Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current encryption methods face challenges in securely transmitting data over large communications networks, particularly due to processing overhead, non-detectable tampering, and difficulties in implementing quantum key distribution across multiple nodes, which can be expensive and require significant resources.
Innovation Solution
The method involves generating and transmitting a random data stream with indicators to identify valid data, using quantum teleportation to transfer encrypted data across nodes in a communications network, allowing secure data transmission without revealing the encryption key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If classical encryption methods are used to secure data transmission, then data confidentiality is maintained, but processing overhead increases and key management becomes complex across multiple nodes
Solution Approach 1:
The patent extracts the encryption key from the data transmission process entirely. Instead of encrypting data with keys that must be managed across nodes, the system uses quantum random number generation to create one-time pad keys that are generated and used locally, eliminating key distribution and management complexity while maintaining security.
Solution Approach 2:
The patent introduces quantum random number generation as an intermediary mechanism that provides secure key material without requiring direct key exchange between nodes. The quantum-generated random numbers serve as a mediator that enables secure communication without the complexity of traditional key management protocols.
2Reliability
If quantum key distribution is implemented across multiple nodes, then unconditional security is achieved, but resource requirements and implementation costs increase significantly
Solution Approach 1:
The patent segments the quantum security implementation into individual node operations. Each node independently generates quantum random numbers for its own key material without requiring quantum communication infrastructure between nodes. This segmentation allows quantum-level security to be achieved at each node independently, eliminating the need for expensive quantum key distribution networks across multiple nodes.
Solution Approach 2:
The patent employs one-time pad keys generated by quantum random number generators at each node. These keys are used once and then discarded, eliminating the need for key reuse or complex key management. The disposable nature of these keys provides unconditional security while keeping the implementation simple and resource-efficient at each node.
3Productivity
If encryption keys are reused multiple times, then processing efficiency is maintained, but security vulnerability increases if keys are compromised
Solution Approach 1:
The patent implements continuous quantum random number generation at each node, providing a continuous stream of fresh key material. This continuous generation ensures that new keys are always available for each communication session without interruption to processing efficiency, while the one-time use of each key maintains maximum security.

Data Source
AI summary
Methods and systems for transmitting data are described. A random data stream is generated. A data stream is generated comprising the random data stream and indicators as to which data of the random data stream is valid data to be communicated to a recipient. The random data stream and/or the data stream may be communicated using quantum entanglement.
