Electronic Voting Machine using Homomorphic Encryption

A secure electronic voting system implemented using Django and Paillier Homomorphic Encryption. This system allows for secure vote casting and counting while maintaining voter privacy through advanced cryptographic techniques.

Features

• Secure voter registration and authentication
• End-to-end encrypted voting process
• Homomorphic vote tallying (count votes without decrypting individual ballots)
• Vote verification system
• Admin dashboard for election management

Technology Stack

• Python 3.x
• Django 4.2
• Paillier Homomorphic Encryption (lightphe 0.0.8)
• SQLite (default Django database)

Prerequisites

• Python 3.x installed
• Basic understanding of command line operations
• pip (Python package manager)

Installation and Setup

1. Clone the repository

git clone <repository-url>
cd <repository-name>

2. Create and activate a virtual environment

On Windows

python -m venv venv
venv\Scripts\activate

On Mac/Linux

python3 -m venv venv
source venv/bin/activate

3. Install the required dependencies

pip install -r requirements.txt

4. Run database migrations

python manage.py migrate

5. Run the development server

python manage.py runserver

6. Access the application at http://127.0.0.1:8000/ or http://localhost:8000/

How It Works

This electronic voting system uses Paillier Homomorphic Encryption to ensure:

1. Vote Privacy: Individual votes are encrypted and cannot be traced back to voters
2. Vote Integrity: Votes cannot be altered once cast
3. Verifiable Counting: Vote tallying can be verified without compromising privacy

The Paillier cryptosystem allows for mathematical operations on encrypted values, enabling vote counting without decrypting individual votes.

Security Features

• Homomorphic encryption for vote privacy
• Secure user authentication
• Encrypted data transmission
• Protection against double voting
• Audit trail for verification
