Wireless Network Secrecy with Public Feedback

Emre Telatar, Suhas Diggavi, Etienne Perron

In this paper we consider secret communication between two special nodes ("source" and "destination") in a wireless network with authenticated relays: the message communicated to the destination is to be kept information-theoretically (unconditionally) sec ...

On Cooperative Wireless Network Secrecy

Emre Telatar, Suhas Diggavi, Etienne Perron

Given that wireless communication occurs in a shared and inherently broadcast medium, the transmissions are vulnerable to undesired eavesdropping. This occurs even when a point-to-point communication is sought, and hence a fundamental question is whether w ...

Impact of Denial of Service Attacks on Ad Hoc Networks

Jean-Pierre Hubaux, Imad Aad

Significant progress has been made towards making ad hoc networks secure and DoS resilient. However, little attention has been focused on quantifying DoS resilience: Do ad hoc networks have sufficiently redundant paths and counter-DoS mechanisms to make Do ...

Person Authentication using Brainwaves (EEG) and Maximum A Posteriori Model Adaptation

José del Rocio Millán Ruiz, Sébastien Marcel

In this paper, we investigate the use of brain activity for person authentication. It has been shown in previous studies that the brain-wave pattern of every individual is unique and that the electroencephalogram (EEG) can be used for biometric identificat ...

Key Agreement in Peer-to-Peer Wireless Networks

Jean-Pierre Hubaux, Mario Cagalj, Srdan Capkun

We present a set of simple techniques for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol, which is known to be vulnerable to the ``man-in-the-middle" attack if the two users ...

Thwarting selfish and malicious behavior in wireless networks

Mario Cagalj

Security is at the core of any communication system and, in particular, of wireless (radio) networks. In this thesis, we focus on three important security aspects in the framework of wireless networks: selfish (noncooperative) behavior at the Medium Access ...

Fuelling WiFi deployment: A reputation-based solution

Jean-Pierre Hubaux, Naouel Ben Salem

The rapid growth of WiFi over the past two years reveals the willingness of the Wireless Internet Service Providers (WISPs) to develop this technology and the interest of the users in this new service. However, the lack of unified roaming slows down the de ...

Key agreement over a radio link

Jean-Pierre Hubaux, Mario Cagalj

We present a simple, and yet powerful, technique for key establishment over a radio link in peer-to-peer networks. Our approach is based on the Diffie-Hellman key agreement protocol. This protocol is known to be vulnerable to the ``man-in-the-middle" attac ...

Cooperation in Multi-hop Cellular Networks

Jean-Pierre Hubaux, Naouel Ben Salem, Levente Buttyan

Naouel Ben Salem, Levente Buttyan, Jean-Pierre Hubaux and Markus Jakobsson abstract: In multi-hop cellular networks, the existence of a communication link between the mobile station and the base station is not required: a mobile station that has no direct ...
