A Bulk Built-in Sensor for Detection of Fault Attacks
Abstract
This work presents a novel scheme of built-in current sensor (BICS) for detecting transient fault-based attacks of short and long duration as well as from different simultaneous sources. The new sensor is a single mechanism connected to PMOS and NMOS bulks of the monitored logic. The proposed protection strategy is also useful for improving any state-of-the-art Bulk-BICS from pairs of PMOS and NMOS sensors to single sensors.
