Zero-Knowledge Proof Authentication System

This project demonstrates a secure authentication system using zero-knowledge proofs implemented through a gRPC-based client-server architecture. The server offers user registration, authentication challenge creation, and verification to ensure privacy and security during authentication.

Project Overview

The project consists of two main components: the server and the client.

Server

The server provides the authentication service through gRPC, offering the following functionalities:

• User registration with unique usernames and passwords 'x'.
• Creation of authentication challenges with random 'c' values for users.
• Verification of authentication responses.

Client

The client interacts with the server to facilitate user registration and authentication:

• Users can register with unique usernames and passwords 'x'.
• Users can log in by responding to authentication challenges using calculated responses 's'.

Getting Started

Follow these steps to set up and run the server and client components of the project.

Prerequisites

• Python 3.6 or higher
• gRPC (Python library)

Installation

1. Clone the repository:

   git clone https://github.com/ayushguptacse14/ZKP-Auth-Protocol.git
   cd ZKP-Auth-Protocol

2. Install gRPC (if not already installed):

   pip install grpcio grpcio-tools

Running the Server

1. Run the server:

   python server.py

   Or

2. Run docker container

   docker-compose up --build

Running the Client

1. Open a new terminal window.

2. Run the client script:

   python client.py

Running Tests

Unit tests are provided in the test.py file. To run the tests, follow these steps:

1. Open a terminal window.

2. Navigate to the project root directory:

   python server_test.py
   python client_test.py

Usage

1. Register: Choose option 1, enter a username and password 'x', and the user will be registered.
2. Login: Choose option 2, enter the registered username and the corresponding password 'x', and the user's authentication status will be displayed.
3. Exit: Choose option 3 to exit the client.
