Process and device for generating unique pseudo-random numbers

摘要

The process consists in registering (1, 2) into a specified area of the non-volatile memory of a microcircuit memory card a specified and non-repetitive value item with each generating of a random number and in converting (3, 4) this item into an item having the form of a pseudo-random number by programming the processing unit by means of a standard information encrypting program of the DES type. Application: memory cards. <IMAGE>
