Abstract

See full text

Device for generating random numbers having a pseudo random number generator, a memory and a sequential controller. The pseudo random number generator generates a deterministic random number sequence after an initialization using an initialization value. The memory stores initialization information, wherein the initialization information is derived from a true random number or corresponds to the true random number. The sequential controller initializes the pseudo random number generator at start-up using the initialization information or the information derived from the initialization information, stores an intermediate state of the pseudo random number generator or information derived from the intermediate state in the memory at a turn-off of the pseudo random number generator, and uses the intermediate state or the information derived from the intermediate state for an initialization of the pseudo random number generator at a renewed start-up.
