  1. Internet2 MiddlewarePKI: Oy-vey! Michael R. Gettes Principal Technologist Georgetown University gettes@Georgetown.EDU http://www.georgetown.edu/giia/internet2

  2. HEPKI • Sponsors: Internet2, EDUCAUSE, CREN • TAG – Technical Activities Group • Jim Jokl, Chair, Virginia • Techonology, practicality, deployment, testbeds • PAG – Policy Activities Group • (Default Chair), Ken Klingenstein, Colorado • Knee-deep in policy(CP), HEBCA, Campus, Subscribers and Relying Party issues. • PKI Labs (AT&T)– Neal McBurnett, Avaya • Wisconsin-Madison & Dartmouth • Industry, Gov., Edu expert guidance • http://www.educause.edu/hepki

  3. HEPKI-TAG Activities • Charter – Technical Activities Group (TAG) • Certificate profiles, CA software • Private key protection • Mobility, client issues • Interactions with directories • Testbed projects (PKI-Lite, S/MIME Interop, Profiles) • Communicate results • http://www.educause.edu/hepki

  4. HEPKI-PAGWe don’t need no stinkin’ policy? • Policy, Lawyers, documenting practice, what gives? • Going outside the institution. Staying inside doesn’t require new policy (rather new practice) • PKI seems to make authN / authZ a legitimate problem deserving legal attention • Working with U.S. Gov’t on PKI Policy • Moved the development of HEBCA Cert Policy • Realized need for Campus Model Cert Policy • Realized need to simplify policy for PKI-Lite

  5. HEBCA: Higher Education Bridge Certificate Authority Michael R Gettes Georgetown University gettes@Georgetown.EDU

  6. Multiple CAs in FBCA Membrane • Survivable PKI • Cross Certificates allow for “one/two-way policy” • Directories are critical in BCA world.

  7. A Snapshot of the U.S. Federal PKI DOD PKI Illinois PKI CANADA PKI Federal Bridge CA NASA PKI Higher Education Bridge CA University PKI NFC PKI

  8. What is Cross Certification? • A Bridge signs a CA and CA signs bridge • Policy OIDs and Name Constraint controls are in the cross certificates • Cross Certificates are published in directories and discovered via the network. BCA/CA may remain off-line. • Policy OIDs could map to XML documents describing the policy (processed per Carmody)

  9. Path Validation • Application receives a Certificate • Finds a path back to signer of Certificate validating the path for policy mappings and name constraints. • Policy Mappings can be LOA (levels of assurance) or “we agree to be in club shib” or whatever • Name Constraints controls subjectName name space. I.E. a CA can only sign within dc=U,dc=edu

  10. On Policy • We have a draft HEBCA Certificate Policy • The HE CP and HEBCA CP are congruent • The HEBCA CP and FBCA CP are congruent • We need a HEPKI PA – EDUCAUSE is working this problem – granted “power” from ACE

  11. NIH- Educause PKI Pilot:Phase Two Electronic Grant Application With Multiple Digital Signatures Peter Alterman, Ph.D. Director of Operations Office of Extramural Research

  12. Project Participants • University of Alabama-Birmingham • University of Wisconsin-Madison • University of California, Office of the President • University of Texas – Houston Health Science • Dartmouth College • Georgetown University – HEBCA proper • National Institutes of Health (NIH) • Mitretek (www.mitretek.org)

  13. The Problem • Picture/s of piles of grant applications • About 20,000 5 ft high standing people of paper. • 1 forest per year for just grant apps. • The Solution: signed, electronic grant application • Of course!

  16. Bridge CA vs. Shibboleth • PKI is hard to deploy to end users • Shib should use BCA aware PKI between servers • Club Shib will then scale using Policies and Relationships established by Bridge CA world • ONE Club Shib managed by policy - globally • Java 1.4 is Bridge aware. Whistler supposed to be.
