  1. www.DOEGrids.orgDOE’s PKI service for Grids Tony J. Genovese Malaga, Spain November 2003

  2. Outline • Grids AuthN/AuthZ model • International Grid Federation efforts • DOEGrids Federation • Experimental OCSP service

  3. Grids AuthN/AuthZ • Separate the two problems • First focus on solving identity • Harmonize identities policies • Standard efforts: GGF, Grid PMA • Grid identity Federations: EDG, Cross Grid, DOEGrids • Other federations: TERENA, EGEE, eInfrastructure? • Authorization still research topic • Individual grids developing own polices • VOMS, Proxy services

  4. International Grid Federation • WWW.GridPMA.org • Informal confederation • Representatives from Major Grid PMAs • European Data Grid and Cross Grid PMA • NCSA Alliance • DOEGrids PMA • NASA Information Power Grid • TERENA • Asian Pacific PMA • AIST, Japan • SDSC, USA • KISTI, Korea • BII, Singapore • Kasetsart Univ., Thailand • CAS, China

  5. DOEGrids Federation • Managed by multiple stake holders • 15 member Policy Management Authority Representing DOE and NSF • PMA Responsible for Certificate Policy and Certification Practice statement • PMA Manages operator relationship • Operator: ESnet at Lawrence Berkeley National Laboratory • Peers with European Data Grid PMA and the Cross Grid project • 20+ Registration Authority Agents

  6. DOEGrids community * Includes DOESG transitioned Certificates

  7. DOEGrids usage

  8. General PKI Service Architecture ESnet Root CA ESnet only signs subordinate CAs Certificate Authority links WWW.ES.net/CA WWW.DOEGrids.org/CA DOEGrids VO support Integrated Site AuthN K/X509 (FNAL) NERSC NIM Integration Virtual Secure Card (SLAC) ESnet subordinate Certificate Authorities and proposed CAs

  9. DOEGrids Physical Security Architecture Vaulted Root CA

  10. DOEGrids PKI roles • Policy Management Authority • Manages PKI policies • Security Officer • Manages PKI infrastructure • Responsible for implementing PKI policies • Registration Authority • Represents VO on PMA • Responsible for identity vetting of VO members • Registration Agent • Delegated identity vetting from RA • Grid Administrator (new) • Delegated by Agent to issue Service Certificates

  11. Grid Admin Role Grid Admin Server Cert Interface Provide PKCS#10 Server Request and submit SSL Client Authentication Using DOEGrids CA certificate failed Authentication Error successful GridAdmin LDAP Request Validation & Authorization process against GridAdmin LDAP Successful? No Authorization Error Yes Issue Server Certificate

  12. Experimental OCSP service Machine B Machine A OCSP Service *edg-fetch-crl-cron downloads all the CRLs listed on EDG website into /opt/edg/certificates folder OCSP Service OCSP Admin Interface *postcrl_ocsp checks if the file is new for every CRL file ( *.r0)under /opt/edg/certificates folder Parse the CRL file and filter only base64 encoded CRL portion. *OCSP Service LDAP Apply URL encoding logic Post this CRL data into OCSP Service Admin interface (SSL Client Authentication *All the CA certificates listed on http://marianne.in2p3.fr/datagrid/ca/ca-table-ca.html has been installed with OCSP Service * edg-fetch-crl-cron & postcrl_ocsp are cron job runs every night
