Use your phone's camera as a high volume thermal entropy generator - creates genuine random numbers at a rate of over 18 Mb/min.

How it works

TrueEntropy uses your phone's camera to generate true random numbers derived from thermal noise. The camera in your smartphone is so advanced that it can detect even the smallest variations produced by fundamental particle physics. We capture thermal variations in every pixel of your phone's camera to create a powerful, high volume entropy random number generator. No need to move your phone! Leave your phone stationary, and TrueEntropy will pick up a sufficient quantity of thermal variations to generate random numbers at a rate of 18Mb per minute.

  • Generate binary files for local use via AirDrop
  • Send entropy to a destination machine via cryptographic relays
  • Continuous generation mode to constantly reseed target machines

Features

  • Delivering entropy via AirDrop or via network (Zax relay)
  • Works on iPhone and iPad
  • Configurable block size and amount
  • Option to decline blocks with low χ²
  • Option to generate CSV file for manual testing

Requirements

iOS 9.3 and Swift 4.0 are required.

Installation

App depencies have to be install using CocoaPods, which is a dependency manager for Cocoa projects. To install it, run:

$ gem install cocoapods

Then, run the following command:

$ pod install

Then open TrueEntropy.xcworkspace file.

Configuration

You can edit particular predefined constants (like camera resolution, range of acceptable sample mean etc) in Constants.swift.
