1. A method for post-processing an output of a random source of a random generator, the random source outputting a digital output signal having a bit width of at least one bit, comprising:
- compressing, via a circuit, the output signal; and
performing a blockwise linear logical combination of n successive bits of the output signal in a context of the compression, wherein n is a compression factor, with a result that a compressed output signal is generated that encompasses a sequence of compressed signal values,checking, via a checking device, the sequence of compressed signal values by a distribution test in terms of a distribution of the sequence.

Abstract
A method and an assemblage for post-processing an output of a random source of a random generator are presented. In the method, an output signal of the random source is compressed, thereby yielding a sequence of compressed signal values that are checked in terms of their distribution.

10. An assemblage for post-processing an output of a random source of a random generator that outputs a digital output signal having a bit width of at least one bit, the assemblage comprising:
-
a circuit configured to compress the output signal, a blockwise linear logical combination of n successive bits of the output signal being performed in a context of the compression, n being a compression factor, with a result that a compressed output signal is generated which encompasses a sequence of compressed signal values; and a checking device with which the sequence of compressed signal values is checked in terms of a distribution of the sequence.
