Pattern-Driven Sensor Authentication for IoT Gateways
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices are vulnerable to remote threats and man-in-the-middle attacks due to their connectivity, which can lead to resource-intensive authentication processes and denial of service attacks, especially when dealing with a large number of IoT sensors.
Innovation Solution
Implementing an IoT prioritized sensor authentication management system that compares received data packets to pre-defined patterns or averages, quarantining packets that deviate significantly, and performing authentication only for prioritized sensors, thereby reducing unnecessary authentication processes and mitigating malicious spoofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password protection is implemented for every IoT sensor value, then security against man-in-the-middle attacks is improved, but resource consumption and processing time increase substantially
Solution Approach 1:
The patent applies local quality by implementing differentiated authentication: high-priority sensors receive full password protection while low-priority sensors use simplified validation. This selective approach maintains security where needed while reducing resource consumption for non-critical sensors, directly resolving the contradiction between comprehensive security and resource efficiency.
Solution Approach 2:
The patent segments sensors into priority groups (high and low) and applies different authentication mechanisms to each segment. High-priority sensors undergo full password verification while low-priority sensors use lighter validation, thereby reducing overall resource consumption while maintaining security for critical devices.
2Reliability
If password protection is implemented for every IoT sensor value, then security against man-in-the-middle attacks is improved, but the system becomes vulnerable to denial of service attacks
Solution Approach 1:
By applying password protection selectively only to high-priority sensors rather than uniformly to all sensors, the system maintains security for critical devices while avoiding DoS vulnerability. Low-priority sensors use simplified validation that does not burden the gateway, preserving system availability and preventing DoS attacks.
Solution Approach 2:
The segmentation of sensors by priority level creates different processing paths: high-priority sensors get secure but resource-intensive authentication, while low-priority sensors use fast validation. This prevents malicious actors from overwhelming the gateway with authentication requests from low-priority devices, thus preventing DoS attacks while maintaining security where needed.
3Reliability
If authentication is performed for all sensors, then security is improved, but processing time and resource intensity increase
Solution Approach 1:
The patent applies full authentication processing only to high-priority sensors where security is critical, while low-priority sensors receive expedited validation. This localized approach to authentication quality reduces overall processing time while maintaining security for devices where it matters most.
Data Source
AI summary
Internet-of-Things (IoT) prioritized sensor authentication management includes receiving in an IoT gateway different packets of data from different sensors over a computer communications network. For each received packet of data from a corresponding one of the different sensors, the received packet of data is compared to a pattern associated with the corresponding one of the different sensors. On the condition that the received packet of data is within a threshold of similarity to the pattern, a sensor value may be extracted from the received packet of data and transmitted to a sensor monitor. But otherwise, the received packet of data is placed into quarantine in memory of the IoT gateway, authentication of the corresponding one of the different sensors is performed, and in response to the authentication, the packet is released from quarantine, the sensor value extracted from the received packet of data and transmitted to the sensor monitor.
