Re: A $25,000,000,000 PKI Was:Spec. on QC-low-fat & QC-heavy-bio



Is this a battle between two Swedes only? Come on guys!

Stefan, my original spec on the low-fat/heavy-bio, did never got a reaction.

Agreed, except that I don't see why such a right should/must be exclusive.

You are almost right.  Security-critical sw developed by several different 
companies requires signed code that you must trust.  This complicates
things considerably.  My approach does probably (not 100% sure here since
CyberPhone is currently only a glossy broschyre) NOT require download
of security-code from independent sources as it is a "Generic Security Platform".

>This does not require the private keys to be used within a server.

This is definitely another question and I would say (while taking on my
marketing hat) that CyberPhone is a "thin PKI" (new sexy term born
this very second) solution that could solve even harder problems than the
"thin client" did.

They don't.  Only in the case they belong to a server-based resource like
a SET account, OBI purchaser

Hum, another IETF-Swede said in another mailing-list that the need for a static
indentity (like an SSN) in a cert is not at all required to maintain a long-lasting
certificate-based relationship in a convenient way.  I asked him if for a
high-level spec. on how he thought that that would work.  He never did it.  I
feel the same thing for your suggestion.  How?  Please...

If you take my "Dynamic Certificates" paper and try to cast that
into conventional PKI you will end up in misery.  Misery = twice the cost,
twice the PITA. and a big chance to be bypassed by other solutions.
