1. Day 3 Roadmap and PKI Update

2. When do we get to go home? Report from the BoFs CAMP assessment, next steps PKI technical update Break Research Issues in Middleware Wrap up

3. PKI Technical Update Some emerging distinctions The apps - authn, web authn, s/mime, signed docs, vpn’s, SEVIS The technical basics XKMS and other leavenings KX.509 and Grid Policies and levels of assurance Revisiting revocation – OCSP, CRL, none HE Bridge CA, NIH pilot CREN CA

4. Some emerging themes end-entity vs enterprise PKI X.509 versus non X.509 end-entity new problems: what you see is not what you signed…

5. Why PKI? 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

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

7. The apps VPN’s Enterprise authentication App authentication (the web, some Grids, etc.) Encrypted email Signed email and docs SEVIS (http://www.ins.usdoj.gov/graphics/services/tempbenefits/sevp.htm)http://www.ins.usdoj.gov/graphics/services/tempbenefits/sevp.htm

8. D. Wasley’s PKI Puzzle

9. The Four Planes of PKI 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

10. The Four Planes are 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...

15. Healthcare 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

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

17. European Efforts 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

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.
