I have not yet seen any hints on how a back-channel within the S/MIME
protocol can work. There are claims that this can be done with CRLs and
OCSP but that all requires substantial implementaion bugs in the S/MIME
engines. The paper presents only vague ideas. Did I miss something?
Note that when talking about S/MIME I actually mean the CMS/X.509 part
and not the MIME part of it. For sure the same MIME parser bugs a few
OpenPGP MUAs showed will also work with S/MIME - and even easier due to
the missing intgerity protection at the crypto level.
