MMIP — Mixed Mobile Internet Protocol

Mobile IP extends the Internet Protocol to provide mobility features. Unfortunately, Mobile IP introduces new security threats unknown in IP environments. In this paper we emphasize on the problem of ensuring location privacy for mobile users which is not addressed by Mobile IP. To conceal movements of mobile users and to prevent an attacker from tracing users’ locations we designed and implemented a simple extension of Mobile IP which is called Mixed Mobile IP. The basic idea of the proposed extension is to separate information about the identity of a host from information about its location. The paper presents the main features of the protocol and sketches our Linux-based prototype implementation.     «
