A Practical Approach to provide Communication Privacy

Privacy and security are important features for the future mobile wireless Internet since users expect a privacy level comparable to that of today´s cellular networks. Separating identifiers from locators is a current practice in today´s new network protocols and is a small step on the right direction. However, the separation must be maintained in the presence of an intruder who eavesdrops or manipulates the traffic. In this paper we present a generic framework that targets these problems at the network layer. We further instantiate this framework with an example architecture using well-known protocols which support mobility.
