Abstract

A method to generate a random number from certain input wherein at least parts of the input are modified by data that are independent of the generation of the random number and of the data included in the generation of the random number and a circuit configuration having a processing unit containing an encryption algorithm and a memory into which input is filed. Upon demand for a random number, the processing unit generates a random number using an encryption algorithm and input present in the memory, the current input then being changed by added data.
