Abstract
The present invention provides a method of generating a sequence of pseudo-random numbers which are difficult to predict. The method includes: (i) generating a plurality of candidate pseudo-random numbers by a respectively corresponding plurality of (differently structured) linear feedback shift registers; (ii) generating a 'selector number' from one or more additional linear feedback shift registers; and (iii) selecting a candidate number from the plurality of candidate numbers, based on the 'selection number' to produce a selected pseudo-random number for output.
