This memo 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 memo defines an Experimental 
Protocol for the Internet community.

This document is a product of the Host Identity Protocol Working Group of the IETF.

EXPERIMENTAL: This memo defines an Experimental Protocol for the
