Quantum-Secure is an educational and research-oriented GUI tool that simulates hybrid quantum-classical secure communication using an extended BB84 protocol. It incorporates post-quantum authentication (Falcon-style), eavesdropping simulation, real-time QBER/entropy visualization, and secure messaging tailored for smart grid nodes.
- Extended BB84 Protocol: Implements a visualized and secure key distribution using quantum bits with classical fallback.
- Simulated MITM/Eavesdropping Attacks: Demonstrates practical QKD vulnerabilities and countermeasures.
- Post-Quantum Authentication: Employs Falcon-style signature simulation for secure authentication.
- Hybrid Key Agreement: Combines quantum keys with classical X25519 Diffie-Hellman keys.
- ChaCha20-Poly1305 Encryption: Used for secure messaging between nodes after key exchange.
- Smart Grid Nodes Simulation: Includes various node types like control centers, meters, and sensors.
- Live Visualization & Metrics: Real-time graphs for QBER, entropy progression, and protocol performance.
- MITM Detection Metrics: Entropy saturation analysis and eavesdrop-error overlap detection.
- GUI Built with Tkinter + Matplotlib: Optimized for Windows and cross-platform support.
- Python 3.8+
- Qiskit
- NumPy
- Matplotlib
- SciPy
- Cryptography
- tkinter (included with standard Python installations)
