Like you mentioned, so-called "pseudorandom" number sequences are also identical for the same initial seed. I felt that "somewhat random" was less strong of a statement than "pseudorandom", but I can see where others would disagree. So I probably should have just stuck with "pseudorandom".

For what it's worth, I find "disordered" and "lacking pattern" worse (the bits have a definite pattern and order). ;)

This reminds me that I forgot to mention that the bit stream from a single LFSR has been studied to the point that a small subseries of bits is enough to predict the entire series. However, two carefully chosen LFSRs where each bit from one is used to determine whether the next bit from the other will be output or thrown away has been analyzed and found to be cryptographically strong.

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



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
