+ +## Overview +DKLs23 is an advanced open-source implementation of the Threshold ECDSA method (see https://eprint.iacr.org/2023/765.pdf). The primary goal of DKLs23 is to compute a secret key without centralizing it in a single location. Instead, it leverages multiple parties to compute the secret key, with each party receiving a key share. This approach enhances security by eliminating single points of failure. + +## Getting Started +These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. + +### Installation +A step-by-step guide to installing the project. + +1. **Install Rust using `rustup`** +``` bash +curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh +``` + +2. **Clone the repository:** +```bash +git clone https://github.com/0xCarbon/DKLs23 cd DKLs23 +``` + +3. **Install dependencies:** +```bash +cargo build +``` + +## Contributing +We welcome contributions!

Protocols for refreshing key shares when wanted/needed. +//! +//! This file implements a refresh protocol: periodically, all parties +//! engage in a protocol to re-randomize their secret values (while, of +//! course, still maintaining the same public key). +//! +//! The most direct way of doing this is simply executing DKG and restricting +//! the possible random values so that we don't change our address. We +//! implement this procedure under the name of "complete refresh". +//! +//! DKG also initializes the multiplication protocol, but we may take +//! advantage of the fact the we have already initialized this protocol +//! before. If we use this data for refresh, we don't need to execute +//! the OT protocols and we may save some time and some rounds. This +//! approach is implemented in another refresh protocol. +//! +//! ATTENTION: The protocols here work for any instance of Party, including +//! for derived addresses. However, refreshing a derivation is not such a +//! good idea because the refreshed derivation becomes essentially independent +//! of the master node. We recommend that only master nodes are refreshed +//! and derivations are calculated as needed afterwards. +//! +//! # Complete refresh +//! +//! In this case, we recompute all data from the parties. Hence, we essentially +//! rerun DKG but we force the final public key to be the original one. +//! +//! To adapt the DKG protocol, we change [Step 1](super::dkg::step1): instead of sampling any random +//! polynomial, each party generates a polynomial whose constant term is zero. +//! In this way, the key generation provides each party with a point on a polynomial +//! whose constant term (the "secret key") is zero. This new point is just a correction +//! factor and must be added to the original `poly_point` variable. This refreshes each +//! key share while preserving the same public key. +//! +//! Each party cannot trust that their adversaries really chose a polynomial +//! with zero constant term. Therefore, we must add a new consistency check in +//! [Phase 4](super::dkg::phase4): after recovering the auxiliary public key, each party must check that +//! it is equal to the zero point on the curve. This ensures that the correction +//! factors will not change the public key. +//! +//! # A faster refresh +//! +//! During a complete refresh, we initialize the multiplication protocol +//! from scratch. Instead, we can use our previous data to more efficiently +//! refresh this initialization. This results in a faster refresh and, +//! depending on the multiplication protocol, fewer communication rounds. +//! +//! We will base this implementation on the article "Refresh When You Wake Up: +//! Proactive Threshold Wallets with Offline Devices" () +//! More specifically, we use their ideas from Section 8 (and Appendix E). +//! +//! In their protocol, a common random string is sampled by each pair of +//! parties. They achieve this by using their "coin tossing functionality". +//! Note that their suggestion of implementation for this functionality is +//! very similar to the way our zero shares protocol computes its seeds. +//! +//! Hence, our new refresh protocol will work as follows: we run DKG +//! ignoring any procedure related to the multiplication protocol (and we +//! do the same modifications we did for the complete refresh). During +//! the fourth phase, the initialization for the zero shares protocol +//! generates its seeds. We reuse them to apply the Beaver trick (described +//! in the article) to refresh the OT instances used for multiplication. +//! +//! # Nomenclature +//! +//! For the messages structs, we will use the following nomenclature: +//! +//! **Transmit** messages refer to only one counterparty, hence +//! we must produce a whole vector of them. Each message in this +//! vector contains the party index to whom we should send it. +//! +//! **Broadcast** messages refer to all counterparties at once, +//! hence we only need to produce a unique instance of it. +//! This message is broadcasted to all parties. +//! +//! ATTENTION: we broadcast the message to ourselves as well! +//! +//! **Keep** messages refer to only one counterparty, hence +//! we must keep a whole vector of them. In this implementation, +//! we use a `BTreeMap` instead of a vector, where one can put +//! some party index in the key to retrieve the corresponding data. +//! +//! **Unique keep** messages refer to all counterparties at once, +//! hence we only need to keep a unique instance of it. + +use std::collections::BTreeMap; + +use elliptic_curve::bigint::U256; +use elliptic_curve::ops::Reduce; +use elliptic_curve::CurveArithmetic; +use elliptic_curve::{Field, PrimeField}; +use serde::{Deserialize, Serialize}; + +use crate::utilities::hashes::{hash, HashOutput}; +use crate::utilities::multiplication::{MulReceiver, MulSender}; +use crate::utilities::ot; +use crate::utilities::rng; +use crate::utilities::zero_shares::{self, ZeroShare}; +use crate::DklsCurve; + +use crate::protocols::derivation::DerivData; +use crate::protocols::dkg::{ + step2, step3, step5, KeepInitMulPhase3to4, KeepInitZeroSharePhase2to3, + KeepInitZeroSharePhase3to4, ProofCommitment, TransmitInitMulPhase3to4, + TransmitInitZeroSharePhase2to4, TransmitInitZeroSharePhase3to4, +}; +use crate::protocols::{Abort, PartiesMessage, Party}; + +// STRUCTS FOR MESSAGES TO TRANSMIT IN COMMUNICATION ROUNDS. + +// "Transmit" messages refer to only one counterparty, hence +// we must send a whole vector of them. + +/// Transmit - (Faster) Refresh. +/// +/// The message is produced/sent during Phase 2 and used in Phase 4. +#[derive(Clone, Serialize, Deserialize, Debug)] +pub struct TransmitRefreshPhase2to4 { + pub parties: PartiesMessage, + pub commitment: HashOutput, +} + +/// Transmit - (Faster) Refresh. +/// +/// The message is produced/sent during Phase 3 and used in Phase 4. +#[derive(Clone, Serialize, Deserialize, Debug)] +pub struct TransmitRefreshPhase3to4 { + pub parties: PartiesMessage, + pub seed: zero_shares::Seed, + pub salt: Vec, +} + +// STRUCTS FOR MESSAGES TO KEEP BETWEEN PHASES. + +/// Keep - (Faster) Refresh. +/// +/// The message is produced during Phase 2 and used in Phase 3. +#[derive(Clone, Serialize, Deserialize, Debug)] +pub struct KeepRefreshPhase2to3 { + pub seed: zero_shares::Seed, + pub salt: Vec, +} + +/// Keep - (Faster) Refresh. +/// +/// The message is produced during Phase 3 and used in Phase 4. +#[derive(Clone, Serialize, Deserialize, Debug)] +pub struct KeepRefreshPhase3to4 { + pub seed: zero_shares::Seed, +} + +/// Implementations related to refresh protocols ([read more](self)). +impl Party +where + C::Scalar: Reduce + PrimeField, + C::AffinePoint: Default + elliptic_curve::group::GroupEncoding, +{ + // COMPLETE REFRESH + + /// Works as [Phase 1](super::dkg::phase1) in DKG, but with + /// the alterations needed for the refresh protocol. + /// + /// The output should be dealt in the same way. + #[must_use] + pub fn refresh_complete_phase1(&self) -> Vec { + // We run Phase 1 in DKG, but we force the constant term in Step 1 to be zero. + + // DKG + let mut secret_polynomial: Vec = + Vec::with_capacity(self.parameters.threshold as usize); + secret_polynomial.push(C::Scalar::ZERO); + for _ in 1..self.parameters.threshold { + secret_polynomial.push(C::Scalar::random(rng::get_rng())); + } + + step2::(&self.parameters, &secret_polynomial) + } + + /// Works as [Phase 2](super::dkg::phase2) in DKG, but the + /// derivation part is omitted. + /// + /// The output should be dealt in the same way.

Extension protocol. +//! +//! This file implements an Oblivious Transfer Extension (OTE) that realizes +//! Functionality 3 in `DKLs19` (). It is +//! used for the multiplication protocol (see multiplication.rs). +//! +//! As `DKLs23` suggested, we use Roy's `SoftSpokenOT` (). +//! However, we do not follow this paper directly. Instead, we use the `KOS` paper +//! available at . In the corrected version, +//! they present an alternative for their original protocol (which was used by `DKLs`, +//! but was not as secure as expected) using `SoftSpokenOT` (see Fig. 10 in `KOS`). +//! +//! In order to reduce the round count, we apply the Fiat-Shamir heuristic, as `DKLs23` +//! instructs. We also include an additional step in the protocol given by `KOS`. It +//! comes from Protocol 9 of the `DKLs18` paper (). +//! It is needed to transform the outputs to the desired form. +//! +//! # Remark: the OT width +//! +//! We implement the "forced-reuse" technique suggested in `DKLs23`. +//! As they say: "Alice performs the steps of the protocol for each input in +//! her vector, but uses a single batch of Bob's OT instances for all of them, +//! concatenating the corresponding OT payloads to form one batch of payloads +//! with lengths proportionate to her input vector length." +//! +//! Actually, this approach is implicitly used in `DKLs19`. This can be seen, +//! for example, in the two following implementations: +//! +//! +//! +//! +//! +//! In both of them, the sender supplies a vector of 2-tuples of correlations against +//! a unique vector of choice bits by the receiver. This number "2" is called in the +//! first implementation as the "OT width". We shall use the same terminology. Here, +//! instead of taking a vector of k-tuples of correlations, we equivalently deal with +//! k vectors of single correlations, where k is the OT width. + +use elliptic_curve::bigint::U256; +use elliptic_curve::group::GroupEncoding; +use elliptic_curve::ops::Reduce; +use elliptic_curve::PrimeField; +use rand::Rng; +use serde::de::Error; +use serde::{Deserialize, Deserializer, Serialize, Serializer}; + +use crate::DklsCurve; +use crate::{RAW_SECURITY, STAT_SECURITY}; + +use crate::utilities::hashes::{hash, hash_as_scalar, HashOutput}; +use crate::utilities::proofs::{DLogProof, EncProof}; +use crate::utilities::rng; + +use crate::utilities::ot::base::{OTReceiver, OTSender, Seed}; +use crate::utilities::ot::ErrorOT; + +// CONSTANTS +// You should not change these numbers!
