ARRANGEMENT AND METHOD FOR CHECKING THE ENTROPY OF A RANDOM NUMBER SEQUENCE

摘要

According to one embodiment, an arrangement for checking the entropy of a random number sequence is described including a random source configured to provide a random input sequence, a post-processing circuit configured to receive the random input sequence and to generate a random number sequence from the random input sequence by performing a post-processing and a decimation of the random input sequence, an inverse post-processing circuit configured to receive the random number sequence from the post-processing circuit and to generate a processed random number sequence by a processing of the random number sequence that is inverse to the post-processing performed by the post-processing circuit, and an entropy checker configured to check the entropy of the random number sequence based on the processed random number sequence.
