  • Pseudo-random number generation method and pseudo-random number generator
    Publication number: 20060039558
    Abstract: A bit string obtained by sampling, every the number s, bits of a bit string whose output sequence is M sequence, when the bit number per one cycle of the M sequence is prime to the derived value, constitutes M sequence of a linear feedback shift register having other construction. Further, the linear feedback shift register can be determined from bits corresponding to at least two cycles by Berlekamp-Massay algorithm, whereby the linear feedback shift register 11 can be easily and dynamically reconstructed based on the initial state value.
