LFDT - Implement DKLs23 (threshold ECDSA) protocol

About the Organization

<p>In standard cryptography, a single compromised key means total failure. Threshold Signing Schemes (TSS) mitigate this by distributing "shares" of a key across&nbsp;n&nbsp;participants, requiring a minimum threshold&nbsp;t&nbsp;participants to engage into the protocol to generate a signature. While the Lockness ecosystem already has a CGGMP24, a threshold ECDSA protocol, the&nbsp;<a href="https://eprint.iacr.org/2023/765.pdf" rel="noopener noreferrer" target="_blank" style="color: rgb(9, 105, 218);">DKLs23</a>&nbsp;protocol presents different features and performance, and unlocks new use-cases.</p><p><br></p><p>In this project, your goal is to transform a formal description of the protocol from the&nbsp;<a href="https://eprint.iacr.org/2023/765.pdf" rel="noopener noreferrer" target="_blank" style="color: rgb(9, 105, 218);">DKLs23 paper</a>&nbsp;into the code utilizing&nbsp;<code style="color: rgb(9, 105, 218); background-color: rgba(129, 139, 152, 0.12);"><a href="https://docs.rs/round-based/latest/round_based/" rel="noopener noreferrer" target="_blank">round-based</a></code>, a framework for TSS protocols, and&nbsp;<code style="color: rgb(9, 105, 218); background-color: rgba(129, 139, 152, 0.12);"><a href="https://docs.rs/generic-ec/latest/generic_ec/" rel="noopener noreferrer" target="_blank">generic-ec</a></code>, a type-safe library for elliptic-curve arithmetics.</p><p><br></p><h3>Learning Objectives</h3><ul><li>Deep Dive into MPC &amp; Threshold Primitives: Transition from theoretical knowledge of cryptography to implementing complex Multi-Party Computation (MPC) protocols, and gain a first-hand understanding of how&nbsp;t-out-of-n&nbsp;security is maintained mathematically.</li><li>Rust Development in the Lockness Ecosystem: Master high-performance, memory-safe programming by contributing to the Lockness ecosystem, specifically using the&nbsp;<code style="color: rgb(9, 105, 218); background-color: rgba(129, 139, 152, 0.12);"><a href="https://github.com/LFDT-Lockness/generic-ec" rel="noopener noreferrer" target="_blank">generic-ec</a></code>&nbsp;library for efficient and type-safe elliptic curve operations.</li><li>Modern Distributed Programming:&nbsp;Learn to write asynchronous code via the&nbsp;<code style="color: rgb(9, 105, 218); background-color: rgba(129, 139, 152, 0.12);"><a href="https://github.com/LFDT-Lockness/round-based" rel="noopener noreferrer" target="_blank">round-based</a></code>&nbsp;framework to manage complex network interactions.</li><li>From Paper to Production:&nbsp;Develop the ability to translate academic research into reliable, auditable, high-quality code, bridging the gap between "whitepaper math" and "real-world software".</li><li>Production-Grade Workflow:&nbsp;Experience a professional development lifecycle where cryptographic code is subject to rigorous peer reviews and testing to ensure maximum security.
