Title: Challenges in High-Performance Cryptographic Hardware Design
Abstract:

Cryptography forms the foundation of trust in secure information exchange and is becoming increasingly important across diverse domains, including communications, finance, manufacturing, and medical devices. While cryptographic algorithms themselves are essential, practical systems often require both high performance and robust security.

In addition, as cryptographic standards continue to evolve, platform hardware must remain adaptable, highlighting the need for reconfigurable architectures.

This keynote will primarily focus on accelerating elliptic curve cryptography (ECC), one of the most widely used public-key schemes, using Field-Programmable Gate Array (FPGA) devices. The talk will review the key requirements for cryptographic hardware, including security strength and resistance to side-channel attacks, and then present techniques developed by the speaker to achieve high-speed ECC hardware implementations.

Finally, the keynote will address current challenges and future perspectives, including the design challenges associated with supporting post-quantum cryptography.

Dr. Wouter Castryck

Research group COSIC, KU Leuven

Research areas: Computational aspects of algebraic geometry and number theory, with a focus on cryptographic applications (isogeny-based cryptography, multivariate cryptography, lattice-based cryptography).

Title: Isogeny-based cryptography: an overview of the current landscape.

Abstract:
Isogeny-based cryptography is an elliptic-curve-based branch of public-key cryptography that, unlike classical ECC, is believed to offer security against quantum adversaries. It was developed almost completely during the past 15 years, so it concerns a young branch, but it seems to offer features that other approaches to post-quantum cryptography do not. In this talk, we will discuss the current state of this rapidly evolving field: why do we believe in its security, what cryptographic constructions does it allow, and what are the unique selling points of these constructions?

DR. FLORIAN CAULLERY

Director SoC Security | Cryptographer at the Technoloy Innovation Institute (TII) in Abu Dhabi, UAE

Research areas: range from pure mathematics to practical cryptography, with a strong focus on post-quantum cryptography, rank-based encryption schemes, and side-channel resistance for secure systems.

Title: One Chip, Many Engines: Accelerating and Securing cryptographic algorithms on modern SoCs

Abstract:

System-on-Chip (SoC) forms the foundation of today’s computing landscape, from servers, mobile phones, to IoT devices. Modern SoCs integrate a wide range of compute engines – CPUs, DSPs, GPUs, NPUs, and hardware cryptographic engines – each offering new opportunities to accelerate cryptographic workloads outside of the main CPUs. This heterogeneity opens promising paths for improving performance, but it also raises questions that have received relatively little attention from the academic community. In particular:

What are the advantages of offloading cryptographic operations from CPUs, not only in terms of speed but also power efficiency?
How can sensitive keys be securely shared across multiple compute units with different trust levels?
What unique challenges do heterogeneous SoCs pose for side-channel and fault-injection protections?

This keynote will survey current industry practices and case studies while highlighting open research opportunities.
