Routing Device Filtering Connected Object Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Local area communication networks are vulnerable during the pairing of connected objects, particularly when using wireless technologies like Wi-Fi or IEEE 802.15.4, as existing pairing procedures lack security measures, potentially exposing sensitive data to malicious entities and compromising user privacy.
Innovation Solution
Implementing a method where a routing device within the local area network detects connected objects, assigns a confidence score based on various criteria, and notifies a trusted device to either allow or block access, enhancing security and privacy by filtering access based on the object's vulnerability and eco-design scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new connected object is paired with the local area communication network using existing pairing procedures, then the connected object can access the network and provide new services, but the network becomes vulnerable to malicious individuals or systems due to lack of security measures
Solution Approach 1:
The routing device performs preliminary actions by detecting the connected object before pairing, assigning a confidence score based on device information, and notifying trusted devices in advance. This preliminary security assessment prevents malicious objects from compromising the network during the pairing process.
Solution Approach 2:
The routing device acts as an intermediary between the connected object and the local area communication network. It mediates the pairing process by detecting objects, evaluating their confidence scores, and controlling access based on trusted device notifications, thereby protecting the network from unauthorized or malicious connections.
2Reliability
If pairing procedures include security measures to verify object authenticity, then network security is improved, but the pairing process becomes more complex and time-consuming
Solution Approach 1:
The routing device autonomously performs security assessments by detecting connected objects, retrieving their information, assigning confidence scores, and notifying trusted devices without requiring complex user intervention. This self-service approach maintains security while simplifying the user experience.
Solution Approach 2:
The system introduces a confidence score parameter to evaluate connected objects objectively. This quantitative parameter automates the security assessment process, replacing complex manual verification procedures with a streamlined automated evaluation based on device information and trusted device notifications.
3Reliability
If the routing device assigns confidence scores and notifies trusted devices for each pairing request, then access security is enhanced by blocking malicious devices, but the pairing process requires additional communication steps
Solution Approach 1:
The routing device implements a feedback mechanism by notifying trusted devices of pairing requests and receiving their responses. This feedback loop enables security decisions based on trusted device input, enhancing access control while maintaining an efficient automated process that does not significantly extend pairing time.

AI summary
A method for filtering access of a connected object to a local area communication network, implemented by a routing device of the local area network. The method includes: detecting a connected object waiting for pairing within the local network; assigning a confidence score to the connected object, based on information relating to the connected object; notifying a trusted device of the local area network of the request to pair the connected object and of the assigned confidence score; and upon receipt of a pairing refusal from the trusted device, blocking an access of the connected object to the local area network.
