Project Overview

This project is a Python implementation of a practical Secure Multi-party Computation (SMPC) scenario, simulating how two millionaires (A and B) can compare their wealth without revealing their exact financial status. We utilize SMPC techniques to ensure data privacy.

File Structure

• utils.py: Contains fundamental utility functions related to RSA encryption, including key generation, encryption, and decryption.
• utils_test.py: Tests the functionality of the tools in the utils file, ensuring that the encryption and decryption processes are working as expected.
• index.py: The core code for simulating the millionaire's problem, demonstrating how a designed secure communication protocol allows both parties to effectively compare their wealth while remaining encrypted.

Running Instructions

First, run utils_test.py to verify the correctness of the encryption utilities.
Then, proceed with running index.py to see the simulated process and the final outcome.
