## 🎯 **What is UPAS?**

UPAS (Universal Protocol Analysis & Simulation) is a production-ready framework for **protocol reverse engineering**, **network service emulation**, and **advanced protocol testing**. Originally designed for industrial protocol analysis, UPAS enables security researchers, network engineers, and developers to:

- 🔍 **Reverse engineer** complex network protocols with dynamic pattern matching
- 🎭 **Emulate sophisticated network services** with multi-packet response capabilities
- 🏭 **Simulate industrial protocols** (Modbus, CAN, custom IoT systems)
- 🛡️ **Test security vulnerabilities** in network stacks and devices
- 📡 **Develop protocol analyzers** with real-time variable extraction
- 🎪 **Create behavior simulations** with intelligent state management

---

## ✨ **Key Features**

### 🎯 **Advanced Pattern Matching**

- **Dynamic variable capture**: Extract values with `[CAPTURE:VAR:size]`
- **Wildcard operations**: Skip content with `[SKIP:n]` and `[WILDCARD:n]`
- **Binary pattern support**: Hex patterns with mixed static/dynamic content
- **Real-time analysis**: Immediate pattern matching during packet processing

### 🚀 **Multi-Packet Response System**

- **Sequential responses**: Ordered packets with ACK validation and retry logic
- **Burst responses**: Parallel transmission for complex protocols
- **Delayed sequences**: Custom timing control for realistic simulation
- **Response strategies**: Single, sequence, burst, and delayed modes

### 🔄 **Intelligent State Management**

- **Behavior-driven transitions**: State changes triggered by execution success
- **State-only behaviors**: Transitions without packets (timeouts, delays)
- **Conditional filtering**: Behaviors active only in specific protocol phases
- **Entry/exit actions**: Automatic behavior execution on state changes

### 🌐 **Service-Aware Transport**

- **Automatic routing**: TCP/UDP service selection via transport layer
- **Multi-service support**: UDP unicast/multicast, TCP client/server
- **Advanced socket management**: Robust connection handling with fallbacks
- **Interface control**: Multi-homed systems with interface binding

---

## 🚀 **Quick Start**

## 🐍 **Programmatic API**

UPAS provides a powerful Python API for integrating protocol simulation into your applications.

### Basic Usage

```python
import asyncio
import upas

async def main():
    # Run protocol for 30 seconds
    manager = await upas.run_protocol('protocol.json', duration=30)

    # Check current state
    print(f"Current state: {manager.get_current_state()}")

    # Get protocol variables
    variables = manager.get_variables()
    print(f"Variables: {variables}")

asyncio.run(main())
```

### Advanced Protocol Control

```python
import upas

async def advanced_example():
    # Create protocol manager
    manager = upas.ProtocolManager('protocol.json')

    # Register state change callbacks
    def on_connected():
        print("Protocol connected! Switching to monitoring mode...")
        manager.set_variable("MODE", "MONITORING")

    manager.on_state_change("CONNECTED", on_connected)

    # Start protocol
    await manager.start_async(duration=60)

    # Dynamic state transition
    success = manager.transition_to_state("AUTHENTICATED")
    if success:
        print("Successfully transitioned to AUTHENTICATED state")

    # Stop when done
    manager.stop()
```

### Dynamic Protocol Switching

```python
import upas

async def protocol_switching():
    # Start with discovery protocol
    manager = await upas.run_protocol('discovery.json')

    # Register protocol change callback
    def on_protocol_change(new_protocol):
        print(f"Switched to: {new_protocol['protocol']['name']}")

    manager.on_protocol_change("switch", on_protocol_change)

    # Wait for discovery completion
    await asyncio.sleep(10)

    # Switch to operational protocol
    await upas.change_protocol(manager, 'operational.json')

    # Continue with new protocol
    await asyncio.sleep(30)
    manager.stop()
```

### Engine-Level Control

```python
import upas

async def engine_control():
    # Create and configure engine directly
    engine = await upas.create_engine('protocol.json')

    # Start engine
    await engine.start()

    # Monitor execution
    while engine.is_running():
        stats = engine.get_statistics()
        print(f"State: {stats['current_state']}, Behaviors: {stats['behaviors']}")
        await asyncio.sleep(1)

    # Stop engine
    await engine.stop()
```
