Privacy Protection in Context Transfer Protocol

Privacy Protection in Context Transfer Protocol
In the future 4G wireless networks will span across different administrative domains. In order to provide secure seamless handovers in such an environment the Context Transfer Protocol is an attractive solution. However, the aforementioned protocol arises some privacy issues concerning the location and movement of users roaming between administrative domains. The purpose of this paper is to present and analyze these privacy issues and propose two privacy enhanced context transfer schemes that alleviate these problems. In the first scheme the Mobile Node (MN) is responsible for the transmission of the context to the new domain. In the second scheme the Home Domain (HD) of the user forwards the context acting as a proxy between the old and the new domain. While the second scheme is expected to be more useful towards realizing seamless handovers, the first one poses less signaling load to the HD. In addition, assuming that the most appropriate form of user identity for the context is the...
