As backward compatability is only an issue between versions of S/MIME. Would
a compromise be for CMS to keep to the existing mandatory algorithms as
specified in RFC 2630 (DH/DSA), but in the message specification RFC 2633
also mandate support for RSA, for backward compatinility reasons with S/MIME

I know this means that both sets of algorithms have to be implemented in
S/MIME, but is that really a big problem.

Hi Russ,



As chairman, I am trying to figure out the consensus of the  work
group.  If everyone has enough information from this thread,
then I would
like to hear from folks that have an opinion but have not spoken up yet.

My 2 centavos are: Keep PKCS#1.5 with appropriate notification on
the known
attack(s) and recommended procedures to minimize their effect. As you
stated, there is already reference to OAEP for future versions.
