  3. Architecture • Presentation http://www.projectdploy.com/draft-dploy-requirements-00.pdf • Review and discussion Pki4ipsec-nov03-agenda

  4. Current Profile Text/Thought • draft-ietf-ipsec-pki-profile-03.txt – Korver • Dploy draft – Gregory Lebovitz http://www.projectdploy.com/draft-dploy-requirements-00.pdf • Certificate Handling Profiles – P. Hoffman http://www.vpnc.org/ipsec-pki-profile.pdf • Clarifying questions on Current Text Pki4ipsec-nov03-agenda

  5. Scope • IPsec Scenarios: s2s VPN and Secure Remote Access VPN • CMC as the certificate lifecycle management protocol Pki4ipsec-nov03-agenda

  6. Proposed Charter Items • Requirement Document • Profile Documents • Certificate Format & Contents • Certificate Usage and IPsec Payloads (IKEv1, IKEv2) • Certificate Request/Retrieval by IPsec Peer • Certificate Lifecycle Management (renewal, revocation, validation • Implementation and Interoperability report Pki4ipsec-nov03-agenda

  7. Timeline • 1 year Pki4ipsec-nov03-agenda

  8. Next Steps Pki4ipsec-nov03-agenda

  9. BACKUP SLIDES FOLLOW Pki4ipsec-nov03-agenda

  10. Open Issues • IKEv1 and IKEv2? in one doc or two docs? • V1 - Need a way to determine which of potentially many certs is end entity cert. Could send EECert as first one? • V1 Should ID_ipv4/v6_addr, ID_FQDN, ID_USER_FQDN all be MUSTs? Right now only _ADDR is MUST. Is that enough for broad interop? Pki4ipsec-nov03-agenda

  11. Need ID for… • How to find EE cert • To lookup policy for IKE • Authentication – understand who the sender claims to be, and use to verify they are who says they are • Authorization - To determine IPsec Access Control and treatment • Logging / Auditing – something meaningful to the network/device operations teams Anything else missing? Pki4ipsec-nov03-agenda

  12. Places to Find ID Elements • IKE ID Payload • Cert – SubjectAltName types • Cert – DN fields/types • Any one, or combo Pki4ipsec-nov03-agenda

  13. IKEv1 Checking Options • Fill in IKE ID payload /w something in Cert SubjectAltName and check that the two match • Just present Cert, and let receiving peer’s local policy determine what they extract and use as ID • Fill in ID w/ something to match IKE SPD entry on receiving peer, then use some SubjectAltName field (as defined by local policy) to do ACL lookup and IPsec SA setup Pki4ipsec-nov03-agenda

  14. IKEv1 and IKEv2 • IKEv1 – we will spend most of our time profiling for IKEv1. We will prioritize this. • IKEv2 Pki4ipsec-nov03-agenda

  15. Revocation • Philosophy question: • Do we profile use of PKI for authorization Pki4ipsec-nov03-agenda

  16. Contentious Issues to Decide Issue • Revocation Method and Impact on Cert contents and IKE payloads • Identity and its correlation to Authentication and Authorization • Do Request and Retrieval Impact the format and payloads document? Or orthogonal. Pki4ipsec-nov03-agenda
