Abstract The National Institute of Standards and Technology is in the process of selecting
publickey cryptographic algorithms through a public, competition-like process. The new …

CRYSTALS-Dilithium has been selected by the NIST as the new standard for post-quantum
digital signatures. In this work, we revisit the side-channel countermeasures of Dilithium in …

In this work, we present a systematic study of Side-Channel Attacks (SCA) and Fault
Injection Attacks (FIA) on structured lattice-based schemes, with main focus on Kyber Key …

In this work, we propose generic and novel adaptations to the binary Plaintext-Checking
(PC) oracle based side-channel attacks for Kyber KEM. These attacks operate in a chosen …

The emergence of quantum computing poses a formidable security challenge to network
protocols traditionally safeguarded by classical cryptographic algorithms. This paper …

Whereas theoretical attacks on standardized cryptographic primitives rarely lead to actual
practical attacks, the situation is different for side-channel attacks. Improvements in the …

Side-channel resilience is a crucial feature when assessing whether a postquantum
cryptographic proposal is sufficiently mature to be deployed. In this paper, we propose a …

NIST's PQC standardization process is in the third round, and a first final choice between
one of three remaining lattice-based key-encapsulation mechanisms is expected by the end …

In this work, we present the first fault injection analysis of the Number Theoretic Transform
(NTT). The NTT is an integral computation unit, widely used for polynomial multiplication in …

Abstract The Number Theoretic Transform (NTT) is a major building block in recently
introduced lattice based post-quantum (PQ) cryptography. The NTT was target of a number …
