Ephemeral Key Management via Index-Based Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryptographic systems, such as AES-256, are vulnerable to attacks through social engineering and key theft, as they rely on shared and stored keys, which can be compromised without breaking the cryptosystem itself, leading to significant data breaches.
Innovation Solution
A cryptographic management key system that generates and manages ephemeral, disposable keys using dynamic random or pseudo-random information, eliminating key storage and exchange, and introducing a temporal element for frequent key changes, ensuring that keys are never stored and are only used momentarily, making them difficult for attackers to exploit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If shared secret keys are stored and exchanged in traditional cryptographic systems, then encryption can be performed, but the system becomes vulnerable to key theft through social engineering or insider breaches
Solution Approach 1:
The patent extracts the actual key material from the system by using indices to access a remote key database. Instead of storing and exchanging keys directly, the system exchanges only the indices (e.g., 32-bit integers) that reference keys stored in a centralized or distributed database. This extraction eliminates the vulnerability of storing sensitive key material while maintaining the ability to perform encryption operations.
Solution Approach 2:
The patent introduces a key management server as an intermediary between communicating devices. This server holds the master key database and provides keys to devices upon request using index-based access. The intermediary centralizes key management and eliminates the need for devices to store or exchange sensitive key material, reducing the attack surface for key theft.
2Ease of operation
If keys are stored in databases or memory, then key management is simplified, but the stored keys become targets for attackers and can be compromised
Solution Approach 1:
The patent extracts sensitive key material from storage locations by using a database indexing system. Keys are stored in a centralized database but accessed through indices rather than being cached in device memory or stored in accessible storage. This extraction ensures keys are never held in vulnerable storage locations while maintaining ease of access through the indexing mechanism.
Solution Approach 2:
The patent implements dynamic key retrieval where keys are fetched from the database only when needed based on the index, rather than being statically stored. This dynamic approach ensures keys are not persistently stored in vulnerable locations and can be rapidly rotated or revoked by updating the index mappings in the database.
3Productivity
If traditional key exchange methods are used, then communication can be established, but stolen credentials can be used in subsequent attacks and may remain undetected
Solution Approach 1:
The patent implements dynamic key retrieval where keys are fetched from the database only when needed based on the index, rather than being statically stored. This dynamic approach ensures keys are not persistently stored in vulnerable locations and can be rapidly rotated or revoked by updating the index mappings in the database.
Solution Approach 2:
The system incorporates feedback mechanisms through the key management server that can detect and respond to suspicious activities. The server monitors key requests and can identify patterns indicating compromised credentials or unauthorized access, enabling real-time response to security threats and improving detection capability.
