8 Apr 10:15 Andrei Gurtov: Introduction to Host Identity Protocol (HIP)

Dr Andrei Gurtov from the Helsinki Institute for Information Technology HIIT gives a demonstration lesson for a vacant professorship in computer science (networking and distributed systems) being filled at our department. The lesson will be given in English on Wednesday 8 April, at 10.15 in room C222. Welcome.

The title of the demonstration lesson: Introduction to Host Identity Protocol (HIP)

Historically, the Internet architecture is based on an assumption that hosts are stationary and assigned a permanent IP address that does not change. This assumption does not hold in the present days when billions of users access Internet from mobile phones and portable computers over cellular and WiFi links. The concept of identifier-locator split has been proposed to separate the role of host identifier (a permanent host
name) and locator (an IP address telling where the host is attached to the network at the moment). Host Identity Protocol (HIP) is one instantiation of identifier-locator split developed at the Internet Engineering Task Force (IETF). HIP employs cryptographic host identities to secure the mapping between host names and addresses to enable host mobility and multihoming (simultaneous use of several network links). In this lecture, we outline the present Internet problems, introduce HIP architecture and base protocol, and make a short demonstration of HIP in action.

The lecture is designed for students specializing in distributed systems and networks, who have basic knowledge of Internet protocols and network security. Welcome!
