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-Kyber has been selected by the NIST as a public-key encryption and key
encapsulation mechanism to be standardized. It is also included in the NSA's suite of …

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 …

Side-channel attacks are formidable threats to the cryptosystems deployed in the real world.
An effective and provably secure countermeasure against side-channel attacks is masking …

This paper questions the side-channel security of central reduction technique, which is
widely adapted in efficient implementations of Lattice-Based Cryptography (LBC). We show …

The main protection against side-channel attacks consists in computing every function with
multiple shares via the masking countermeasure. For IND-CCA secure lattice-based …

We present novel and improved high-order masking gadgets for Dilithium, a post-quantum
signature scheme that has been standardized by the National Institute of Standards and …

Over the last years, the side-channel analysis of Post-Quantum Cryptography (PQC)
candidates in the NIST standardization initiative has received increased attention. In …

The lattice-based CRYSTALS-Dilithium signature scheme has been selected for
standardization by the NIST. As part of the selection process, a large number of …

Lattice-based cryptography has laid the foundation of various modern-day cryptosystems
that cater to several applications, including post-quantum cryptography. For structured lattice …
