Mod sign Mnemonic

Overview

ModSignMnemonic is a module in the Veive protocol designed to validate signatures derived from mnemonic-based key pairs using the ECDSA (Elliptic Curve Digital Signature Algorithm) P-256 (ES256) standard. Mnemonic phrases are commonly used in blockchain systems to generate deterministic private keys, allowing users to sign transactions and authenticate securely. This module focuses on validating ECDSA signatures generated from mnemonic-derived keys, ensuring that only rightful account owners can authorize transactions.

Purpose

Mnemonic-based authentication leverages the ECDSA algorithm to create a secure digital signature using a private key derived from a 12-word mnemonic phrase. In blockchain applications, this signature serves as proof of ownership and authorizes transactions. The P-256 (ES256) standard provides a high level of security, making it a reliable choice for cryptographic authentication within the Veive ecosystem.

Key Components in Mnemonic Signature Validation:

Signature: A 65-byte string that consists of the actual signature and a recovery byte, which is used to derive the public key from the signature.
Public Key: The public portion of the key pair, which can be derived from the signature and used to verify the signature.
Transaction ID: A unique identifier for the transaction, used along with the signature to recover the public key.

How ModSignMnemonic Works

The ModSignMnemonic module is responsible for validating that a transaction is signed by the account it claims to be from. This process involves:

Signature Length Check:
- The module first checks if the provided signature is 65 bytes long, which is the standard length for ECDSA signatures.
Public Key Recovery:
- Using the signature and the transaction ID, the module recovers the public key. This recovery process involves complex cryptographic operations that ensure the public key is correctly derived from the signature.
Address Verification:
- The recovered public key is then converted into an address. The module checks if this address matches the sender's address provided in the transaction. If they match, the signature is considered valid.

This module's primary role is to provide a robust and efficient method for validating the authenticity of transactions in the Veive protocol, ensuring that only authorized transactions are processed.
