Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cryptographic systems are vulnerable to quantum computing, hardware flaws, and side-channel attacks, leading to insecurity in data transmission and storage, especially with the use of small encryption keys which can be easily compromised, exposing large amounts of data to unauthorized access.
Innovation Solution
The implementation of a system using quantum key distribution (QKD) for secure network communication, where source data is encrypted with a dynamically generated random key equal to or greater than the data size, and transmitted and verified using QKD to ensure secure transmission and storage, with the ability to detect eavesdropping and retransmit if necessary, and utilizing blockchain data for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If small encryption keys (e.g., 256 bits) are used for data encryption, then the encryption process is efficient and fast, but the security is compromised as keys can be easily discovered and transmitted to recover encrypted data
Solution Approach 1:
The patent divides the encryption key into multiple separate key components stored on different storage devices. Instead of using a single large key, the system uses multiple smaller key fragments that must be combined through secret sharing to reconstruct the full encryption key. This segmentation prevents attackers from obtaining the complete key by compromising individual storage devices.
Solution Approach 2:
The patent transitions from traditional single-key encryption to a multi-dimensional key distribution system where key components are distributed across multiple storage devices and locations. This adds a spatial and organizational dimension to key management, requiring physical and cryptographic coordination to access encrypted data.
2Reliability
If the One Time Pad (OTP) encryption technique is used, then mathematical security is proven, but technological difficulties in key storage and distribution make widespread use impractical
Solution Approach 1:
The patent implements segmented key distribution where the OTP key is divided into multiple fragments stored on separate storage devices. This maintains the mathematical security of OTP while reducing the complexity of key distribution by breaking down the key management task into manageable pieces that can be distributed physically.
Solution Approach 2:
The patent introduces storage devices as intermediaries between the key generation system and the encryption process. These storage devices securely hold key fragments and enable their retrieval only when needed for decryption, simplifying the overall system architecture while maintaining OTP security.
3Productivity
If physical storage devices are used for data transport, then large amounts of data can be transferred quickly, but the storage devices may be stolen or corrupted during transport or storage
Solution Approach 1:
The patent segments data and encryption keys across multiple physical storage devices. No single device contains both the data and the complete decryption key, preventing theft or corruption of individual devices from compromising the entire data set. This distributes the risk across multiple physical components.
4Productivity
If standard encryption techniques are used with modern processors, then data can be encrypted and transmitted, but hardware flaws and side-channel attacks can leak cryptographic key information
Solution Approach 1:
The patent segments the encryption key into multiple independent components stored on separate devices. Even if hardware flaws or side-channel attacks expose key information on one device, the complete key cannot be reconstructed without access to all storage devices, thereby maintaining security despite vulnerabilities in individual components.

Function Achieved in This Case
This approach provides cryptographically unbreakable and secure data transmission and storage, immune to quantum cryptanalysis and side-channel attacks, ensuring that even if one storage device is compromised, the data remains secure as it requires multiple devices for decryption, thus minimizing exposure risks.

AI summary
Systems and methods for secure network communications of data using quantum key distribution (QKD) are presented. Source data is provided. The source data is encrypted to produce encrypted data and key data corresponding to the encrypted data. Using QKD, the key data is transmitted from a first network location to a second network location. Successful transmission of the key data to the second location is verified, and upon verification, the encrypted data is transmitted from the first network location to the second network location using QKD. Successful transmission of the encrypted data to the second location is verified, and upon verification, the encrypted data is decrypted with the key data to provide a data output.
