Transient Effect Ring Oscillators Leak Too
Transient effect ring oscillator electromagnetic leaks side-channel analysis
font style='font-size:12px;'>
2019/3/21
Up to now, the transient effect ring oscillator (TERO) seemed to be a better building block for PUFs than a standard ring oscillator, since it was thought to be immune to electromagnetic analysis. Her...

This paper proposes a theoretical study and a full overview of the design, evaluation and optimization of a PUF based on transient element ring oscillators (TERO-PUF). We show how, by following some s...
Synchronous Sampling and Clock Recovery of Internal Oscillators for Side Channel Analysis
side-channel analysis acquisition
font style='font-size:12px;'>
2014/3/13
Measuring power consumption for side-channel analysis typically uses an oscilloscope, which measures the data relative to an internal sample clock. By synchronizing the sampling clock to the clock of ...
