Simpler, Faster, and More Robust T-test Based Leakage Detection

A. Adam Ding and Cong Chen and Thomas Eisenbarth

Abstract

The TVLA procedure using the t-test has become a popular leakage detection method. To protect against environmental fluctuation in laboratory measurements, we propose a paired t-test to improve the standard procedure. We take advantage of statistical matched-pairs design to remove the environmental noise effect in leakage detection. Higher order leakage detection is further improved with a moving average method. We compare the proposed test with standard t-test on synthetic data and physical measurements. Our results show that the proposed tests are robust to environmental noise.
