Noisy Diode entropy source

The Cryptech project is using Avalanche Noise as a physical entropy source connected to the FPGA.

Avalanche breakdown is a physical process that occurs when current is forced backwards through a diode until it cannot hold back anymore. The diode will then begin conducting for a brief time until the …

Randomness Testing Tools

This page explains some basics on testing for randomness, and the background necessary to understand their outputs.

Basic Considerations

When testing the randomness of an alleged/assumed random bit/byte stream, there are two fundamentally different categories of tests: There are blackbox tests which are independent of the particular source …
