This dataset was created to develop and test firmware attestation techniques for embedded IoT swarms using Static Random Access Memory (SRAM). It contains sequential, synchronous SRAM traces collected from four-node and six-node IoT swarms of devices, each with a 2KB SRAM. Each device is loaded with "normal" or "tampered" firmware to create different network scenarios. Swarm-1 is a four-node network encompassing thirteen scenarios, including two normal network states, two physical twin states, and nine anomalous states.
