CARDIS 2021 is over. All pre-recordings and the recordings of the live sessions are now available on the CARDIS YouTube Channel.

CARDIS 2021 was accompanied by the Fall School on Nano-Electronics for Secure Systems (NESSY). NESSY is aimed at PhD students, postdocs and interested individuals and is supposed to offer the opportunity for networking, discussions, and collaboration. CARDIS 2021 and NESSY shared an invited talk.

CARDIS 2021 Keynote Speakers

Nele Mentens - Security challenges and opportunities in emerging device technologies: a case study on flexible electronics

Abstract While traditional chips in bulk silicon technology are widely used for reliable and highly efficient systems, there are applications that call for devices in other technologies. On the one hand, novel device technologies need to be re-evaluated with respect to potential threats and attacks, and how these can be faced with existing and novel security solutions and methods. On the other hand, emerging device technologies bring opportunities for building the secure systems of the future. This talk gives an overview of the minimal hardware resources that are needed to build secure systems and discusses a case study on flexible electronics on plastics. Bio Nele Mentens is a professor at Leiden University and KU Leuven. She was a visiting researcher at Ruhr University Bochum in 2013 and at EPFL in 2017. Her research interests are in the field of configurable computing and hardware security. She was/is the PI in around 20 finished and ongoing research projects with national and international funding. She serves as a program committee member of renowned international conferences on security and hardware design, such as NDSS, USENIX Security Symposium, ACM CCS, Asiacrypt, CHES, ESORICS, DAC, DATE, FPL and ESSCIRC. She was the general co-chair of FPL'17 and the program chair of EWME'18, PROOFS'18, FPL'20, CARDIS'20, RAW'21 and VLSID'22. She is (co-)author in over 100 publications in international journals, conferences and books. She received best paper awards and nominations at CHES'19, AsianHOST'17 and DATE'16. Nele serves as an associate editor for IEEE Transactions on Information Forensics and Security, IEEE Circuits and Systems Magazine, and IEEE Security and Privacy.

Christine van Vredendaal - Challenges of Post-Quantum Cryptography in the Embedded World

Abstract In this talk I will first give a short introduction to PQC and it's standardization process. I will then dive into various topics that make PQC particularly challenging for constrained devices. This starts with simple issues like the sizes of keys and signatures, and moves beyond that with challenges in (side-channel) cryptanalysis and side-channel countermeasures. Bio Christine van Vredendaal is a senior cryptographer at the Competence Center Crypto & Security of NXP Semiconductors. Before that she in 2018 completed a PhD in Dan Bernstein's Cryptographic Implementations group of TU Eindhoven on the topic of "Exploiting Mathematical Structures in Cryptography" with distinction. Since 2018 her work at NXP has covered various topics in the realm of Embedded Post-Quantum Cryptography, with a focus on Lattice- and Hash-based Cryptography.

Axel Poschmann - Lessons Learned from Securing the Supply Chain of a High Security Smartphone

Abstract Secure Elements have been an immense success story over the past decades and they are fundamental building blocks of high end secure systems. However, designing a high end security product rooted in high end hardware security proves more difficult, as the security of the supply chain is a major challenge. In this talk we will walk through the practical challenges that have to be overcome when securing the physical supply chain of a high security smartphone. Bio Dr. Axel Y. Poschmann is currently Head of xen1thLabs - the leading cyber security test and validation laboratory in the GCC region. Previously, he worked at NXP semiconductors in Hamburg, Germany on securing high security smart cards. Before that he was an assistant professor at NTU, Singapore. Axel is passionate about Product Security in general, and hardware and supply chain security in particular. He holds a PhD in electrical engineering and is currently pursuing an Executive MBA. He published more than 40 scientific articles with more than 8300 citations on lightweight crypto and cryptographic engineering and he is co-editor of 2 ISO standards on lightweight cryptography.
