approach 1:
The patent changes the cryptographic algorithm parameters from classical algorithms (RSA, DH) to post-quantum algorithms (lattice-based, code-based, multivariate polynomial, hash-based). This parameter change transforms the mathematical foundation of cryptography to be resistant to quantum attacks while maintaining the fundamental encryption/decryption functionality.
Solution Approach 2:
The patent performs preliminary migration to post-quantum cryptography before quantum computers become a practical threat. By proactively implementing PQC algorithms now, the system prepares for future quantum attacks, ensuring security continuity when quantum computing capabilities are realized.
2Reliability
If post-quantum cryptographic algorithms are implemented, then quantum resistance is achieved, but the computational complexity and processing requirements increase
Solution Approach 1:
The patent segments the cryptographic processing into distinct modular components: key generation modules, encryption modules, decryption modules, and signature modules. Each module handles specific PQC operations independently, making the complex PQC implementation more manageable and allowing parallel processing where applicable.
Solution Approach 2:
The patent designs a universal PQC framework that can handle multiple cryptographic operations (encryption, decryption, signing, verification) using a common set of mathematical primitives and data structures. This multi-functionality reduces overall system complexity by avoiding separate implementations for each cryptographic function.
3Reliability
If post-quantum cryptographic algorithms are implemented, then quantum resistance is achieved, but the processing time and computational resources increase
Solution Approach 1:
The patent implements hybrid cryptographic schemes that combine classical and post-quantum algorithms. The system performs partial encryption using both classical (faster) and PQC (quantum-resistant) algorithms, providing quantum resistance while maintaining acceptable performance through the faster classical component.
Solution Approach 2:
The patent applies different cryptographic algorithms to different parts of the data or different security requirements. High-security data receives full PQC treatment, while less sensitive data may use hybrid or classical algorithms, optimizing the balance between security and performance based on local requirements.
