User Equipment Time Location Indicator Binding for IoT Replay Attack Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices with limited connectivity, such as IoT devices, face challenges in associating measurement data with current time and location values, especially when they lack the capability to determine these values locally, and are vulnerable to replay attacks during data transmission.
Innovation Solution
A method where a UE transmits an indicator of current time and location values to the wireless communication device, which acknowledges and forwards this information along with the measurement data to a data collector, using secure binding or signatures to mitigate replay attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless communication device relies on a UE to obtain current values of time and location, then the device can acquire time and location information without local capabilities, but the transmission becomes vulnerable to replay attacks
Solution Approach 1:
The UE transmits an indicator of current time and location values to the wireless communication device before the device sends its measurement data. This preliminary transmission allows the device to include these time and location indicators in its data transmission, enabling the data collector to verify the freshness and authenticity of the received data, thus preventing replay attacks while maintaining the adaptability of devices without local time and location capabilities
Solution Approach 2:
The UE acts as an intermediary that provides time and location information to the wireless communication device. The UE obtains current time and location values (potentially from network sources or its own capabilities) and relays this information to the device, which then forwards it along with measurement data to the data collector. This intermediary role enables secure data transmission without requiring the wireless device to have local time and location determination capabilities
2Productivity
If a UE caches measurement data and forwards it at a later time, then network coverage options are utilized effectively, but the association of current time and location values becomes more complex
Solution Approach 1:
The UE obtains and transmits the current time and location indicators to the wireless communication device before potentially caching the measurement data. When the UE later forwards the cached data to the data collector, it includes the previously transmitted time and location indicators, allowing the data collector to associate these values with the measurement data without requiring complex real-time tracking mechanisms at the UE
Solution Approach 2:
The UE creates a copy of the current time and location indicator values and transmits this copy to the wireless communication device. This copied information is then included with the measurement data when forwarded to the data collector, enabling accurate time and location association without requiring the UE to maintain or track the actual current values during the caching period, thus reducing device complexity

AI summary
Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes transmitting, to a wireless communication device, an indicator of current values of time and location obtained by the UE; receiving, from the wireless communication device, measurement data acquired at the wireless communication device and an acknowledgement of the indicator of the current values of time and location; and forwarding the measurement data and the acknowledgement of the indicator of the current values of time and location to a data collector. A method for wireless communication at a wireless communication device includes receiving, from a UE, an indicator of current values of time and location; and transmitting, to the UE, measurement data and an acknowledgement of the indicator of the current values of time and location.
