Re: Cryptology and knot theory?

17.10.3. Ciphers are somewhat like knots...the right sequence of moves unties them, the wrong sequence only makes them more tangled. ("Knot theory" is becoming a hot topic in math and physics (work of Vaughn Jones, string theory, etc.) and I suspect there are some links between knot theory and crypto.)

Has any work been done along those lines?

I did some searches with AltaVista, but I only found Cyphernomicon...

I would have my doubts about how interesting the direction could get, since knot theory is a dead area. The classification problem was fully solved, and after that things got boring... Perry
