Abstract

This article describes a method to turn astronomical imaging into a random number generator by using the positions of incident cosmic rays and hot pixels to generate bit streams. We subject the resultant bit streams to a battery of standard benchmark statistical tests for randomness and show that these bitstreams are statistically the same as a perfect random bit stream. Strategies for improving and building upon this method are outlined.
