The Number Theoretic Transform (NTT) is a powerful mathematical tool that has become
increasingly important in developing Post Quantum Cryptography (PQC) and Homomorphic …

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 …

Quantum computing technologies pose a significant threat to the currently employed public-
key cryptography protocols. In this paper, we discuss the impact of the quantum threat on …

We present KEMTLS, an alternative to the TLS 1.3 handshake that uses key-encapsulation
mechanisms (KEMs) instead of signatures for server authentication. Among existing post …

Two multivariate digital signature schemes, Rainbow and GeMSS, made it into the third
round of the NIST PQC competition. However, neither made its way to being a standard due …

We consider all LWE-and NTRU-based encryption, key encapsulation, and digital signature
schemes proposed for standardisation as part of the Post-Quantum Cryptography process …

We present a new method for transforming zero-knowledge protocols in the designated
verifier setting into public-coin protocols, which can be made non-interactive and publicly …

Post-quantum cryptographic primitives have a range of trade-offs compared to traditional
public key algorithms, either having slower computation or larger public keys and …

MPC-in-the-head based zero-knowledge proofs allow one to prove knowledge of a
preimage for a circuit defined over a finite field F. In recent proofs the soundness depends …

Although they have been studied for a long time, distributed signature protocols have
garnered renewed interest in recent years in view of novel applications to topics like …
