Quantum Entangled Key Exchange for Secure Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Point-to-point (P2P) encryption in data transmission is resource-intensive and vulnerable to unauthorized data disclosure, particularly when multiple devices are involved, as each device must decrypt and re-encrypt data, leading to performance overhead and security risks.
Innovation Solution
Implementing a secure key exchange method using quantum entangled random number generators (QERNG) and key derivation functions (KDF) to establish a common key among end devices and intermediary nodes, allowing secure communication without intermediary devices gaining knowledge of the key, thereby eliminating the need for frequent decryption and re-encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If P2P encryption is used for data transmission through multiple devices, then data security is improved, but computational overhead increases and transmission speed decreases
Solution Approach 1:
A common encryption key is established in advance among all devices in the transmission chain before data transmission begins. This preliminary key establishment eliminates the need for repeated decryption and re-encryption operations at each intermediary device, significantly reducing computational overhead and improving transmission speed while maintaining security.
2Reliability
If P2P encryption is used for data transmission through multiple devices, then data security is improved, but computational resources are consumed
Solution Approach 1:
The common key is established beforehand among all devices, including intermediary devices, before the actual data transmission. This preliminary action allows intermediary devices to forward encrypted data without performing computationally intensive decryption and re-encryption operations, thereby reducing energy consumption and computational resource usage while preserving security.
3Productivity
If a common key is shared among end devices and intermediary devices, then communication efficiency is improved, but security against unauthorized access deteriorates
Solution Approach 1:
Different devices are assigned different roles with different security requirements. End devices (first and last devices) are configured to establish a separate private key exchange channel, while intermediary devices are configured with the common key for efficient forwarding. This local differentiation of security properties allows the system to maintain both efficiency and security.
Solution Approach 2:
The encryption key system is segmented into two parts: a common key shared among all devices for efficient data forwarding, and a private key exchange channel between end devices for secure key establishment. This segmentation allows each part to serve its specific purpose optimally without compromising the other.
