Nope. SHTTP is the Shiffman et. al. protocol.
HTTP over SSL is https:...
I don't have exact citations, nor do I have time to look
them up.
If anybody else does, I'm interested: I maintain:

Yes, due to the possibility of man-in-the-middle attacks,
"bootstrapping" security is quite difficult: you can't just
take cleartext declarations of the form "printer X does/does not
support security mechanism Y" and act on them. You have to
have some way of authenticating even that first step.
So you really need a protocol with message integrity before
you can even start negotiating.
You could get security declarations (and key/certificate material)
out of authenticated
body parts (e.g. HTML docs) sent over HTTP using MD5-auth or
some such. Hmmm...
