Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of access authentication processes between LTE and blockchain networks is challenging due to differences in their communication protocols, which hinders seamless switching and cross-network-domain communication.
Innovation Solution
An authentication method and system that involves an identity management entity in the LTE network generating a digital certificate for terminal equipment, which is then verified and used to allocate a blockchain identity by an identity proxy entity, enabling the equipment to access the blockchain network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If separate authentication processes are used for LTE and blockchain networks, then each network can maintain its own security standards, but network switching becomes slow and complex
Solution Approach 1:
The patent merges the authentication processes of LTE and blockchain networks into a unified flow. The identity management entity in the LTE network generates a digital certificate that is directly usable for blockchain network authentication, combining what were previously separate authentication sequences into one integrated process.
Solution Approach 2:
The digital certificate generated by the LTE network's identity management entity serves multiple functions: it authenticates the terminal in the LTE network and simultaneously serves as the authentication credential for accessing the blockchain network, eliminating the need for separate authentication mechanisms.
2Adaptability or versatility
If protocol conversion is implemented between LTE and blockchain networks, then cross-network communication becomes possible, but the system complexity increases
Solution Approach 1:
The patent introduces an identity proxy entity as an intermediary between the LTE network and blockchain network. This intermediary receives the digital certificate from the LTE network, verifies its validity, and translates it into the appropriate format for blockchain network authentication, simplifying the protocol conversion process.
Solution Approach 2:
The authentication system is segmented into distinct functional entities: the identity management entity in the LTE network, the identity proxy entity for translation, and the blockchain network. This segmentation allows each component to handle specific protocol requirements independently while maintaining overall system integration.
3Ease of operation
If a unified identity management system is implemented, then network switching becomes seamless, but traceability and verification requirements increase
Solution Approach 1:
The patent implements a feedback mechanism where the identity proxy entity verifies the digital certificate's validity by checking it against the blockchain network's requirements, and provides confirmation back to the terminal equipment. This feedback loop ensures traceability and verification while maintaining seamless switching.
