Host Identity Protocol
 Idea: transport protocols bind to a hash of
the host identity key, instead of IP address
 Secure mobility without a need for a centralized
public key infrastructure
 Provides support for mobility, multi-homing
 HIIT active with HIP since 2001, co-author of
IETF specs, the Linux implementation
 IETF working group, IRTF research group
 HIP considered as an architectural piece for
Ambient Networks and Daidalos EU projects,
Internet control plane (Boeing/UCB)

Tekes Infrastructure for HIP Project
 Partners: HIIT, TKK, Nokia, Ericsson,
Operator x, Finnish Defence Forces
 2,5 years, late 2004-2007
 Project Goals
 Study the use of Distributed Hash Tables and
overlay networks for HIP
 Finalize HIP Linux, release as open source
 IETF work on rendezvous, DNS
 Develop native HIP API
 Multiple ids on a single host
 Prototype HIP process migration
 HIP in corporate sector

Current Progress
 Prototype of Host Identity Indirection
Infrastructure (Hi3)
 Use of the Internet Indirection Infrastructure as
a control plane for HIP
 Hiding IP addresses for DoS protection until the
handshake is completed
 Solves the initial rendezvous and double-jump
problems
 Setup of PlanetLab testbed in HIIT
 450 servers worldwide for testing of distributed
applications
