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 by solving integer factorization and discrete logarithm problems quickly, posing a threat to data security even before quantum computing capabilities are fully realized.
Innovation Solution
The implementation of post-quantum cryptography (PQC) systems that use techniques like hash-based, lattice-based, isogeny-based, code-based, and zero-knowledge proof cryptography to generate and apply encryption attributes based on data attributes, risk profiles, and cryptographic performance information, ensuring data security against quantum attacks.

Engineering Contradiction Analysis
1Speed
If quantum computers are used to break current cryptographic systems, then computational speed is improved, but data security is compromised
Solution Approach 1:
The patent converts the harmful effect of quantum computing (ability to break current cryptography) into a benefit by developing post-quantum cryptographic algorithms that leverage quantum-resistant mathematical problems. These new algorithms use lattice-based, code-based, or hash-based cryptography that remains secure against quantum attacks, thus transforming the quantum threat into an opportunity for enhanced security.
Solution Approach 2:
The patent changes the fundamental parameters of cryptographic algorithms by transitioning from RSA/Diffie-Hellman (based on integer factorization and discrete logarithms) to post-quantum algorithms (based on lattice problems, code problems, or hash functions). This parameter change in the mathematical foundation makes the system resistant to quantum computational power while maintaining cryptographic functionality.
2Reliability
If post-quantum cryptographic techniques are implemented, then data security is improved, but computational overhead increases
Solution Approach 1:
The patent applies local quality by implementing hybrid cryptographic systems that combine classical and post-quantum algorithms selectively. Different cryptographic operations use different algorithms based on their specific requirements, allowing the system to optimize between security and performance on a local rather than global level.
Solution Approach 2:
The patent implements partial action by transitioning to post-quantum cryptography selectively for the most sensitive data and operations, rather than immediately migrating entire systems. This allows organizations to achieve quantum resistance for critical functions while managing computational overhead gradually.
