The Host Identity Protocol (HIP) is being standardized by the IETF as a new solution for host mobility and multihoming in the Internet. RFCs 5201-5207 on HIP are recently published by the IETF. HIP uses self-certifying public-private key pairs in combination with IPsec to authenticate hosts and protect user data. HIP is an important component of several P2P systems, including P2PSIP; P2P systems such as DHT and i3 are core part for mapping host identifiers to locators.
The tutorial covers the current problems in Internet architecture, the identifier/location split, the base HIP protocol including the base exchange, new IPsec mode, DNS and rendezvous extensions, infrastructure for resolving host names to locators, micromobility, privacy, and support of legacy applications. We will as well go through current implementations, HIP testbeds, including a pilot deployment of HIP in Boeing airplance factory. The tutorial is based on a book A. Gurtov, Host Identity Protocol (HIP): Towards the Secure Mobile Internet, ISBN 978-0-470-99790-1, Wiley and Sons, June 2008. (Hardcover, 332 p).
A following quotation from the book foreword by Jari Arkko, Internet Area Director, IETF motivates the interest behind the topic: "Bob Moskowitz pioneered the idea of the Host Identity Protocol (HIP) in late 1990s. While the general idea of separating identifiers and locators had been around for a long time, nothing quite as detailed and comprehensive had actually been designed before. The initial designs were little more than sketches but the architecture was appealing. In particular, many people were drawn to the idea of HIP due to the way that security was naturally integrated as a part of the design, or the fact that the same powerful concepts appeared to be capable of solving many different problems, be it about mobility, multihoming, address translation, or stable anchor points..."
Andrei Gurtov received his M.Sc and Ph.D. degrees in Computer Science from the University of Helsinki, Finland. At the present, he is Principal Scientist leading the Networking Research group at the Helsinki Institute for Information Technology focusing on the Host Identity Protocol and next generation Internet architecture. He is co-chairing the IRTF research group on HIP and teaches as an adjunct professor at Telecommunications and Multimedia Laboratory of the Helsinki University of Technology. Previously, his research focused on the performance of transport protocols in heterogeneous wireless networks. In 2000-2004, he served as a senior researcher at Sonera Finland contributing to performance optimization of GPRS/UMTS networks, intersystem mobility, and IETF standardization. In 2003, he spent six months as a visiting researcher in the International Computer Science Institute at Berkeley working with Dr. Sally Floyd on simulation models of transport protocols in wireless networks. In 2004, he was a consultant at the Ericsson NomadicLab. Dr. Gurtov is a co-author of over 50 publications including research papers, patents, and IETF RFCs.
