| Abstract: | Foreseeable 4G environments will extensively take advantage of the concept of context transfer to provide seamless secure handovers between different administrative domains. However, the utilization of context transfer comes with a cost in the users' privacy. The purpose of this paper is to elaborate on 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. In addition, assuming that the most appropriate form of user identity for the context is the Network Access Identifier (NAI), we show how the employment of temporary NAIs can further increase the privacy of our schemes. |
