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
The secure generation of parameters for zk-SNARKs is a crucial step in the trustworthiness of the resulting proof system. By highlighting some potential pitfalls and important security considerations of these implementations, NCC Group hopes to provide helpful pointers to all implementers and avoid the introduction of vulnerabilities detrimental to the confidence users have in the different applications of these systems.
