  1. The Classic X.509 Profile Updateand other assorted issuesDavid Groep, July 2007

  2. Classic X.509 AP updates (v4.1) Major points addressed in 4.1 • explicit definition of what we mean with “should” • FQDN “ownership” • maximum 5 years without any kind of checking • reformulated on-line CA architectures • includes explicitly the two pre-vetted architectures • keyUsage SHOULD (was MUST) be critical in CA certs • compliance with Grid Certificate Profile draft (in OGF)

  3. Classic v4.1 Updates (1) • clearer definition of what we mean by should • FQDN ‘ownership’ • A form of validation after at most five years this has been buried in very old minutes and has now been made explicit

  4. Classic v4.1 Updates (2) • On-line CA architectures

  5. Classic v4.1 Updates (4) • keyUsage extensions SHOULD be critical in a CA cert • this used to be a MUST, but that would unnecessarily exclude some commercial top-level CAs (e.g., NetTrust) • Compliance with Grid Certificate Profile document • document is now in draft in the OGF CAOPS-WG • almost finished • embodies lots and lots of community knowledge on what a certificate ought to look like • read it before you setup a new CA, or regenerate a root cert, or think about an end-entity certificate profile • Auditing: if you re-issue without a new identity vetting, you MUST keep the original records for at least as long as there are certs based on this vetting plus the default grace period

  6. Classic v4.1+ - what is still pending • Still pending for a next version • some real insights in the necessary site security measures • certificate/crl profile to be revised once the OGF document thereon is formally published • language clarification on documented traceability in various places

  7. Other (non-) contentious issues discussed in TR • CRLs for compromised CAs • non-repudiation bit in keyUsage • and how that relates to email signing • the Meaning of Locality • and why to use O if you can • objectSigning bits • should we also address who is allowed to get this bit? • should the organisation be involved (Milan)? • or does it only asserts that the code was signed by this user, as is done in the UK, NL, AT and so better keep as is? • Prepare the profile a bit better for Robot certificates • CDP in EE certificates ought to point to a DER CRL • auditable tracability in ID vetting and alternative solutions – and the meaning of SHOULD

  8. TACAR the TERENA Academic CA Repository • trusted and centralized place • where root CA certs can be stored and safely retrieved • which is policy-neutral (but ‘IGTF-ready’) for CAs • directly managed by TERENA members • belonging to a national academic PKI in member states • for all CAs set-up to support not-for-profit research, in which the academic community is directly involved

  9. IGTF Distribution in Other Formats • Apart from validation via TACAR, the IGTF manages a distribution of all accredited authorities • formerly known as Anders’ RPM set, today also available as: JKS, tar-gz, configure && make, … • usually built by the EUGridPMA (me, actually) • mirrored twice-daily to the apgridpma.org site • copied and re-distributed by downstream vendors (EGEE/LCG, VDT, …) • also contains the fetch-crl utility (now at version 2.6.3) • Download locationhttps://dist.eugridpma.info/distribution/

  10. Some dates for you to remember and schedule • September 4-5, 2007 TF-EMC2 meeting, Prague, CZ • September 19-21, 2007 11th EUGridPMA meeting, Thessaloniki, GR • October 15-19 – OGF 21 CAOPS, IGTF, …, Seattle (WA), USA • January 14-16, 2007 12th EUGridPMA meeting, Amsterdam, NL
