Abstract
An integrated circuit card includes a microprocessor, an integral memory element, and a pseudo-random number sequence file stored therein. The pseudo-random number sequence file includes a pseudo-random number sequence generator operable to generate an instance of a sequence of apparently random numbers when executed, values for the parameters of the pseudo-random number sequence generator, and an Initial Value for the sequence of random numbers. The microprocessor is operable to execute an operation on the pseudo-random number sequence file in response to a predetermined input from an external source.
