The Collector — Gigabit True Random Number Generator Using Image Sensor Noise

Abstract

We describe a massively parallel, high per- formance and inexpensive method of capturing physical entropy from existing commodity CMOS imaging sensors. The covers the physics, how to measure its Shannon entropy [1], a simple high performance method to extract this entropy into cryptographic quality random numbers and finally the results of testing against the DieHarder [2] tests.

The result is a recipe on how to create a True Random Number Generator (TRNG) using sensor noise that has a known amount of entropy and how to make sure that the TRNG is functioning properly.
