Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cryptographic systems face challenges in providing secure, efficient, and scalable encryption solutions that maintain high entropy and resist brute-force attacks, especially in dynamic and distributed battlespace environments, where data needs to be accessible across various platforms while ensuring robust key management and access control.
Innovation Solution
A deterministic cryptographic system using polynomial or quadratic coefficients and multi-variable geometric surfaces generates ephemeral symmetric keys, eliminating the need for key storage and enabling secure, per-data-object encryption and decryption, with access policies integrated to manage key distribution and ensure only authorized entities can access the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional cryptographic key management systems are used to enable secure data access across multiple platforms, then data accessibility is improved, but key storage requirements increase and key compromise risk increases
Solution Approach 1:
The patent extracts the cryptographic key from the system entirely, eliminating key storage requirements. Instead of storing keys in key management systems, the invention uses deterministic key generation where keys are computed on-demand from publicly available data and secret parameters, removing the need for traditional key storage infrastructure
Solution Approach 2:
The system performs self-service by generating cryptographic keys deterministically from available data without external key management. Each platform can independently regenerate the same key using the deterministic function and shared parameters, eliminating dependence on centralized key storage and distribution systems
2Reliability
If cryptographic keys are stored securely in key management systems, then key security is maintained, but system complexity and key management overhead increase
Solution Approach 1:
The patent removes the key management subsystem entirely by extracting the key from storage and replacing it with deterministic generation. This eliminates the complexity of key provisioning, storage, rotation, and revocation while maintaining security through mathematical properties of the deterministic function
Solution Approach 2:
The system uses ephemeral session keys generated deterministically for each data access operation. These keys exist only temporarily in memory during the encryption/decryption process and are never stored, replacing permanent key storage with transient computational objects that are discarded after use
3Device complexity
If deterministic key generation is used to eliminate key storage, then key management complexity is reduced, but ensuring key entropy and resistance to brute-force attacks becomes more challenging
Solution Approach 1:
The patent segments the cryptographic key into two components: a deterministic component derived from publicly available data and a secret component from a secure parameter. This segmentation allows the key to be generated deterministically while maintaining high entropy through the secret parameter that prevents brute-force attacks
Solution Approach 2:
The system changes the parameters of key generation from random number generation to deterministic computation using cryptographic hash functions. By transforming the input data through multiple hashing iterations and combining it with secret parameters, the system maintains key entropy while enabling deterministic regeneration
Data Source
AI summary
A deterministic encryption key generating method along with a cryptographic system is disclosed as a component in a battlespace management system or platform within the battlespace. The systems method uses the intersection of an equation representing a polynomial or two-variable quadratic (PQ-Equation) with a secure and secret 3-dimensional mathematical geometric shape, or manifold, to generate an ephemeral symmetric encryption key. Digital objects, files, and data can be cryptographically secured using this process with a unique per-file or per-data object key, which is destroyed after each use. The process combines coefficients of a PQ-Equation mapped onto the manifold to create or recreate the key. PQ-Equation coefficients are stored within the protected file, accessible via the client and transmitted to the computational server possessing the secret manifold. The client device possesses no knowledge of the manifold and the computational server receives no knowledge of the digital object contents, ensuring the confidentiality and integrity of the information being protected allowing the digital object to be securely stored or transmitted over a network or Internet with per protected data object defined access policies to the decryption key.
