  1. PKI Update

  2. Topics • Background: Why/Why Not, The Four Planes of PKI, Activities in Other Communities • Technical activities update • S/MIME Pilot prospects – light CP/CPS • KX.509 and Grid issues • Policy activities: draft HE cert policy, FERPA • European activity • HE Bridge CA, NIH pilot • CREN CA

  3. Why PKI? The Four Stages of PKI Other sectors Federal Activities - fBCA, NIH Pilot, ACES, other Healthcare- HIPAA Corporate Deployments European activities The Industry Higher Ed TAG, PAG Topics

  4. Single infrastructure to provide all security services Established technology standards, though little operational experience Elegant technical underpinnings Serves dozens of purposes - authentication, authorization, object encryption, digital signatures, communications channel encryption Low cost in mass numbers Why PKI?

  5. High legal barriers Lack of mobility support Challenging user interfaces, especially with regard to privacy and scaling Persistent technical incompatibilities Overall complexity Why Not PKI?

  6. D. Wasley’s PKI Puzzle

  7. on the road to general purpose interrealm PKI the planes represent different levels of simplification from the dream of a full interrealm, intercommunity multipurpose PKI simplifications in policies, technologies, applications, scope each plane provides experience and value The Four Planes of PKI

  8. Full interrealm PKI - (Boeing 777) - multipurpose, spanning broad and multiple communities, bridges to unite hierarchies, unfathomed directory issues Simple interrealm PKI - (Regional jets) - multipurpose within a community, operating under standard policies and structured hierarchical directory services PKI-light - (Corporate jets) - containing all the key components of a PKI, but many in simplified form; may be for a limited set of applications; can be extended within selected communities PKI-ultralight (Ultralights) - easiest to construct and useful conveyance; ignores parts of PKI and not for use external to the institution; learn how to fly, but not a plane... The Four Planes are

  9. Spectrum of Assurance Levels Signature Algorithms Permitted Range of Applications Enabled Revocation Requirements and Approaches Subject Naming Requirements Treatment of Mobility ... Examples of Areas of Simplification

  10. CP: Wasley, etal. Draft HE CP stubbed to basic/rudimentary CRL: ? Applications: (Signed email) Mobility: Password enabled Signing: md5RSA Thumbprint: sha1 Naming: dc Directory Services needed: Inetorgperson PKI-Light example

  11. CP: none CRL: limit lifetime Applications: VPN, Internal web authentication Mobility: not specified Signing: not specified Thumbprint: sha1 Naming: not specified Directory Services needed: none PKI-Ultralight

  12. fBCA NIH Pilot ACES fPKI TWG Others – federal S/MIME work Internet2/NIH/NIST research conference ... Federal Activities

  13. HIPAA - Privacy specs issued HIPAA - Security specs not yet done Two year compliance phase-ins Little progress in community trust agreements Non-PKI HIPPA Compliance Options Healthcare

  14. Success stories within many individual corporations for VPN, authentication No current community ABA guidelines Others... Corporate deployments

  15. Generally a bit more successful; can leverage culture, national licensing structures, passports, etc. Higher ed efforts somewhat tied to national efforts; no trans-Euro work of note. http://www.terena.nl/projects/pki/pki-coord011126minutes-draft.html Have major Grid needs coming in 2005 As always, the directories are hard and ad hoc European Efforts

  16. The Industry • What's the problem with PKI then? It all boils down to one thing: Complexity. • Wanted: PKI ExpertsBy Scot Petersen • July 18, 2001

  17. The Industry • Baltimore in peril • PKIforum slows down • OASIS-SAML work (XML to leaven PKI) gains buzz • RSA buys Securant

  18. KX.509 • Software that uses a Kerberos ticket to create a temporary certificate (less than 8 hrs; no revocation; etc.) • Used for authentication to certificate-based local web services (preload campus roots) in Kerberos realms • Out of Michigan; to be polished and released via NMI grant • Two parts: server (KCA) that issues certs; client code to manage incoming cert into stores,OS and applications… • New service (KCT) to issue Kerberos tickets from certs.

  19. The Industry • Browsers that don’t take community roots • Communications tools that want certs we don’t want to give them • Path math that sometimes don’t compute • Technology that doesn’t interoperate...

  20. Higher Education • HEBCA • HEPKI-TAG • HEPKI-PAG • PKI-labs • Campus successes – Texas Med, Dartmouth, MIT…
