Discussion
Revised Profiles for PKI-Lite
The revised version of
the PKI-Lite profile posted
to the web site includes
requiring basic constraints
to be critical. A new section
was added for the identifier
for subject alt name in
the identity certificate.
Several different software
vendors, Microsoft, Cisco
ACS, and Funk handle it
this way. It's not clear
if all types of software
would back off the same
way to presuming there is
a unique subject name. A
sentence will be added to
that effect. The updated
root certificate is identical
to the previous one except
it requires basic constraints
to be marked critical. The
group accepted the changes.
InCommon end-entity profile
Eric pointed out and Jeff concurred that MIME type under authority information access is incorrect. Jim believed that it was tested and worked for Microsoft. He was not sure if it was required or simply the default.
Shelley e-mailed the list
regarding questions from
her sysadmins on PGP vs.
S/MIME, which is preferable
and why. In general it's
not a one is better than
the other, but which is
better for a given situation.
For a campus full of people
S/MIME scales better, for
a small group PGP works
well. When deploying certificates
on a campus it's usually
done in the context of a
variety of applications,
of which S/MIME is just
one application. There was
general consensus that it
would be useful to put together
information about PGP vs.
S/MIME, and PGP deployment
for the HEPKI-TAG web site.
Shelly indicated they have
a PGP web at USC to send
CSR's via e-mail. They are
working on a web application
to accept CSR's in an authenticated
fashion with PGP.
Jeff has a PGP key signer
based on Kerberos authentication.
Neal has received a request from the Jabber Software Foundation (JSF) for a signing certificate from USHER. The I2IM group is working with instant messaging and there is interest in using certificates to authenticate, especially for server-to-server authentication for the federation XMPP servers that would want to trust among themselves. This would be similar to the piloting of certs that is done with Shibboleth via InQueue. A Jabber pilot could use the same set of CA's that is used for InQueue. The general feeling was that it would be preferable to gain experience with a number of more typical cases with USHER first.
Steve Hanna is looking for help with respect to the OASIS PKI Technical Committee (PKI TC) Action Plan. It was agreed that people needed time to review the action plan before committing to take on work relating to it.
Bob Morgan attended a Mellon
foundation retreat to discuss
opportunities and overlaps
between projects, including
new applications that imply
somewhat different models
of security. Dartmouth has
submitted a proposal to
use PKI in some form of
capitalization in Chandler
and Lionshare.
Action Items
1. [AI] Jim: Will draft
a paragraph outlining that
for the http URL we expect
it to be pointing at a PKCS7
that will operate with Windows.
2. [AI] All: Please send
Jim signed messages so he
can get the certs up on
the PKIdev repository for
downloading.
3. [AI] Jim will send e-mail
to the list of what certs
are available on PKIdev.
Sorry the action item got
omitted:
4. [AI] All: S/MIME: please
send signed messages from
different clients to the
list so we can fill out
the table on the S/MIME
client data. Barry will
arrange for a new Apple
client signed message sent
to be sent to the list.
Eric will send an S/MIME
signed message from Pine
to the list.
5. [AI] Bob will forward
the link to Chandler and
the Dartmouth PKI proposal
sent to Chandler.
6. [AI] Neal: Will contact
Peter St. Andre about participating
in the next HEPKI-TAG call.
7. [AI] Jeff will send the
PGP key signer to Shelly
for review.
8. Shelly indicated that
they have some USC specific
documentation on PGP deployment
at www.usc.edu/authx.
9. [AI] Shelly will oversee
the development of a PGP
deployment guide for the
HEPKI-TAG site
10. [AI] Neal will invite
Steve Hanna to the next
HEPKI call.
