PROBLEM TO BE SOLVED: To generate a random number sequence which is sufficiently random with buffer capacity and arithmetic of about 16-64 KB in random number generation algorithm.;SOLUTION: A method for random number scrambling in stream cipher include: (1) an initial value generating step for inserting a first random number sequence in the first column of each row of a two dimensional matrix table; (2) a two dimensional random number matrix setting step for inserting a second random number sequence having the first column of each row as an initial value; (3) a random number extracting step for extracting a first numeric value from the two dimensional matrix table; (4) an address generating step for generating the address of a second numeric value to be extracted next from the first numeric value; and (5) a step for inserting a new random number into the place from which the first numeric value is extracted. And the program is provided.;COPYRIGHT: (C)2006,JPO&NCIPI
