Keeping Authorities “Honest or Bust” with Decentralized Witness Cosigning

Bryan Alexander Ford, Linus Gasser, Philipp Svetolik Jovanovic, Nicolas Gailly, Ismail Khoffi

Abstract—The secret keys of critical network authorities – such as time, name, certificate, and software update services – represent high-value targets for hackers, criminals, and spy agencies wishing to use these keys secretly to compromise other hosts. T ...

PriFi: A Low-Latency and Tracking-Resistant Protocol for Local-Area Anonymous Communication

Jean-Pierre Hubaux, Bryan Alexander Ford, Mahdi Zamani, Italo Ivan Dacosta Petrocelli, Ludovic Barman

Popular anonymity mechanisms such as Tor provide low communication latency but are vulnerable to traffic analysis attacks that can de-anonymize users. Moreover, known traffic-analysis-resistant techniques such as Dissent are impractical for use in latency- ...

Flexible Spectrum Assignment for Local Wireless Networks

Julien Pierre Sacha Herzen

In this dissertation, we consider the problem of assigning spectrum to wireless local-area networks (WLANs). In line with recent IEEE 802.11 amendments and newer hardware capabilities, we consider situations where wireless nodes have the ability to adapt n ...

Towards Unconditional Tor-Like Anonymity

Christina Fragouli, László Czap, Iris Safaka

We design and evaluate a traffic anonymization protocol for wireless networks, aiming to protect against computationally powerful adversaries. Our protocol builds on recent key-generation techniques, that leverage intrinsic properties of the wireless toget ...

Secret Communication Over Broadcast Erasure Channels With State-Feedback

Christina Fragouli, Suhas Diggavi, László Czap, Vinod Malathidevi Prabhakaran

We consider a 1-to-K communication scenario, where a source transmits private messages to K receivers through a broadcast erasure channel, and the receivers feedback strictly, causally, and publicly their channel states after each transmission. We explore ...

Distributed Formation Control of Fixed Wing Micro Aerial Vehicles for Uniform Area Coverage

Dario Floreano, Grégoire Hilaire Marie Heitz, Meysam Basiri, Maja Varga

Teams of fixed wing micro-aerial vehicles (MAVs) could provide a wide area coverage and relay data in wireless ad-hoc networks. In such applications fixed wing MAVs have to be able to regulate an inter-robot distance. Fixed wing MAVs have reduced maneuvera ...

Optimal polynomial blow up range for critical wave maps

Can Gao

We prove that the critical Wave Maps equation with target

S^2

and origin ℝ

^{2+1}

admits energy class blow up solutions of the form [ u(t, r) = Q(\lambda(t)r) + \epsilon(t, r) ] where

Q:ℝ²\rightarrow S^2

is the ground state harmonic map and $\lambda ...

Secure Wireless Communications via Cooperative Transmitting

Ninoslav Marina

Information-theoretic secrecy is combined with cryptographic secrecy to create a secret-key exchange protocol for wireless networks. A network of transmitters, which already have cryptographically secured channels between them, cooperate to exchange a secr ...

Topology Optimization For Energy-Efficient Communications In Consensus Wireless Networks

Martin Vetterli, Benjamin Bejar Haro

Over the past years there has been an increasing interest in developing distributed computation methods over wireless networks. A new communication paradigm has emerged where distributed algorithms such as consensus have played a key role in the developmen ...

A 24 GHz Phased-Array Doppler Radar Sensor and Transceiver Front-End for Smart Streetlights

Ban Wang

Recently, European Union advocates the smart Solid-State Lighting (SSL). The key factors are a smart-control scheme and an interaction with other networks, such as communication networks and traffic monitoring sensor networks. Public lighting represents a ...
