QuantumShield-LWE-Cryptography

A Research-Stage Implementation of a Multi-Block LWE Cryptosystem with Basic Error Correction

🚧 Project Status: Experimental Prototype

This repository contains a proof-of-concept, educational implementation of a lattice-based cryptographic scheme built on the Learning With Errors (LWE) problem enhanced with a basic Hamming (7,4) error correction code.

⚠️ Important Notices

  • Not production-ready: This project is not a secure, reliable cryptosystem suitable for real-world use.
  • High error rate: The current implementation exhibits significant decoding errors due to the limited error correction capability of Hamming (7,4).
  • For research and learning purposes only: Designed primarily for academic exploration and demonstrating integration of error correction with LWE cryptography.
  • Expect ongoing breaking changes: Algorithmic improvements, parameter tuning, and bug fixes will continue as this is a work-in-progress.

📋 Features

  • Multi-block LWE key generation, encryption, and decryption.
  • Integration with Hamming (7,4) error correction for single-bit error correction per block.
  • Modular design with clearly separated components for LWE operations and error correction.
  • Basic unit tests and example scripts for demonstration.
