<P>PROBLEM TO BE SOLVED: To provide a random number sequence generation device by which a generated random number sequence has favorable natures as the random number sequence, and to provide a random number sequence generation method, and a program for materializing the device and the method by means of a computer. <P>SOLUTION: The pilot reception section 102 of the random number sequence generation device 101 receives the integer string of w bits as a pilot. An initialization section 103 provides the integer string of the received pilot to a conversion section 104. The conversion section 104 applies conversion defined by nonlinear conversion g to the respective provided integer strings to obtain the integer string of the w bits. A rotation section 105 conducts the specified rotation operation by understanding the obtained integer string as the bit string of wn bits to obtain the integer string of the w bits from the obtained bit string of the wn bits. An output section 107 determines that whether or not conversion in the conversion section 104 and rotation in the rotation section 105 are repeated by the specified number of times, and finally, outputs the integer string obtained from the rotation section 105 as the random number sequence. A renewal section 106 provides the integer string obtained from the rotation section 105 to the conversion section 104 to repeat processing. <P>COPYRIGHT: (C)2004,JPO |
