  1. EESSI Deliverables: An IETF Perspective Dr. Stephen Kent Chief Scientist - BBN Technologies Co-chair: PKIX WG - IETF

  2. What is PKIX? • Internet Engineering Task Force (IETF) working group • Membership is defined by mail list participation, not live meetings, although we do meet 3 times each year, along with the rest of the IETF WGs • Recent meeting attendance is ~75-80 people, but it has been as high as 200 • PKIX = PKI for X.509 (as distinguished from PKI based on any other certificate format) • PKIX profiles X.509 documents and creates its own PKI standards

  3. EESSI Deliverables & PKIX (1/2) • Policy Requirements for CAs issuing Qualified Certificates • IETF generally focuses on technical, not policy, matters • Profile for Qualified Certificates • based on RFC 3039 • Security Requirements for Trustworthy Systems managing Certificates for Electronic Signatures • a Common Criteria topic • Security Requirements for Secure Signature Creation Devices • a Common Criteria topic

  4. EESSI Deliverables & PKIX (2/2) • Electronic Signature Formats • RFC 2630 (CMS) • Signature Creation Process and Environment • a Common Criteria topic • Procedures for Electronic Signature Verification • RFC 3280 (path validation) • RFC 2560 (OCSP) • Internet Draft in progress (SCVP) • Time-stamping Profile • based on RFC 3161

  5. A Difference in Focus • PKIX addresses PKI issues in a much broader context, not only legally binding signatures • IPsec • SSL/TLS • S/MIME • PKIX does not address non-protocol aspects of PKI use, e.g., assurance standards, policies, etc. • Differences in certificate status models relative to interpretation of German digital signature regulations?

  6. The Bottom Line • EESSI deliverables defined to date are very closely aligned with PKIX standards wherever there is overlap • Differences exist in focus & scope of WG activities • PKIX emphasizes protocol standards for interoperability in broad Internet context, for a wide range of applications • EESSI encompasses broad range of issues associated with legally binding digital signatures
