Abstract

The invention relates to a method and an apparatus for designing a circuit suitable for generating random bits and to a circuit for generating random bits. A random bit string which is used as a binary random number is generated, for example. The proposed method and the apparatus as well as the circuit are used to implement random number generators, for example. A jth specific function from a set of bijective mappings is selected as the jth function, wherein the jth specific function carries out a jth fixed-point-free mapping. At least one ith mapping device is then selected. An ith specific function from a set of bijective mappings is assigned to the ith function, with the result that an ith concatenation of the i functions carries out an ith fixed-point-free mapping.
