Mobile IPv6 Location Privacy Solutions

Mobile IPv6 (RFC 3775) enables mobile nodes to remain reachable while roaming on the Internet. However, the location of a mobile node can be revealed and its movement tracked by simply monitoring the Mobile IPv6 addresses in the IP packets. In this document, we consider the MIP6 location privacy problem described in RFC 4882 and propose efficient and secure techniques to protect the location privacy of a mobile node. This document is a product of the IP Mobility Optimizations (MobOpts) Research Group.
