Abstract:
1. An integrated circuit card, comprising: a microprocessor; a memory system integral with said microprocessor; and one or more pseudo-random number sequence files stored in said integral memory system, said one or more pseudo-random number sequence files including a pseudo-random number sequence algorithm code operative to generate a current instance of a pseudo-random number sequence when executed; a parametric data set for said pseudo-random number algorithm code wherein said parametric data set includes values for parameters of said pseudo-random number algorithm code; and a current state data set for said pseudo-random number algorithm code, for storing information associated with said one or more pseudo-random number algorithm codes, said current state data set including at least an Initial Value defining an initial state value for the pseudo-random number sequence; wherein said microprocessor is operative to execute an operation on one of said pseudo-random number sequence files in response to a predetermined input; and wherein said information stored in said current state data set comprises a Current Index having a value that identifies each current instance of the pseudo-random number sequence generated by said pseudo-random number algorithm code and a Current Value having a value equal to the current instance of the pseudo-random number sequence generated by said pseudo-random number algorithm code.
