    Itamar Levi

In this seminar I will first discuss unique computer aided design (CAD) compatible SCA security mechanisms. I will present an approach which can significantly increase the physical security-level of a design, be implemented with conventional design-tools and which does not require any special technological-support. The method consists with a correct by-design utilization of power-management libraries and tools; it embeds special and ultra low-cost randomization mechanisms in a local fashion into the RTL of a design. Therefore, making it mature and easy to master by any backend/frontend digital designer. This method is ideally suited for high security levels when used as a building block to reduce the SNR and amplify the noise in the leakage with mathematical solutions (e.g. masking). Theoretically, a limitation of the construction as a stand-alone is security-energy scaling, i.e. for very high security levels its energy cost is exponential. I will present a glimpse of our current work answering this challenge with an alternative construction which provide linear cost.
In the second part of the talk, I will discuss the threat of externally amplified coupling (EAC) attacks. A type of attack which is very dangerous for masked designs as it merges shares leakage which are otherwise supposed to be independent (weather hardware or software). I will review some of our work on the topic and will discuss the scalability of EAC attacks to high order masking designs, its dominance as compared to inherent (intra device) coupling and I will show some results from current experimentation with a dedicated ASIC test bad. Interestingly, the first and second part of the talk share a link which will be discussed.

    Le mécanisme d'encapsulation de clé Classic McEliece faisait partie des candidats toujours en lice au dernier tour du processus de standardisation de la cryptographie post-quantique initié par le NIST en 2016. Fondé sur les codes correcteurs d'erreurs, en particulier autour du cryptosystème de Niederreiter, sa sécurité n'a pas été fondamentalement remise en cause. Néanmoins, un aspect important du[…]

    Deep neural networks (DNNs) undergo lengthy and expensive training procedures whose outcome - the DNN weights - represents a significant intellectual property asset to protect. Side-channel analysis (SCA) has recently appeared as an effective approach to recover this confidential asset of DNN implementations. Ding et al. (HOST’25) introduced MACPRUNING, a novel SCA countermeasure based on pruning,[…]

    Dans la quête permanente d'une puissance de calcul plus rapide, les processeurs modernes utilisent des techniques permettant d'exploiter au maximum leurs ressources. Parmi ces techniques, l'exécution spéculative tente de prédire le résultat des instructions dont l'issue n'est pas encore connue, mais dont dépend la suite du programme. Cela permet au processeur d'éviter d'être inactif. Cependant,[…]

    Two major changes are currently taking place in the embedded processor ecosystem: open source with the RISC-V instruction set, which could replace the ARM one, and post-quantum cryptography (PQC), which could replace classic asymmetric cryptography algorithms to resist quantum computers.In this context, this thesis investigates the improvement of embedded processor performance, generally for[…]

    Embedded programs (including those on smart cards) are often developed in C and then compiled for the embedded processor. Sometimes they are modified by hand to incorporate countermeasures (fault attacks, etc.), but care must be taken to ensure that this does not disrupt normal program execution and that the countermeasure is actually adequate for blocking the attacks.In the process, it is[…]
