Enhancing Location Privacy in MobileIPv6 by Distributed Home Agents
Hiroyuki Takahashi, Takashi Minohara (Takushoku Univ.) CPSY2009-91 DC2009-88
Abstract (in Japanese) (See Japanese page) 
(in English) Mobile IP allows nodes to keep reachability and on-going connections to correspondent nodes while moving around in the Internet. In order to continue communication a mobile node sends Binding Update to its Home Agent every time it moves. Since the source and destination address of a binding update are clear to nodes between a mobile node and its home agent, it exists location privacy risks. A third person could trace movements of mobile nodes by linking binding updates with their destination addresses. In this paper, we propose extensions to Mobile IPv6 to protect location privacy. Multiple home agents allow mobile nodes to permutate destinations of binding updates. We have implemented a prototype system by extending the UMIP (USAGI-patched Mobile IPv6 for Linux), and conducted some experiments. The results show that only communication delays for traversing the additional path are observed.
