### 🔒 Overview
**IoTPatch** is a Python-based **secure IoT firmware patching framework** designed to demonstrate **encrypted update delivery** and **authenticated device connectivity** over **MQTT with TLS**.
It provides a modular interface to:
- ✅ Establish **secure MQTT communication** between IoT nodes and servers.
- 🔐 Manage **firmware updates and patches** safely using certificate-based authentication.
- ⚙️ Integrate lightweight security layers for **IoT edge devices** with minimal dependencies.
Ideal for **IoT security researchers, embedded developers, and students** exploring **secure OTA (Over-The-Air)** update mechanisms.

## 🏗️ Architecture
```text
+---------------------------+ MQTT/TLS +---------------------------+
| IoT Device | <-------------------------> | IoT Patch Server |
|---------------------------| |---------------------------|
| • iotpatch.net (Client) | | • Patch Distribution Node |
| • Patch Manager | | • Validation Engine |
| • Crypto & Utils | | • Certificate Authority |
| • Auto-apply + Rollback | | • Update Scheduler |
+---------------------------+ +---------------------------+

[Secure Patch Pull] [Encrypted Push + Verify]
```
## 🚀 Installation
You can install **IoTPatch** directly from [PyPI](https://pypi.org/project/iotpatch/):
```bash
pip install iotpatch
```
## 🔬 Use Cases
- **Securely updating fleets of smart sensors**
- **Delivering emergency patches to medical IoT devices**
- **Teaching secure OTA in IoT security courses**
- **Prototyping post-quantum-ready update systems**
---
## 📈 Roadmap
- [ ] Web dashboard for patch management
- [ ] Post-quantum signatures (Dilithium)
- [ ] Binary diff optimization (zstd + courgette)
- [ ] Dockerized server with REST API
- [ ] MicroPython port for ultra-low footprint
