Séminaire SemSecuElec : deux intervenants

Bonjour,

La prochaine session du séminaire sécurité des systèmes électroniques embarqués aura lieu le vendredi 28 Février de 10h à 12h.
Le séminaire aura lieu dans les locaux de l'Inria Rennes, Salle Aurigny.

Le programme de cette session est le suivant : 

• 10:00 - 11:00 - Díaz Rizo Alan (Sorbonne Université Lip6 )

  • Titre : Covert Communication Channels Based On Hardware Trojans: Open-Source Dataset and AI-Based Detection

  • Résumé : The threat of Hardware Trojan-based Covert Channels (HT-CCs) presents a significant challenge to the security of wireless communications. In this work, we generate in hardware and make open-source a dataset for various HT-CC scenarios. The dataset represents transmissions from a HT-infected RF transceiver hiding a CC that leaks information. It encompasses a wide range of signal impairments, noise levels, and HT insertions, facilitating a robust evaluation of HT-CC attack models and defenses. We also propose a deep learning-based HT-CC detection defense that achieves excellent accuracy on the dataset. It is an one fit all solution that circumvents the cost of integrating several distinct defenses to deal with all known HT-CC scenarios.

• 11:00 - 12:00 - GARAY Arturo (STMicroelectronics)

  • Titre : Measurement the thermal component of clock jitter used as entropy source by TRNGs

  • Résumé :

    Introduction

    • Measuring the thermal component of clock jitter as an entropy source for True Random Number Generators (TRNGs) is compulsory for the security and evaluation of clock-jitter based TRNGs. However, identifying and isolating the local thermal noise component from other noise sources, particularly flicker noise, while performing a precise measurement remains a challenge.

    Current Techniques

    • We present an overview of the most effective techniques currently available for measuring the thermal clock jitter component. However, even the best techniques may struggle to avoid the influence of flicker noise on their measurements. Consequently, their results risk representing an overestimation of the thermal jitter component.

    Characterizing Clock Jitter

    • We present state-of-the-art methods for distinguishing between flicker noise and thermal noise components of a random signal while introducing their problems when applied to the evaluation of TRNGs.

    Conclusion

    • Despite advancements, current clock jitter measurement techniques should be used cautiously
