An Enhanced Location Privacy Framework with Mobility Using Host Identity Protocol

Location privacy is one of the problems involved in IP mobility. There are two proposed frameworks for this problem based on Host Identity Protocol (HIP); HIP Location Privacy Framework provides partial location privacy with mobility, while BLIND provides complete location privacy without mobility. In this paper, we integrate their strong points, i.e. complete location privacy with mobility. Our framework gives a way to decouple identifiers for mobility from identifiers for end-to-end communications. We construct an extensional mobility management protocol of BLIND, and discuss a trade-off in terms of efficiency and operational cost.
