Efficient Key Exchange for Wireless Multi-hop Networks

Christina Fragouli, László Czap, Iris Safaka

We present a protocol that enables to create pairwise keys between nodes in a wireless network, so that the keys are secure from an adversary, Eve, with unbounded computational and memory capabilities, but with limited network presence. Our proposed protoc ...

Transparency Instead of Neutrality

Adrian Perrig, Christos Pappas

The technical community has so far defined network neutrality in terms of specific mechanisms, e.g., policing or shaping. We argue that these definitions are problematic: according to them, a non-neutral network may be preferable (for all users) to a neutr ...

Hiding Information in Multiple Level-line Moirés

Roger Hersch, Thomas Walger

Secure documents often comprise an information layer that is hard to reproduce. Moiré techniques for the prevention of counterfeiting rely on the superposition of an array of transparent lines or microlenses on top of a base layer containing hidden informa ...

Towards a versatile European Driver Advisory System

Daniel Emery

The paper describes a concept for a Versatile Driver Advisory System (VDAS). The on-board part of this system is not only fully compatible with a European Driver Advisory System (EDAS) coming from Traffic Management Systems (TMS) but also with other DAS (N ...

Creating Secrets out of Erasures

Christina Fragouli, Suhas Diggavi, Panagiotis Kostopoulos

Current security systems often rely on the adversary's computational limitations. Wireless networks offer the opportunity for a different, complementary kind of security, which relies on the adversary's limited network presence (i.e., that the adversary ca ...

Compute-and-Forward: Multiple Bi-directional Sessions on the Line Network

Michael Christoph Gastpar, Jasper Goseling

Signal superposition and broadcast are important features of the wireless medium. Compute-and-Forward, also known as Physical Layer Network Coding, is a technique exploit- ing these features in order to improve performance of wireless networks. In this pap ...

Wireless Multi-hop Networks Beyond Capacity

Patrick Thiran, Adel Aziz

Wireless multi-hop local area networks use in general scheduling schemes that assume the network capacity to be known. Indeed in most of the throughput-optimal algorithms the sources are assumed to send at a rate within the capacity region. However, measur ...

Formal Analysis of Secure Neighbor Discovery in Wireless Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

We develop a formal framework for the analysis of security protocols in wireless networks. The framework captures characteristics necessary to reason about neighbor discovery protocols, such as the neighbor relation, device location, and message propagatio ...

QUILT: A Decode/Quantize-Interleave-Transmit Approach to Cooperative Relaying

Christina Fragouli, Suhas Diggavi, Siddhartha Brahma, Ayan Sengupta, I-Hsiang Wang

Physical layer cooperation of a source with a relay can significantly boost the performance of a wireless connection. However, the best practical relaying scheme can vary depending on the relative strengths of the channels that connect the source, relay an ...

Building Wireless Network Coding Protocols

Lorenzo Keller

This work studies how to build wireless network protocols that achieve better reliability, lower delay and higher throughput than existing alternatives by using network coding and by exploiting the broadcast nature of the wireless channel. In the first par ...
