SMARM+: Analyzing and Enhancing Shuffled Measurements for Remote Attestation in Real-Time IoT Settings
This work presents the first systematic study of SMARM in real-time RTOS-based setups, implements SMARM on commodity ARM TrustZone-M hardware running FreeRTOS and Zephyr, and introduces the Frequency Accuracy Ratio to quantify the extent to which attestation can coexist with real-time execution under varying workloads.
