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 …

Quantum computing is considered among the next big leaps in computer science. While a
fully functional quantum computer is still in the future, there is an ever-growing need to …

Many currently deployed public-key cryptosystems are based on the difficulty of the discrete
logarithm and integer factorization problems. However, given an adequately sized quantum …

This paper presents faster implementations of the lattice-based schemes Dilithium and
Kyber on the Cortex-M4. Dilithium is one of three signature finalists in the NIST post …

Quantum computers pose a threat to the security of communications over the internet. This
imminent risk has led to the standardization of cryptographic schemes for protection in a post …

In this paper, we propose a practical signature scheme based on the alternating trilinear
form equivalence problem. Our scheme is inspired by the Goldreich-Micali-Wigderson's zero …

Homomorphic Encryption (HE) allows performing specific algebraic computations on
encrypted data without the need for decryption. For this reason, HE is emerging as a strong …

CRYSTALS-Dilithium as a lattice-based digital signature scheme has been selected as a
finalist in the Post-Quantum Cryptography (PQC) standardization process of NIST. As part of …

Recent progress in quantum computers severely endangers the security of widely used
public-key cryptosystems and of all communication that relies on it. Thus, the US NIST is …

This paper proposes two architectures for the acceleration of Number Theoretic Transforms
(NTTs) using a novel Montgomery-based butterfly. We first design a custom NTT hardware …
