Virtual Triggering: a Technique to Segment Cryptographic Processes in Side Channel Traces. (arXiv:2210.12059v1 [cs.CR])

Side-Channel Attacks (SCAs) exploit data correla-tion in signals leaked from
devices to jeopardize confidentiality. Locating and synchronizing segments of
interest in traces from Cryptographic Processes (CPs) is a key step of the
attack. The most common method consists in generating a trigger signal to
indicate to the attacker the start of a CP. This paper proposes a method called
Virtual Triggering (VT) that removes the need for the trigger signal and
automates trace segmentation. When the time between repetitions is …
