lattice-cryptography 0.0.3

Implementation of lattice cryptography primitives

Introduction

This repository contains an implementation of a lattice-based one-time signature scheme (similar to the one published by Lyubashevsky and Micciancio), and an extension to Boneh and Kim style signature aggregation. The lattice_cryptography folder also includes a prototype of our novel one-time adaptor signature scheme.

Explanatory resources

The "Techniques for efficient post-quantum finance" finance series contains several articles that go into detail about how these schemes work.
