Quantum computers are expected to break modern public key cryptography owing to Shor's
algorithm. As a result, these cryptosystems need to be replaced by quantum-resistant …

Blockchain and other Distributed Ledger Technologies (DLTs) have evolved significantly in
the last years and their use has been suggested for numerous applications due to their …

We introduce SPHINCS+, a stateless hash-based signature framework. SPHINCS+ has
significant advantages over the state of the art in terms of speed, signature size, and …

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 …

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 …

This document is the supporting documentation of Falcon. It is organized as follows. Chapter
2 explains the overall design of Falcon and its rationale. Chapter 3 is a complete …

Every attempt to access to the Internet through a Web browser, email sent, VPN connection,
VoIP call, instant message or other use of telecommunications systems involves …

Recent work, including ZKBoo, ZKB++, and Ligero, has developed efficient non-interactive
zero-knowledge proofs of knowledge (NIZKPoKs) for Boolean circuits based on symmetric …

Cryptography is essential for the security of online communication, cars and implanted
medical devices. However, many commonly used cryptosystems will be completely broken …

We give a new signature scheme for isogenies that combines the class group actions of
CSIDH with the notion of Fiat-Shamir with aborts. Our techniques allow to have signatures of …
