Abstract
Aspects of the present disclosure relate to an apparatus comprising analogue circuitry comprising an entropy source, the entropy source being configured to provide a random output. The apparatus comprises first digital circuitry to receive the output of the entropy source and, based on said output, generate random numbers, and second digital circuitry to receive the output of the entropy source and, based on said output, generate random numbers, the second digital circuitry being a duplicate of the first digital circuitry. The apparatus comprises difference detection circuitry to determine a difference of operation between the first digital circuitry and the second digital circuitry. Each of the first digital circuitry and the second digital circuitry comprises entropy checking circuitry to check the entropy of the output of the entropy source.
