Random number generator for cryptographic applications e.g. for chip card, has intermediate condition of pseudo-random number generator stored in memory as initializing information

摘要

The random number generator has a pseudo-random number generator (1000) for provision of a deterministic random number sequence after initializing with an initialization value, a memory (1400) holding initializing information obtained from a genuine random number and a sequence control (1600) initiating the initializing of the pseudo-random number generator using the stored information when the pseudo-random number generator is brought into operation and storage of an intermediate condition of the pseudo-random number generator when the latter is switched out of operation. Also included are Independent claims for the following: a method for generation of random numbers using a pseudo-random number generator; a manufacturing method for a random number generator; a method for personalizing a random-number generator; a computer program for generation of random numbers, manufacture of a random number generator or personalizing a random number generator.
