Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: RFC Editor <firstname.lastname@example.org>, hip mailing list <email@example.com>, hip chair <firstname.lastname@example.org> Subject: Protocol Action: 'Host Identity Protocol Version 2 (HIPv2)' to Proposed Standard (draft-ietf-hip-rfc5201-bis-20.txt) The IESG has approved the following document: - 'Host Identity Protocol Version 2 (HIPv2)' (draft-ietf-hip-rfc5201-bis-20.txt) as Proposed Standard This document is the product of the Host Identity Protocol Working Group.

Technical Summary: This document specifies the details of the Host Identity Protocol (HIP). HIP allows consenting hosts to securely establish and maintain shared IP-layer state, allowing separation of the identifier and locator roles of IP addresses, thereby enabling continuity of communications across IP address changes. HIP is based on a SIGMA- compliant Diffie-Hellman key exchange, using public key identifiers from a new Host Identity namespace for mutual peer authentication. The protocol is designed to be resistant to denial-of-service (DoS) and man-in-the-middle (MitM) attacks. When used together with another suitable security protocol, such as the Encapsulated Security Payload (ESP), it provides integrity protection and optional encryption for upper-layer protocols, such as TCP and UDP. This document obsoletes RFC 5201 and addresses the concerns raised by the IESG, particularly that of crypto agility. It also incorporates lessons learned from the implementations of RFC 5201. Working Group Summary: There is full consensus behind this document. Document Quality: As discussed in RFC 6538, there are several implementations of the Experimental HIP specs. At least HIP for Linux and OpenHIP will be updated to comply with the standards-track specs. Personnel: Gonzalo Camarillo is the document shepherd. Ted Lemon is the responsible AD.
