| description | Subject of study. The paper presents the results of the experimental study of a wavelet-based pre-processing that was used to
increase the amount of statistically-discoverable information leakage in a side-channel signal. The studied signal was acquired via an electromagnetic channel of the ARM-Cortex M4F processor. The signal was recorded at the distance of 1 mm and 3 cm.
During signal collection, the Advanced Encryption Standard (AES) algorithm was executed on the board. Method. After the
acquisition, electromagnetic signal is processed using a discrete wavelet transform with shrinkage of the detail coefficients. The
influence of various shrinkage thresholds, mother wavelet, and wavelet decomposition level is studied. After processing of the
signal records, the leakage analysis is performed using the Test Vector Leakage Assessment (TVLA), a method based on the
Welch statistical test. The obtained estimates are used to compare wavelet transform pre-processing with the leakage estimate
of the original signal. Main Results. The signal processed by a wavelet transform shows higher values of the statistical test,
that means more confidence in the presence of an information leakage. The universal threshold and zeroing detail coefficients
increase the value of the t-criterion by 1.4 times. The third level of decomposition shows the highest result for all wavelet
functions. The discrete wavelet of Meyer shows the best result in all experiments. Symlets and Coiflets also show stable results
in the experiments. Practical Relevance. Statistical methods, such as the Welch statistical test, can detect leakage without costly
and time-consuming stages such as research and attacks. The wavelet transform and processing of the received signal increases
the informational components of the signal providing close-to-real statistical signal profiles. Pre-processing based on wavelet
transform also allows for leakage detection on fewer signal records. |
