Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminal devices perform data transmission through relay terminal devices, then extended coverage and connectivity are achieved, but the complexity of establishing secure connections increases due to extensive signaling interactions with core network devices
Solution Approach 1:
The access network device serves as an intermediary between terminal devices and core network devices for key distribution. Instead of terminal devices directly interacting with core network devices through extensive signaling, the access network device receives key generation parameters from the core network and distributes them to terminal devices, simplifying the connection establishment process while maintaining security.
Solution Approach 2:
The patent extracts the key distribution function from the core network device and relocates it to the access network device. This separation allows the core network to focus on key generation while the access network handles key distribution to terminal devices, reducing signaling complexity without compromising security.
2Reliability
If terminal devices interact extensively with core network devices to obtain keys, then secure connection establishment is achieved, but processing efficiency deteriorates due to low key generation speed
Solution Approach 1:
The access network device performs preliminary actions by receiving key generation parameters from the core network device in advance and storing them locally. When terminal devices need keys for secure communication, the access network device can quickly distribute these pre-obtained parameters without requiring terminal devices to engage in extensive real-time signaling with the core network, thus improving processing efficiency while maintaining security.
3Reliability
If extensive signaling interactions are performed with core network devices for key acquisition, then secure connections are established, but processing efficiency is reduced due to increased signaling overhead
Solution Approach 1:
The access network device acts as a mediator that caches key generation parameters from the core network device. This intermediary role eliminates the need for terminal devices to repeatedly communicate with the core network device for each key acquisition, significantly reducing signaling overhead and time loss while maintaining the security guarantees provided by core network-based key generation.
