The advent of quantum computing threatens to break many classical cryptographic
schemes, leading to innovations in public key cryptography that focus on post-quantum …

Blockchain technology provides efficient and secure solutions to various online activities by
utilizing a wide range of cryptographic tools. In this article, we survey the existing literature …

We present a much-improved practical protocol, based on the hardness of Module-SIS and
Module-LWE problems, for proving knowledge of a short vector s→ satisfying A s→= t→ mod …

At IEEE Security & Privacy 2015, Bos, Costello, Naehrig, and Stebila proposed an
instantiation of Peikert's ring-learning-with-errors–based (Ring-LWE) key exchange protocol …

We propose a new class of post-quantum digital signature schemes that:(a) derive their
security entirely from the security of symmetric-key primitives, believed to be quantum …

Abstract The Fiat-Shamir transform is a technique for combining a hash function and an
identification scheme to produce a digital signature scheme. The resulting scheme is known …

We construct efficient ring signatures (RS) from isogeny and lattice assumptions. Our ring
signatures are based on a logarithmic OR proof for group actions. We instantiate this group …

In this paper, we present the lattice-based signature scheme Dilithium, which is a
component of the CRYSTALS (Cryptographic Suite for Algebraic Lattices) suite that was …

The lattice-based CRYSTALS-Dilithium scheme is one of the three thirdround digital
signature finalists in the National Institute of Standards and Technology Post-Quantum …

We present a practical construction of an additively homomorphic commitment scheme
based on structured lattice assumptions, together with a zero-knowledge proof of opening …
