Abstract

A secure number generator (10, SNG 1... 10) is disclosed, comprising a random function unit (12) and a non-volatile memory (18, 20) connected to said random function unit. The random function unit (12) implements an unstable, measurable random quantity (14), such that a repeated measurement of the random quantity results in different random values. The random function unit (12) is adapted to ascertain a current random value of the random quantity (14), to transform the current random value into a digital random code, and to write said digital random code to a first section (18) of said non-volatile memory. Further, a content distribution network employing the secure number generator is disclosed.
