Abstract:
As technology advances, more and more mobile devices with versatile communication capabilities hit the market. Many of these devices are multihomed and use standard protocols like IP and TCP, which have been designed for non mobile computers with a single network device. Therefore they are not able to cope with mobility and multihoming appropriately. A bunch of protocols and protocol extensions have been proposed to make TCP/IP go mobile. Amongst them is the host identifier protocol (HIP) which adds an additional protocol layer between TCP and IP to hide host mobility from the transport layer. It offers advanced features like mobility and multihoming support, host authentication, encryption and a cryptographic namespace without requiring changes of the network infrastructure or network applications.
HIPs security concept is based on public key authentication and Diffie Hellman session keys. Unfortunately, these public key operations are complex and costly in terms of CPU power. Lightweight HIP (LHIP) is a HIP protocol extension which enables HIP to offer mobility and multihoming support, without the use of public key cryptography. LHIPs goal is to speed up hit to make it usable for weak mobile devices and large scale servers without introducing weaknesses, attackers could use to disrupt or steal a connection.
This talk will give an overview of HIP and will discuss the lightweight HIP extension in detail.
