MPC-TSS is a project to demonstrate the working of our threshold signature scheme leveraging the security of X1 hardware wallet

Python implementation of Class Group algorithms from Cohen (GTM 138)

CyChain is a non-collusive & massively decentralized access control network. This repository contains the working proof of concept to demonstrate it's scalability.

A scheme to implement finite groups as oblivious data structures. The oblivious operations are defined by a set of secure multiparty computation (MPC) protocols. Practical protocols are presented for the group of quadratic residues, elliptic curves groups and class groups of imaginary quadratic orders.
