Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryptographic systems, such as RSA and Diffie-Hellman, are vulnerable to quantum computers, which can potentially break modern public-key encryption using algorithms like Shor's and Grover's, necessitating a migration to quantum-resistant algorithms, but this migration is complex due to the sheer volume of data and complexity of systems, especially in financial and governmental sectors.
Innovation Solution
The implementation of post-quantum cryptography (PQC) systems that use techniques like PQC communications channel-based cryptography, hash-based cryptography, lattice-based cryptography, and zero-knowledge proof cryptography to secure data transmission, authentication, and key exchange, ensuring resistance to quantum computer attacks.

1Power
If quantum computers are developed, then computational power and problem-solving capability are improved, but security protocols and cryptographic systems become vulnerable
Solution Approach 1:
The patent applies preliminary action by implementing post-quantum cryptographic algorithms before quantum computers become widely available. The system proactively migrates from classical cryptographic protocols (RSA, ECC) to quantum-resistant algorithms, preparing security infrastructure in advance to prevent future vulnerabilities when quantum computing capabilities mature.
Solution Approach 2:
The patent applies parameter changes by transitioning cryptographic systems from classical mathematical problems (integer factorization, discrete logarithms) to quantum-resistant mathematical problems (lattice-based, code-based, multivariate polynomial equations). This fundamental change in cryptographic parameters ensures security remains effective against both classical and quantum computational threats.
2Reliability
If migration to quantum-resistant algorithms is implemented, then long-term security is improved, but system complexity and migration difficulty increase
Solution Approach 1:
The patent applies segmentation by dividing the migration process into distinct phases and components: key generation, key exchange, encryption, decryption, and authentication. Each cryptographic operation is implemented as a separate module using standardized post-quantum algorithms, allowing incremental deployment and testing without requiring complete system replacement at once.
Solution Approach 2:
The patent applies universality by implementing a unified post-quantum cryptographic framework that can handle multiple security functions (authentication, encryption, key exchange) using the same quantum-resistant mathematical foundations. This multi-functional approach reduces overall system complexity compared to maintaining separate classical and quantum-resistant systems.
3Ease of operation
If classical cryptographic systems are used, then ease of operation and compatibility are maintained, but vulnerability to quantum attacks increases
Solution Approach 1:
The patent applies the intermediary principle by introducing post-quantum cryptographic protocols as a mediating layer between existing applications and the underlying cryptographic infrastructure. This allows classical systems to maintain their ease of operation while the intermediary PQC layer provides quantum-resistant security, enabling gradual migration without disrupting operational simplicity.
