There have been various claims about the (in)security of DES, with the
claim of possible key clustering being one of the most severe.  Has
anyone done any work with other Feistel ciphers (different P & S
boxes, different key schedules or key lengths, etc.)?  In particular,
does IBM (or Feistel himself) have any patents on this ciphering
scheme in general?

Thanks,
