Re: A New Triple-DES Key Wrap Algorithm

Apologies if I've missed the point here but...

Is there some specific need to use the same KEK for mailing lists
multiple times or could the same solution be used as in S-S DH? 

In other words make the use of a "salt" in the message compulsory and
use the mailing list key in place of the DH shared secret (ZZ). This
would then allow the same mailing list key to be used multiple times
because the KEK would be different with each salt.
