Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tokenization systems are vulnerable to key compromise and brute force attacks, especially with the advent of quantum computing, which can exponentially increase the efficiency of certain calculations, compromising cryptographic-based tokenization methods.
Innovation Solution
The Post-Quantum Unique Key Per Token (PQUKPT) system generates a unique, instance-specific key for each tokenization instance, providing protection against key compromise and brute force attacks by using a unique key derivation mechanism or random key generation for each token, ensuring that if a key is compromised, only that specific token is affected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single key is used for tokenization, then the system is simple and efficient, but the system becomes vulnerable to key compromise and brute force attacks
Solution Approach 1:
The patent divides the single key into multiple unique keys, with each key associated with a specific token or data element. This segmentation ensures that compromise of one key does not affect others, resolving the contradiction between system simplicity and security reliability.
Solution Approach 2:
Each key is assigned specific local properties and scope, where keys are unique to specific tokens or data elements. This local quality approach provides targeted security where needed while maintaining overall system efficiency.
2Productivity
If quantum computing is used to enhance computational power, then processing efficiency improves, but cryptographic security is compromised
Solution Approach 1:
The patent changes the cryptographic parameters by using unique keys for each token instead of a single shared key. This parameter change makes the system resistant to quantum computing attacks while maintaining computational efficiency for legitimate operations.
3Reliability
If unique keys are generated for each token, then security against key compromise is improved, but system complexity increases
Solution Approach 1:
The system automatically generates and manages unique keys for each token without requiring manual intervention. This self-service approach handles the complexity of key generation and distribution while maintaining high security standards.
Solution Approach 2:
The patent implements feedback mechanisms where the system tracks and manages key usage, allowing for automatic key rotation and renewal. This feedback loop simplifies key management complexity while maintaining continuous security protection.
