Attack oriented traces filtering #31

Open samiBendou opened 4 years ago

samiBendou commented 4 years ago

Current behavior

A performant trace filtering is provided only for software traces

Expected behavior

Adapt filtering to sampling and crypto frequencies
Adapt filtering to software and hardware encryptions
Reduced number of traces required for attack

current filtering used on hardware traces : 13KHz butterworth high pass filter

Remove continuous component
Remove low frequency components
Seems to improve the correlation results

@Remote-HWA n'hésite pas à me donner d'autres paramètres de filtrage afin que je puisse vérifier si l'attaque nécessite moins de trace. J'aimerais notamment savoir comment tu filtres les traces software.
