  2. Outline • Requirement to access to the GRID • GRID-FR CA • Certificate • Statistics

  3. Requirement to access to GRID • User certificate (authentication) • Access to VO or VOMS (authorization) • User interface or web service access

  4. Outline • Requirement to access to the GRID • About GRID-FR CA • Certificate • Statistics

  5. About GRID-FR CA • CA=Certification Authority • CA GRID-FR • Issue certificates for institutes participating in GRID projects in which CNRS is involved: • EGEE, LCG, DEISA , Grid 5000, ILDG, E-Sciences, Integrative Biology, … • Issue user, server and service certificates to: • French public institutes & private institutes • Foreign public & private institutes, no HEP, and who do not have CA (catch-all).

  6. About GRID-FR CA Composition of a CA • CA : Certification Authority • RA : Registration Authority • EE : End Entity (person, host, service) • Certificate repository • Certificates (EE, CAs) • CRLs • Validation Service • Encipherment Private Key Recovery Service

  7. About GRID-FR CA • GRID-FR sign algorithm • SHA1 • CRL=Certification Revocation List • Generated each night • Lifetime : 1 month • Download dedicated server: • crls.services.cnrs.fr • EUGridPMA requirements • European Policy Management Authority for Grid Authentication (http://www.eugridpma.org) • Activity : • To verify the minimum requirements • To accredit new CAs

  9. Outline • Requirement to access to the GRID • GRID-FR CA • Certificate • Statistics

  10. X509v3 Certificate • asymmetric encryption algorithm • Accredited by the trusted CA • Certificate for : • User • Host • Service • Couple of 2 keys : • Private key • NOT communicated • Encoded and protected by password • Public key (also called certificate) • Signed by CA • Published

  11. Structure of an X509 certificate • Certificate • Version • Serial Number • Algorithm ID • Issuer • Validity • Not Before • Not After • Subject • Subject Public Key Info • Public Key Algorithm • Subject Public Key • Issuer Unique Identifier (Optional) • Subject Unique Identifier (Optional) • Extensions (Optional) • ... • Certificate Signature Algorithm • Certificate Signature (Issuer and subject unique identifiers were introduced in Version 2, Extensions in Version 3)

  12. Example 1/2 Certificate: Data: Version: 3 (0x2) Serial Number: 1323 (0x52b) Signature Algorithm: md5WithRSAEncryption Issuer: C=FR, O=CNRS, CN=GRID-FR Validity Not Before: Oct 3 13:13:42 2006 GMT Not After : Oct 3 13:13:42 2007 GMT Subject: O=GRID-FR, C=FR, O=CNRS, OU=UREC, CN=Alice De Bignicourt Subject Public Key Info: Public Key Algorithm: rsaEncryption RSA Public Key: (1024 bit) Modulus (1024 bit): 00:f6:48:51:86:3f:c3:0e:5a:1d:69:9e:c9:a7:4c: 25:d8:a1:e7:5a:9c:6f:50:d4:d6:34:ab:3f:57:a7: 60:d9:f1:3d:58:43:3a:ca:90:fb:51:9d:2f:4a:3e: 10:d4:14:4e:48:ca:6b:9f:d0:ac:f0:b5:94:bb:15: d6:43:49:91:37:72:75:0e:1b:89:d2:7c:76:db:25: 60:d1:fd:fc:b5:20:78:18:cb:11:a3:73:9a:e3:2b: ab:a3:cd:7c:0c:6c:9a:3a:19:5e:cb:10:e6:66:f4: 8e:02:aa:8f:1b:12:e0:f8:42:5e:68:a8:53:1b:f6: c6:00:92:f0:76:77:6b:f9:cd Exponent: 65537 (0x10001) Serial Number CA Issuer Validity Subject Public Key

  14. Information in the X509 certificate • Information • Subject = Distinguish Name (DN) • Identifier in the Grid • Lifetime • Date not bedore • Date not after • Extensions  the use of the certificate • Common filename extensions for X.509-certificates are : • .PEM • 2 files : public key, private key protected • .P7C - PKCS#7 • Certificates or CRLs • .P12 - PKCS#12 • 1 file : 2keys, protected • Also : CER DER P7B

  15. How to obtain a GRID-FR certificate ? • Requestor • Generates : • private key • public key • Sends public key • RA (Registration Authority = GRID-FR manager) to verify & valid • Public key is signed and certificate issued • Requestor get back the certificate
