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 …
One, if not THE key functionality in the Cryptech system is the True Random Number Generator (TRNG). We therefore need to discuss, investigate and test to find a TRNG that we and the users of Cryptech can trust and can verify to be trusted.
This page explains some basics on testing for randomness, and the background necessary to understand their outputs.
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 …
