Pairing Request Phase Duration Control for IoT Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The pairing request phase of connected devices is vulnerable to fraudulent access due to its limited-time or permanent nature, which can lead to unauthorized control of devices like cameras, increasing the risk of malicious activity.
Innovation Solution
A method that detects pairing requests from devices and automatically stops the pairing phase after a customizable duration, using a home gateway to create a quarantine subnetwork, ensuring secure pairing by isolating devices and preventing unauthorized connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pairing request phase is made permanent or repeatedly active, then ease of operation is improved, but security deteriorates due to increased fraud risk
Solution Approach 1:
The patent applies dynamics by making the pairing request phase duration adjustable rather than fixed. The external entity can dynamically set the duration parameter based on security requirements, allowing the system to adapt between permanent pairing (high ease of operation) and limited-time pairing (high security) depending on the specific use case and risk assessment.
2Reliability
If the pairing request phase is limited in time, then security is improved, but ease of operation deteriorates due to user action requirements
Solution Approach 1:
The patent applies self-service by enabling the external entity to automatically manage the pairing request phase without requiring continuous user intervention. The external entity autonomously detects pairing requests, monitors elapsed time, and automatically terminates the phase when the duration is reached, eliminating the need for users to manually activate or deactivate pairing modes.
3Ease of operation
If connection information is transmitted without security during pairing, then ease of operation is improved, but harmful factors increase due to vulnerability to fraud
Solution Approach 1:
The patent applies the intermediary principle by introducing an external entity that mediates the pairing process between the data processing device and potential connecting devices. This intermediary monitors and controls the pairing request phase, managing connection information transmission security without requiring the end user to implement complex security measures, thus maintaining ease of operation while reducing fraud risk.
Data Source
AI summary
A method for managing a phase for requesting pairing of a data processing device. The method includes the following steps in an entity external to the data processing device: detecting a pairing request phase from the data processing device; obtaining an elapsed duration linked to the pairing request phase; and requesting termination of the pairing phase beyond a given duration.
