Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G NR protocols lack effective security measures to prevent eavesdropping and unauthorized access to communications with IoT devices, particularly passive and semi-passive devices with limited energy storage capabilities, which are vulnerable due to their low power consumption and hardware limitations.
Innovation Solution
Implementing a network node that determines and transmits a jamming signal configuration to counter eavesdropping, using parameters such as time offset, waveform type, and transmission power, based on eavesdropping reports and energy harvesting capabilities of IoT devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing security protocols are implemented to prevent eavesdropping, then communication security is improved, but energy consumption increases significantly
Solution Approach 1:
The network node performs preliminary actions by transmitting jamming signals before and during the IoT device's communication with the base station. This preemptive interference prevents eavesdroppers from capturing useful information without requiring the IoT device to expend additional energy on complex security protocols. The jamming signal is configured in advance with parameters such as time offset, waveform type, and carrier frequency to effectively block eavesdropping attempts.
Solution Approach 2:
The network node acts as an intermediary between the IoT device and potential eavesdroppers. By introducing a controlled jamming signal through the network node, the system creates a protective interference field that blocks unauthorized access to communications. This intermediary approach allows security enhancement without directly increasing the energy burden on the battery-less or low-energy IoT device.
2Reliability
If jamming signals are transmitted to prevent eavesdropping, then security against unauthorized access is improved, but signal interference with legitimate communications may occur
Solution Approach 1:
The jamming signal is configured with specific local characteristics including time offset, waveform type, carrier frequency, and bandwidth that are tailored to target only the eavesdropping frequency resources. The network node adjusts these parameters to create localized interference in the specific time-frequency slots where eavesdropping is detected, while maintaining clarity of legitimate IoT-device-to-base-station communications.
Solution Approach 2:
The jamming signal configuration is dynamic and adaptive, adjusting parameters such as time offset and frequency pattern based on real-time detection of eavesdropping events. The network node modifies the jamming signal characteristics in response to detected eavesdropping probability and eavesdropped resources, allowing the system to respond flexibly to varying attack conditions while minimizing impact on legitimate communications.
3Adaptability or versatility
If network-initiated attachment procedure is used for passive IoT devices, then device connectivity is improved, but communication latency increases
Solution Approach 1:
The network node performs preliminary actions by pre-configuring jamming signal parameters and detecting eavesdropping conditions before the main communication data transmission begins. This allows the network to establish secure communication channels in advance for passive IoT devices, enabling network-initiated attachment without significant latency delays. The preliminary detection and configuration of security measures occurs during the setup phase, before time-sensitive data transmission.
