Abstract
Microprobing is commonly used to extract firmware dumps or cryptographic keys from microcontrollers. We introduce the Calibratable Lightweight Invasive Attack Detector (CaLIAD) to detect microprobing attacks. The CaLIAD measures timing imbalances between lines that are caused by the capacitive load of a probe. Compared to protection mechanisms from industry, it does not require an additional protection layer such as meshes do; in contrast to bus encryption, it does not introduce delay cycles. Co...
