Subject: Re: [pki-tc] PKI TC - Deliverables

I think it would be very valuable and educating if a PKI community like the PKI-TC shed
some light on how *they* believe some of the most common processes you can think of,
like e-procurement, could or should be "cast" in PKI.

Since such processes involve multiple individuals as well as at least two organizations,
you actually run into most issues of interest such as:  authorization, audit, privacy,
identity, encryption, signatures etc etc.

It is important to note that nobody has done this before so such a task is also likely
to face the usual problems pioneers' often do.

The listed stuff below to me rather represent "success stories" rather than guidelines.
The OCSP question we discussed recently is an example of where an in fact extremely
simple question, did not had an obvious answer.  BTW, I still wonder if there was
something missing from my suggestion.

Personally I think that login and e-mail are actually very awkward
applications of PKI and do not represent best practice.  

There are many many other live applications that do represent best practice: 

- Austria's system for lodging all company registrations online with
digital signatures (2.5M Secure Signature Creation Devices in regular use) 
- USPTO online patent lodgement (a few thousand I think) 
- Pan Asia Alliance cross border trade documentation (200,000 active certs) 
- Australian Tax Office business tax returns (100,000) 
- Australian Health eSignature Authority (soon to expand rapidly into
PKI-enabled smartcards for healthcare professionals) 
- Electronic Conveyancing Victoria (in advanced planning stage)
- Taiwanese Playsafe gaming card (10,000 pilot, planned to expand to 5M) 
- Visa/Mastercard 3D Secure (numbers?) 
- Open Cable embedded certs in set-top boxes (millions?) 
- Electronic Certificate of Origin (ECO) projects in Japan, Korea, Sing 
- US FIPS-201 PIV card (PKI applications yet to be announced as far as I
know BUT NIST has stated that PKI is essential to resist Man In The Middle
attack, so one presumes that a whole raft of applications will soon be
built around the powerful embedded multi-certificate capability of the

Whether or not these applications have been documented to Anders'
satisfaction is another question.  

A minimalist approach would be to write these up as case studies (and
indeed, the Asia PKI Forum has asked the PKI TC to contribute to its Case
Book, which has been posted to the Members Website already). 

A slightly greater effort could be put into abstracting what it is about
these applications that make them ammenable to PKI, and then we could write
up a guideline or a manual to guide application selection and certificate
