What do S-boxes Say in Differential Side Channel Attacks?

Cecile Canovas and Jessy Clediere

Abstract

Cryptographic devices are vulnerable against the now well-known side channel leakage analysis. Secret data, such as keys, can be revealed by attacks like DPA, DEMA, CPA. However, this kind of attacks also exhibits wrong keys, this phenomenon being known as the "ghost peaks" problem and has been brieﬂy explained in CPA. We give here a comprehension and analysis of the ghost peak problem that occurs in differential analysis regarding to different power consumption model and various weighting techniques.
