MPyC: Multiparty Computation in Python

Coconut: Threshold Issuance Selective Disclosure Credentials with Applications to Distributed Ledgers.

A simple Python implementation of threshold BLS signatures.

Naive implementation of ROAST protocol for robust threshold signatures

Minimalistic implementation of a Verifiable (t, n) threshold signature scheme based on elliptic curve with python.

A scheme that produces a zero-knowledge proof of correctness for an MPC computation. The scheme allows anyone, particularly someone external to the secure computation, to check the correctness of the output, while preserving the privacy properties of the MPC protocol.

This is the repository containing the information and code regarding secure e voting website Version_1

The repository of the EnGINE framework used for reproducible large scale experiments.

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.

Secret sharing

Pure Python implementation of the homomorphic encryption BFV scheme with support for multi-party thresholded operations

Shamir's secret sharing

Source-codes (with examples) to get threshold implementations for a given SBox

A Python implementation of threshold ECDSA using Shamir's Secret Sharing for secure multi-party computation. Features include secure channels, comprehensive testing, and a modular architecture for educational purposes.

Backend for threshold cryptography as a service using Shamir's Secret Sharing Scheme.
