RANDOM NUMBER GENERATOR USING COMPRESSION

摘要

This invention relates to a random number generator that receives a number of input bits based on at least one random or pseudo-random source. The bits are compressed according to a compression scheme like Ziv-Lempel in order to enhance the entropy and randomness of the random source(s). Additionally, any eventual problem regarding drifting statistical characteristics, e.g. due to temperature change, aging of components, etc. is minimised/eliminated. In this way a random number generator is provided that generates high quality random numbers securely and efficiently. This invention also relates to a corresponding method for generating at least one random number based on a hardware source/unit.
