1. A method for standardizing an initial bit flow, which is provided by a first noise source, in an apparatus having a buffer resulting in a standardized bit flow output, the method comprising: dividing the initial bit flow provided by the first noise source into a plurality of bit words of identical lengths and storing at least one bit word in a buffer; generating an output bit stream based at least in part on the input bit flow provided by the first noise source, each bit of the output bit stream corresponding to one bit word of the plurality of bit words; assigning an output state for at least some bits of the output bit stream based on bit states of corresponding bit words stored in the buffer; and inverting the output state according to the occurrence, in the initial bit flow, of at least one bit word having identical bit states so that the output bit stream provides a standardized bit flow.
