# ocelli: Camera-Based TRNG
|
|
|
|
**Ocelli** is a Rust application that generates high-quality entropy using a camera feed. The application supports two entropy generation methods (`get_entropy` and `chop_and_stack`) and optionally applies Van Neumann whitening for enhanced randomness. Generated entropy is saved as a binary file.
|
|
|
|
## Features
|
|
|
|
- **Entropy Methods**:
|
|
- `get_entropy`: Compares pixel values between frames.
|
|
- `chop_and_stack`: Combines and processes pixel data with reversed rows.
|
|
- **Van Neumann Whitening**: Optional, enabled via the `-w` flag.
|
|
- **Shannon Entropy Test**: Ensures the randomness quality of generated entropy.
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
cargo run --release -- <entropy_length_in_bytes> <resolution_width> <resolution_height> [-w]
|
|
```
|
|
|
|
### Example
|
|
|
|
```bash
|
|
cargo run --release -- 1024 640 480 -w
|
|
```
|
|
|
|
This generates 1024 bytes of whitened entropy using a 640x480 resolution.
|
|
|
|
## Requirements
|
|
|
|
- OpenCV 4.x
|
|
|
|
## Installation
|
|
|
|
1. Install Rust: https://www.rust-lang.org/tools/install
|
|
2. Install OpenCV: Follow the [official guide](https://docs.opencv.org/).
|
|
3. Clone the repository:
|
|
```bash
|
|
git clone <repository_url>
|
|
cd ocelli-entropy-generator
|
|
```
|
|
4. Run the application:
|
|
```bash
|
|
cargo run --release -- <arguments>
|
|
```
|
|
|
|
## Output
|
|
|
|
Generated entropy files are saved in the current directory with a name format:
|
|
```
|
|
<method>[_whitened]_YYYYMMDD_HHMMSS.bin
|
|
``` |
