The workshop takes place on Thursday September 18, 2025 in Meeting Room 306, afternoon (2:00 PM to 5:30 PM, local time). The venue is in the same building as CHES, but a separate registration to the CHES-affiliated event (PROOFS) is mandatory.
Abstract: Masking, a.k.a. "MPC on silicon", is a popular counter-measure against side-channel analysis of cryptographic hardware, by operating the computations over a secret sharing of sensitive data. Though masking was designed in the late 1990s as an ad hoc counter-measure, the research community has been able to establish since the 2010s its provable security, as a universal counter-measure. This presentation aims at giving a summary of the state of the art, and the many challenges remaining to address.
Bio: Loïc Masure is a CNRS researcher (since October 2023) at LIRMM (Univ. Montpellier). He holds a PhD in computer science from Sorbonne Université obtained in 2020, and prepared into the CEA-Leti ITSEF at Grenoble, supervised by Emmanuel Prouff (then at ANSSI, now at Apple), and Cécile Dumas (CEA - Leti). He has also been a postdoc researcher in the Crypto Group of UCLouvain, under the supervision of Prof. François-Xavier Standaert. His research revolves around the study of side-channel analysis against implementations of cryptographic primitives, and the use of machine learning to implement these attacks.
