I wasn't saying that DES was the fastest of all possible secure
ciphers.  I was saying that DES is the fastest of all ciphers which
are widely believed to be secure.  This aspect of security is
moderated by the key length of DES, which is too short to be secure
against a well-funded opponent at present, but which is perfectly
adequate for other purposes.
