# Hardware RNG Implementation Status
|
||||
|
||||
## Overview
|
||||
|
||||
The OTP cipher application now includes comprehensive hardware Random Number Generator (RNG) device support with automatic detection, device identification, and graceful handling of different device types.
|
||||
|
||||
## Supported Devices
|
||||
|
||||
### ✅ Fully Supported (TrueRNG Family)
|
||||
- **TrueRNG Original** (VID: 04d8, PID: f5fe)
|
||||
- **TrueRNG Pro** (VID: 04d8, PID: 0aa0)
|
||||
- **TrueRNG Pro V2** (VID: 04d8, PID: ebb5)
|
||||
|
||||
These devices work via serial port communication and are fully integrated into the entropy collection system.
|
||||
|
||||
### ⚠️ Detected but Not Supported (SwiftRNG Family)
|
||||
- **SwiftRNG** (VID: 1fc9, PID: 8111)
|
||||
|
||||
SwiftRNG devices are detected and identified but cannot be used via serial port communication. They require the official SwiftRNG API with libusb-1.0 integration.
|
||||
|
||||
## Implementation Features
|
||||
|
||||
### Device Detection
|
||||
- **Automatic scanning** of `/dev/ttyUSB*` and `/dev/ttyACM*` devices
|
||||
- **VID/PID identification** via sysfs to distinguish device types
|
||||
- **Multi-device support** with interactive selection menus
|
||||
- **Real-time status indicators** showing device availability
|
||||
|
||||
### Device Communication
|
||||
- **Optimized serial port configuration** for each device type
|
||||
- **Timeout protection** to prevent hanging on unresponsive devices
|
||||
- **Error handling** with clear diagnostic messages
|
||||
- **Progress tracking** with speed estimation for large entropy collections
|
||||
|
||||
### Integration Points
|
||||
- **Pad enhancement** via entropy addition to existing pads
|
||||
- **Interactive menus** for device selection when multiple devices are present
|
||||
- **Command-line support** for automated workflows
|
||||
- **Graceful fallback** to other entropy sources when no hardware RNG is available
|
||||
|
||||
## Technical Implementation
|
||||
|
||||
### Core Functions
|
||||
- `detect_all_hardware_rng_devices()` - Scans and identifies all connected devices
|
||||
- `collect_truerng_entropy_from_device()` - Collects entropy from TrueRNG devices

## Architecture
|
||||
|
||||
The OTP cipher uses a modular architecture with clean separation of concerns:
|
||||
|
||||
- **main.c**: Application entry point, command line parsing, and mode selection
|
||||
- **ui.c**: Interactive user interface, menus, and terminal management
|
||||
- **state.c**: Global state management (pads directory, terminal dimensions, preferences)
|
||||
- **crypto.c**: Core cryptographic operations (XOR encryption, ChaCha20 entropy mixing)
|
||||
- **pads.c**: Pad file management, checksums, and state tracking
|
||||
- **entropy.c**: Entropy collection from keyboard, dice, and other sources
|
||||
- **trng.c**: Hardware RNG device detection and entropy collection from USB devices
|
||||
- **util.c**: Utility functions, file operations, and helper routines
|
||||
|
||||
All modules share a common header (`include/otp.h`) that defines the public API and data structures.
|
||||
|
||||
## Hardware RNG Device Support
|
||||
|
||||
The OTP cipher includes comprehensive support for hardware random number generators (RNGs) to enhance entropy quality for pad generation and entropy addition operations.
|
||||
|
||||
### Supported Devices
|
||||
|
||||
The system automatically detects and supports the following hardware RNG devices:
|
||||
|
||||
| Device | VID:PID | Status | Notes |
|
||||
|--------|---------|--------|-------|
|
||||
| **TrueRNG** | 04d8:f5fe | ✅ Working | Original TrueRNG device |
|
||||
| **TrueRNG (Alt)** | 1fc9:8111 | ✅ Working | Alternative VID/PID combination |
|
||||
| **TrueRNG Pro** | 04d8:f5fe | ✅ Working | Professional version |
|
||||
| **TrueRNG Pro V2** | 04d8:f5fe | ✅ Working | Latest professional version |
|
||||
|
||||
### Device Detection
|
||||
|
||||
The system automatically scans `/dev/ttyACM*` ports and identifies hardware RNG devices by:
|
||||
|
||||
1. **USB VID/PID Detection**: Reading vendor and product IDs from sysfs
|
||||
2. **Device Type Classification**: Identifying specific device variants
|
||||
3. **Port Configuration**: Applying device-specific serial port settings
|
||||
4. **Interactive Selection**: Presenting available devices for user selection
|
||||
|
||||
### Testing Hardware Devices
|
||||
|
||||
A comprehensive test script is included to verify hardware RNG functionality:
|
||||
|
||||
```bash
|
||||
# Run hardware device tests
|
||||
./test.sh
|
||||
```
|
||||
|
||||
The test script performs:
|
||||
- **Device Detection**: Scans for and identifies all connected hardware RNG devices
|
||||
- **Connectivity Testing**: Verifies each device can be opened and read from
|
||||
- **Configuration Testing**: Validates serial port configuration for each device type
|
||||
- **Entropy Quality Analysis**: Measures Shannon entropy of collected random data
|
||||
|
||||
### Current Test Results
|
||||
|
||||
Based on testing with actual hardware devices:
|
||||
|
||||
**✅ Working Devices:**
|
||||
- TrueRNG (Type 1): Full functionality confirmed
|
||||
- TrueRNG Pro V2 (Type 3): Full functionality confirmed
|
||||
|
||||
- Device is detected and identified correctly
|
||||
- Serial port configuration may need adjustment for this device variant
|
||||
|
||||
### Usage in Entropy Collection
|
||||
|
||||
When generating pads or adding entropy, the system will:
|
||||
|
||||
1. **Auto-detect** all connected hardware RNG devices
|
||||
2. **Present a menu** of available devices if multiple are found
|
||||
3. **Test connectivity** before beginning entropy collection
|
||||
4. **Estimate completion time** based on device speed testing
|
||||
5. **Collect entropy** with progress indicators and quality metrics
|
||||
|
||||
### Device Configuration
|
||||
|
||||
Each device type uses optimized serial port settings:
|
||||
|
||||
- **TrueRNG devices**: 3Mbps baud rate, 8N1, no flow control
|
||||
- **Automatic timeout protection**: Prevents hanging on unresponsive devices
|
||||
- **Error recovery**: Graceful handling of device disconnection during operation
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
If hardware RNG devices are not detected:
|
||||
|
||||
1. **Check USB connections**: Ensure devices are properly connected
|
||||
2. **Verify permissions**: User must have access to `/dev/ttyACM*` devices
|
||||
3. **Check device enumeration**: Use `lsusb` to verify USB device recognition
|
||||
4. **Review sysfs entries**: Ensure VID/PID information is available in `/sys/bus/usb/devices/`
