LFSRs CAN be used to encrypt sequences of bits - this is the basic algorithm used to generate CRCs (well nowadays, they are now often generated by looking up data in tables, data generated by the LFSR). When used to generate a sequence of pseudo random numbers, the state of the LFSR is based on the initial seed. The LSB of the next state is based on the XOR of data from all of the taps. When used to encode a bit sequence, the next bit of the sequence is also XOR'ed with the tap data to generate the LSB.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
