Then I suppose you consider FEAL-4 not to be DED? I would bet a lot
of
money that I could build a strong cipher out of FEAL-4, by just
repeating the
whole encryption enough times with independent keys. If I recall
correctly,
32 rounds of FEAL resist both differential and linear attacks.
Sorry, but single-DES should not be used in any application requiring
serious
security anymore. And it shouldn't have been being used in any such
application
for many years, now. 3DES and DESX are still secure enough for
nearly any
application, as are various other constructions using DES as
components such
as DEAL, some of Terry Ritter's constructions, and (I think) Akalare.
