We study how to mitigate the effects of energy attacks in the batteryless Internet of Things (IoT). Battery-less IoT devices live and die with ambient energy, as they use energy harvesting to power their operation. They are employed in a multitude of applications, including safety-critical ones such as biomedical implants. Due to scarce energy intakes and limited energy buffers, their executions become intermittent, alternating periods of active operation with periods of recharging their energy buffers. Experimental evidence exists that shows how controlling ambient energy allows an attacker to steer a device execution in unintended ways: energy provisioning effectively becomes an attack vector. We design, implement, and evaluate a mitigation system for energy attacks. By taking into account the specific application requirements and the output of an attack detection module, we tune task execution rates and optimize energy management. This ensures continued application execution in the event of an energy attack. When a device is under attack, our solution ensures the execution of 23.3% additional application cycles compared to the baselines we consider and increases task schedulability by at least 21%, while enabling a 34% higher peripheral availability.

“…In [3], a security issue related to context saving was introduced. The need for security in many emerging IoT applications is in contrast to existing context saving techniques that expose the content of the internal registers of the CPU to an external NVM without implementing security criteria.…”

IoT devices for low power applications often rely on energy harvesting techniques. In these implementations, IoT nodes must be aware of the amount of available energy. When the energy is about to run out, they need to halt and save the context of the CPU, which is restored as soon as the energy is available again. Some of the existing techniques rely on the transfer of the scan chains content to a Non-Volatile Memory (NVM). However, the saved state of the device might be the target of malicious attacks, including tampering and theft of confidential data. One solution is to provide the encryption and the integrity of context data. In this paper, we propose the implementation of an additional module interposed between the CPU and the NVM, which provides both these security features.
