Multiplication-to-Addition (MtA) Protocol Implementation

This implements a secure two-party protocol that converts multiplication into addition.
The protocol allows two parties with private inputs a and b to compute additive shares
s1 and s2 such that s1 + s2 = a * b mod q, without revealing their inputs to each other.

The MtA protocol is a fundamental building block in multi-party computation (MPC) systems,
enabling secure multiplication operations in protocols like ECDSA threshold signatures.

P-256 Elliptic Curve Cryptography Utilities

This module provides a centralized implementation of P-256 elliptic curve
operations, constants, and utilities used across the MPC protocol implementations.
It eliminates code duplication and provides a consistent interface for all
ECC-related operations.

This module includes:
