When 1 a user roams into a foreign network, in addition to data confidentiality, mutual authentication between the user and the provider is also a vital issue. These concerns and the desire to stay seamlessly connected lead to the demand of fast authentication and key establishment mechanisms, which are particularly difficult in inter-domain handover scenarios. In this paper, we introduce a novel mechanism to provide a simple but effective method, which forwards the key from the previous access router to the new access router that the mobile node attaches to. With this mechanism, trust relationship can be re-established even if the access routers do not trust each other in such an inter-domain scenario. Compared with the classical authentication method used in GSM and a recently proposed EAP-based secure key exchange protocol, our approach shows advantages of faster key exchange and authentication with only minimal message exchange in the wireless link.

However, even today, it is equally important for the measures employed to be energy efficient. For this reason, this publication analyzes the suitability of various cryptographic primitives for use in WSNs according to various criteria and, finally, describes a modular, PKI-based framework for confidential, authenticated, secure communications in which most suitable primitives can be employed. Due to the limited capabilities of common WSN motes, criteria for the selection of primitives are security, power efficiency and memory requirements. The implementation of the framework and the singular components have been tested and benchmarked in our testbed of IRISmotes.

Privacy can be divided into two types: identity anonymity and location privacy. Identity anonymity has been addressed in many MANET routing protocols while location privacy still requires appropriate solutions. Even in ID anonymous routing protocols, a strong enough traffic analyser can track the nodes&#39; locations in active routes (Wang and Hu, 2005). If he discovers his favourite information about the location of network elements, he might be able to damage the communication that the network was designed for. The adversary could infer such information by tracing some message flows to discover their origin using an appropriate set of directional antennas. In this paper, we will propose a solution to achieve the destination&#39;s location privacy against a global eavesdropper. We use privacy analysis and simulation to study the anonymity and the routing performance of the proposed approach.

Anonymity, location privacy and unlinkable communication are important privacy aspects specially in wireless environments. A potential eavesdropper may launch traffic analysis to infer privacy related information of the network. Meanwhile, the characteristics of wireless ad hoc networks such as the limited resources or dynamic topology make providing privacy very challenging in MANETs and privacy in such networks can not be achieved without appropriate protection schemes. In this paper, we propose an anonymous multicast routing protocol for mobile ad hoc networks. Our protocol extends anonymous routing from unicast communication to multicast scenarios and also provides additional privacy properties.
