Title:
ROPAD: A Fully Digital Highly Predictive Ring Oscillator Probing Attempt Detector 
Abstract:
Microprobing is an invasive attack technique to intercept data from on-chip signals. As a countermeasure, we propose a new probing detector for an industrial sub-40\; nm advanced process node. It is based on ring oscillators incorporating bus lines. The oscillation frequency caused by the capacity of bus lines is differentially measured to detect attached probes. This concept reduces calibration effort and required protected non-volatile memory in comparison to state of the art. Furthermore, the...    »
