Revisiting Keccak and Dilithium Implementations on ARMv7-M
Transactions on Cryptographic Hardware and Embedded SystemsKeccak is widely used in lattice-based cryptography (LBC) and its impact to the overall running time in LBC scheme can be predominant on platforms lacking dedicated SHA-3 instructions. This holds true on embedded devices for Kyber and Dilithium, two LBC

PUF-Dilithium: Design of a PUF-Based Dilithium Architecture Benchmarked on ARM Processors
ACM Transactions on Embedded Computing Systems, 2023 <p>In this paper, by taking advantage of physical unclonable functions (PUFs), we introduce a novel design that provides physical security to CRYSTALS-Dilithium. After discussing the advantages of our design compared to the original design, we implemented it on two different architectures, ARMv7 and ARMv8.

Exploiting Small-Norm Polynomial Multiplication with Physical Attacks
Transactions on Cryptographic Hardware and Embedded SystemsWe present a set of physical profiled attacks against CRYSTALS-Dilithium that accumulate noisy knowledge on secret keys over multiple signatures, finally leading to a full key recovery attack. The methodology is composed of two steps.
