Self-shrinking generator : ウィキペディア英語版 | Self-shrinking generator A self-shrinking generator is a pseudorandom generator that is based on the shrinking generator concept. Variants of the self-shrinking generator based on a linear feedback shift register (LFSR) are studied for use in cryptography. ==Algorithm==
In difference to the shrinking generator, which uses a second feedback shift register to control the output of the first, the self-shrinking generator uses alternating output bits of a single register to control its final output. The procedure for clocking this kind of generator is as follows: # Clock two bits from the LFSR. # If the pair is 10 output a zero. # If the pair is 11 output a one. # Otherwise, output nothing. # Return to step one.
