Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional data encryption technologies are used, then communication security is provided, but the system becomes susceptible to code breaking by schemes with sufficient computing resources
Solution Approach 1:
The patent transitions from conventional encryption parameters to quantum key distribution parameters, utilizing quantum mechanical properties (superposition, entanglement) to generate and distribute keys. This parameter change fundamentally alters the security basis from computational complexity to physical laws, making code breaking infeasible even with sufficient computing resources.
Solution Approach 2:
The patent replaces conventional cryptographic mechanisms (mathematical algorithms like RSA, AES) with quantum mechanical mechanisms. The quantum key distribution system uses quantum states to encode information and quantum entanglement to ensure security, substituting the mechanical/computational encryption system with a quantum-based system that is theoretically unhackable.
2Adaptability or versatility
If conventional quantum key-based communication technologies are used, then quantum-based communications are enabled, but the technologies are not directed towards securing wireless service-based communications and remain under development
Solution Approach 1:
The patent creates a universal quantum key distribution system that can secure multiple types of wireless communications simultaneously. The system provides quantum security for diverse applications including IoT devices, smart cities, defense communications, and V2X technologies, making the quantum key infrastructure universally applicable across different wireless service scenarios.
Solution Approach 2:
The patent introduces a smart hub as an intermediary component that bridges quantum key distribution and wireless network infrastructure. The smart hub manages quantum key generation, distribution, and integration with existing wireless networks, serving as a mediator that enables quantum security without requiring complete replacement of the wireless communication infrastructure.
3Reliability
If quantum key distribution is implemented for secure communications, then code breaking resistance is achieved, but the system complexity increases due to authentication, validation, and monitoring requirements
Solution Approach 1:
The patent segments the quantum key distribution system into distinct functional modules: authentication component, validation component, quantum key generation component, communication component, and monitoring component. This segmentation allows each module to perform its specific function independently, making the overall complex system more manageable and easier to implement while maintaining security.
Solution Approach 2:
The patent implements preliminary authentication and validation actions before quantum key distribution begins. The system authenticates communication entities and validates their authorization in advance, ensuring that only authorized entities can participate in quantum key distribution. This preliminary action simplifies subsequent operations by pre-establishing trust relationships.

AI summary
Smart hub quantum key distribution (QKD) and security management in advanced networks (e.g., 5G and beyond) is presented herein. A smart hub for QKD system provisions, via a network slice of a control plane of a communication network, a group of communication entities within the communication network to facilitate, via a QKD service, a quantum key-based communication session between a pair of communication entities of the group of communication entities; and in response to receiving, from a communication entity of the pair of communication entities via the network slice, a first request to establish the quantum key-based communication session, sending, to a QKD system via a user plane of the communication network, a second request to establish, via the QKD service, the quantum key-based communication session using a quantum-based communication channel.
