Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If classical encryption methods are used to protect communication in time-sensitive networks, then security is provided, but timing discrepancies caused by malicious messages cannot be detected or corrected
Solution Approach 1:
The patent introduces a quantum channel as an intermediary mechanism to transmit quantum bits (qubits) for synchronization timing. This quantum intermediary enables detection of timing discrepancies and malicious interference that classical encryption alone cannot detect, while maintaining the time-sensitive network's operational integrity
Solution Approach 2:
The patent changes the fundamental parameter of information transmission from classical bits to quantum bits, utilizing quantum mechanical properties (such as superposition and entanglement) to enable both secure communication and precise timing synchronization. This parameter change allows simultaneous achievement of security and timing accuracy
2Reliability
If quantum channel is used for secret information exchange, then security against malicious actors is improved, but system complexity increases
Solution Approach 1:
The patent segments the communication system into distinct quantum and classical channels, each handling specific functions. The quantum channel handles secret information exchange and synchronization, while the classical channel handles routine communication, reducing overall system complexity through functional separation
Solution Approach 2:
The quantum channel serves multiple functions simultaneously: it provides secure secret information exchange, enables precise timing synchronization, and offers detection of malicious interference. This multi-functionality reduces the need for separate systems, thereby managing complexity
3Loss of time
If synchronization time is determined via classical channel, then timing is provided, but timing errors cannot be detected when malicious messages are present
Solution Approach 1:
The patent implements a feedback mechanism where quantum bits transmitted through the quantum channel provide real-time information about timing synchronization status. This feedback enables detection of timing errors caused by malicious messages, allowing the system to identify and correct synchronization issues
