NFC Authorization for IoT Network Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices often lack security mechanisms, making them vulnerable to malicious attacks, and existing security measures like proprietary interfaces and certificates can be compromised, posing risks to users and infrastructure.
Innovation Solution
Implementing a method where IoT network nodes can only communicate if they receive authorization after a completed NFC connection with a defined mobile communication terminal, using a two-factor or three-factor verification process that includes spatial proximity and encrypted data transfer through a cloud server, ensuring secure access and data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary interfaces and certificates are used to secure IoT devices, then security is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a mobile communication terminal as an intermediary device that mediates between the user and the IoT device. This terminal handles the complex authentication process by establishing an NFC connection with the IoT device, verifying certificates, and managing the authorization workflow, thereby shielding the user from technical complexity while maintaining strong security through certificate-based authentication
2Reliability
If certificates are used for secure data transfer, then security is improved, but vulnerability to hacker attacks increases
Solution Approach 1:
The patent implements preliminary authorization actions where the mobile communication terminal establishes an NFC connection with the IoT device before any data transfer occurs. The terminal verifies the IoT device's certificate in advance, obtains authorization from the server, and only then enables communication. This preliminary security check prevents unauthorized access and hacker attacks by ensuring authentication happens before vulnerability exposure
Solution Approach 2:
The system implements a feedback mechanism where the server provides authorization decisions based on certificate verification results. The mobile terminal receives authorization status feedback and adjusts communication permissions accordingly. This closed-loop feedback system continuously monitors and responds to security conditions, dynamically preventing hacker attacks by revoking or granting access based on real-time authorization status
3Reliability
If NFC connection with mobile terminal is required for authorization, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces complex manual security configuration mechanisms with NFC-based automatic authentication. Instead of requiring users to manually configure certificates, keys, or security parameters, the system uses NFC's proximity-based communication to automatically establish secure connections and trigger authentication workflows, making strong security as easy as bringing devices close together
