Compressed Encryption With Reusable Parameters for Quantum Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current encryption methods are not resilient to quantum computer-based attacks and lack maturity, leading to inefficiencies in data transmission and organizational hierarchies, especially when dealing with large numbers of encrypted messages.
Innovation Solution
Reusing encryption parameters to send one copy per message, combined with sanitizable or redactable signature schemes, to reduce data transmission and enable more efficient organizational hierarchies, using lattice-based or isogeny-based encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption parameters are sent with each encrypted message to ensure security, then message security is maintained, but data transmission size increases significantly
Solution Approach 1:
The system performs preliminary generation of encryption parameters (public keys, system parameters) before actual message transmission. These parameters are generated in advance and stored in the system, allowing them to be reused for multiple messages without regenerating and retransmitting them each time, thus reducing transmission size while maintaining security
Solution Approach 2:
The encryption parameters, particularly the system parameters and public keys, are designed to be universal and reusable across multiple encryption operations. A single set of parameters can encrypt multiple messages, allowing the same cryptographic material to serve multiple functions and multiple recipients without degradation of security
2Reliability
If new post-quantum encryption schemes are adopted to ensure quantum resilience, then security against quantum attacks is improved, but the maturity and depth of study of the methods decrease
Solution Approach 1:
The patent combines multiple post-quantum cryptographic approaches (lattice-based encryption, isogeny-based encryption, code-based encryption) into a unified hybrid encryption system. This merging allows the system to leverage the security strengths of different mathematical problems while maintaining a consistent operational framework, effectively combining emerging quantum-resistant technologies into a cohesive solution
Solution Approach 2:
The encryption system uses composite cryptographic constructions that combine multiple cryptographic primitives and mathematical hard problems. Similar to composite materials in engineering, the system composite multiple cryptographic approaches (lattice, isogeny, code-based) to create a more robust and versatile encryption scheme that benefits from the diverse security properties of each component
3Ease of operation
If encryption parameters are not reused and a new copy is sent with each message, then each message can be independently decrypted, but efficiency gains are lost and data transmission increases
Solution Approach 1:
The system creates a single master copy of the encryption parameters (system parameters and public keys) that can be replicated and distributed to multiple recipients. Instead of creating unique parameter sets for each message, the system copies the same parameter set across multiple encryption operations, significantly reducing the amount of data that needs to be transmitted while maintaining the ability for each recipient to independently decrypt their designated messages
