1. TERENA TF-EMC2 Workshop David Groep, 2004.11.04 http://www.eugridpma.org/

2. TF-EMC2 meeting, November 4 2004 - 2 David Groep – chair@eugridpma.org A PKI for Grids  PKI model fits the lack of hierarchical relations between users and resources in the Grid  Users can join collaborations (VOs), that are independent of both resources and home organisations  mainly unilateral trust relations (RP/subscriber -> CA) limited mutual trust (CA->CA within PMA)  Both users and services need a credential  Revocation:  of authZ via the VOs,  of AuthN via the CAs (latter only of the identity is compromised)

3. TF-EMC2 meeting, November 4 2004 - 3 David Groep – chair@eugridpma.org The EUGridPMA European Grid Authentication Policy Management Authority for e-Science  Coordinates authentication for people and services for European, national, and related Grid projects EGEE, DEISA, SEEGRID, LCG, …  PMA manages authentication guidelines policies  Trust domain for research and academic grids

4. TF-EMC2 meeting, November 4 2004 - 4 David Groep – chair@eugridpma.org Certificate Authority Coordination  Evolved from the CA Coordination Group in DataGrid, CrossGrid, LCG, …  collection of national and regional CAs  better local identity vetting  national legislation  all meet or exceed minimum requirements  identity checking (in-person, photo-ID)  physical security (signing key protection, storage)  naming (unique certificate names)  revocation (updated lists, retrieval)  Clearly defined accreditation procedure  Basic tools and distribution mechanisms

5. TF-EMC2 meeting, November 4 2004 - 5 David Groep – chair@eugridpma.org Accreditation process  Codification of procedures in a CP(S) for each CA  de facto lots of copy/paste, except for vetting sections  Peer-review process for evaluation  comments welcomed from all PMA members  two assigned referees  In-person appearance during the review meeting

6. TF-EMC2 meeting, November 4 2004 - 6 David Groep – chair@eugridpma.org Accredited Authorities  Everyone (almost) in Europe has a national CA  Green: CA Accredited  Yellow: being discussed Other Accredited CAs:  DoEGrids (US)  GridCanada  ASCCG (Taiwan)  ArmeSFO (Armenia)  CERN  Russia (HEP)  FNAL Service CA (US)  Israel  Pakistan

7. TF-EMC2 meeting, November 4 2004 - 7 David Groep – chair@eugridpma.org The Catch-All CAs Project-centric “catch all” Authorities  For those left out of the rain in EGEE  CNRS “catch-all” (Sophie Nicoud)  coverage for all EGEE partners  For the South-East European Region  regional catch-all CA  For LCG world-wide  DoeGrids CA (Tony Genovese & Mike Helm, ESnet)  Registration Authorities through Ian Neilson

8. TF-EMC2 meeting, November 4 2004 - 8 David Groep – chair@eugridpma.org Distribution RPM distribution to facilitate deployment projects  validation must be done via TACAR (or out-of-band means)  releases contain  CA root cert  CRL URL  CA URL  namespace-policy file (used by software for enforcement)  dependency information (for hierarchical PKIs)  meta-RPMs “ca_policy_eugridpma” for triggering dependencies in install software (yum/apt)  releases every ~ 4-12 weeks

9. TF-EMC2 meeting, November 4 2004 - 9 David Groep – chair@eugridpma.org Global interoperation  PMAs collaborate bilaterally in an interoperation framework: the International Grid Federation see www.gridpma.org Americas PMA being formed EUGridPMA APGridPMA

10. TF-EMC2 meeting, November 4 2004 - 10 David Groep – chair@eugridpma.org Commonality  Common services to all European eInfrastructure  EUGridPMA:  All EU Grid infrastructure FP6 programmes  CAs also cover inter-organisational national projects  TERENA TACAR provides the trust validation  Grid projects rely on TACAR to validate roots-of-trust  Minimum Requirements form bases of IGF  Coherency in AP modelled on EUGridPMA  Americas are planning to build an AMSGridPMA

11. TF-EMC2 meeting, November 4 2004 - 11 David Groep – chair@eugridpma.org Current topics of discussion  Continuing updates to minimum requirements as experience grows to comply better with evolving Grid middleware to comply with evolving industry standards  User key hygiene worries abound Can the user be trusted with key care? (hardly…)  Complexity for users, services the server-certificate service!  On-line CA methodologies Guidelines and Minimum Requirements Site-local solutions (SIPS) Active Certificate Stores (credential repositories, escrow services) CA-generated key pairs and ease-of-use
