Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network access systems face challenges in ensuring network security and authentication for mobile devices that frequently change networks, particularly when accessing unfamiliar or unknown networks.
Innovation Solution
A blockchain-based method for network access points that uses a digitally signed record to transfer the association of a mobile device from a home access point to an away access point, verified by miner components and recorded in a distributed transactional database, ensuring secure and verifiable network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized authentication mechanism is used, then network security is improved, but network connectivity accessibility deteriorates
Solution Approach 1:
The patent segments the centralized authentication system into distributed blockchain nodes, where each access point maintains its own authentication capability through the blockchain ledger. This eliminates the single-point dependency while maintaining security through cryptographic verification of authentication records.
Solution Approach 2:
The blockchain acts as an intermediary layer between devices and access points, providing a decentralized authentication mechanism. The blockchain ledger mediates the verification process by storing and validating authentication records without requiring direct access to a central authentication server.
2Adaptability or versatility
If mobile devices frequently change networks, then adaptability is improved, but network security deteriorates
Solution Approach 1:
The system performs preliminary authentication by creating and storing authentication records in the blockchain before the device actually accesses the network. This pre-validation ensures that even as devices frequently switch networks, each connection is pre-authorized and cryptographically verified, maintaining security alongside adaptability.
3Reliability
If cryptocurrency transfer is required for network access, then access control security is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements self-service authentication where devices automatically handle cryptocurrency transactions and blockchain verification without user intervention. The device autonomously pays the access fee and verifies its authentication status through the blockchain, eliminating the need for manual security procedures while maintaining strong access control.
