During the spring of 2020, Qredo engaged NCC Group Cryptography Services to conduct a security assessment of the Apache Milagro MPC library. This library implements the primitives necessary to instantiate the multi-party ECDSA signature scheme provided in Gennaro and Goldfeder’s Fast Multiparty Threshold ECDSA with Fast Trustless Setup. This assessment occurred over the course of … Continue reading Public Report – Qredo Apache Milagro MPC Cryptographic Assessment
This is the second of three code-centric blog posts on pairing based cryptography. The first post  covered modular arithmetic, finite fields, the embedding degree, and presented an implementation of a 12-degree prime extension field tower. The series will ultimately conclude with a detailed review of the popular BLS12-381 pairing operations found in a variety … Continue reading Pairing over BLS12-381, Part 2: Curves
