Re: which security protocol for dealing with this situation

An SSL certificate on the "base" computer's web server would provide

And DynDNS sells them:

The "real" server assumably would be the only one running the web
server with the SSL certificate issued to whatever.dyndns.org

So long as hasty users don't click through any warning boxes about
mismatching certificates, and so long as a certificate authority
trusted by the web browser in question doesn't issue a bad guy a
certificate for someone else' dyndns domain, I think you're where you
wanna be.

Yes that looks like, without entirely knowing/understanding the
details, exactly what I'm after... apart from the $139 per year bit.
Tis a great shame that's necessary. Is there possibly another way that
doesn't require subscription? I suppose the good thing about ssl is
that browsers support it. What if installing custom utility/app on
phone was possible?; What other methods would then be possible? PGP?
Would that be useful? What about what Steve Riley was talking about
above, IPsec?

Bearing in mind the phone and base machine can be synchronised/aligned
with each other securely/safely beforehand, and intermittently during
the course of use, does that allow for some protocol to be used which
doesn't require these third parties possibly?

Thanks.
