SUMMARY:PhaseSCA: Exploiting Phase-Modulated Emanations in Side Channels
DESCRIPTION:In recent years\, the limits of electromagnetic side-channel
 attacks have been significantly expanded. However\, the discovery of new
 fundamental phenomena about compromising electromagnetic emanations remains
 limited. In this presentation\, we examine work that identifies a novel
 form of modulation produced by unintentional electromagnetic emanations:
 phase-modulated emanations. This observation enables the extraction of a
 side-channel leakage that can be exploited to reveal secret cryptographic
 material. We introduce a technique allowing us to exploit this side-channel
 in order to perform a full AES key recovery\, using cost-effective and
 common hardware equipment like a software-defined radio (SDR).
 Additionally\, we discuss the consequences of this finding - which
 significantly improves attacks performance - and analyze its root
 cause.\nBio\nPierre Ayoub is specialized into low-level computer and radio
 security\, currently working at LAAS-CNRS in Toulouse (France) as a
 postdoctoral researcher on wireless and IoT security. He obtained his PhD
 in 2024 at EURECOM in Sophia-Antipolis (France)\, under the supervision of
 Aurélien Francillon\, Clémentine Maurice and Romain Cayre. He focused on
 novel electromagnetic side-channel attacks\, such as Screaming Channels and
 its security implications for IoT protocols like the Bluetooth Low Energy\,
 and electromagnetic emanations characterization and exploitation.
