Leak Resistant Architecture: Statements and Perspectives
Laboratoire d´Informatique, de Robotique e de Microélectronique de Montpellier (Jean-Claude Bajard) –
Hardware implementations of cryptographic algorithms may leak some information as computing time, electromagnetic emissions and power consumption. Based on this information, some kind of attacks can be performed to recover cryptographic keys. This presentation shows two approaches to thwart some Side Channel Attacks (SCA).
The first one is an analog hardware countermeasure that counteracts SCA that not requires any modification on the cryptographic algorithm, the messages or keys.
The second method concerns a combination of reconfigurable techniques with the recently proposed Leak Resistant Arithmetic (LRA) to thwart SCA based on power analysis. The main aim of this approach is to perform modular multiplication and exponentiation, the most significant cryptographic operations, by randomly change the intermediate results of a cryptographic computation. In this way SCA based on power analysis is no longer efficient. This approach resulted in a Leak Resistant Reconfigurable Architecture (LR²A).
Both method were simulated and synthesized for the CMOS 0.18µ technology.
A short version of the LR²A was prototyped in FPGA and a SCA attack was performed to show the efficiency of the new architecture.

Workshop “Metabolism and mathematical models: Two for a tango” – 2nd Edition
Title: Workshop Metabolism and mathematical models: Two for a tango – 2nd Edition
Dates: October 25-26, 2022
Location: This workshop will be held in a virtual way
The topic of this workshop is metabolism in general, with a special focus, although not exclusive, on parasitology. Besides an exploration of the biological, biochemical and biomedical aspects, the workshop will also aim at presenting some of the mathematical modelling, algorithmic theory and software development that have become crucial to explore such aspects.
This workshop is being organised in the context of two projects, both with the Inria European Team Erable. One of the projects involves a partnership with the University of São Paulo (USP), in São Paulo, Brazil, more specifically the Institute of Mathematics and Statistics (IME) and the Institute of Biomedical Sciences – Inria Associated Team Capoeira – and the other involves the Inesc-ID/IST in Portugal, ETH in Zürich and EMBL in Heidelberg – H2020 Twinning Project Olissipo.
The workshop is open to all members of these two projects but also, importantly, to the community in general.
The program and more details are available here.
