RFDom
Hardware random number generator using radio frequency noise from RTL-SDR devices.
Overview
RFDom provides a drop-in replacement for Python's random module that generates cryptographically strong random numbers from atmospheric radio noise. It uses an RTL-SDR device to capture IQ samples, converts them to seeds via phase angle analysis and SHA-256 hashing, and feeds these into an LCG for deterministic random number generation.
Requirements
- RTL-SDR device
- RTL-TCP server running (e.g.,
rtl_tcp -a 0.0.0.0) - Python 3.x
Installation
pip install rfdom
Or from source:
git clone https://github.com/douxxtech/rfdom.git
cd rfdom
pip install -e .
Usage
from rfdom import RFDom
# Connect to RTL-TCP server
rng = RFDom(host="192.168.1.185", gain=49.6)
# Use like Python's random module
print(rng.random()) # 0.0 to 1.0 [0.0, 1.0)
print(rng.randint(1, 100)) # Random integer [1, 100]
print(rng.choice(['a', 'b', 'c'])) # Random choice
print(rng.gauss(0, 1)) # Gaussian distribution
Supported Methods
random(),uniform(),randint(),randrange()choice(),choices(),sample(),shuffle()gauss(),expovariate()
