Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the lighting levels, but they also affect ...

Destination buffer analysis for packets rejection obliteration in multi-channel networks

Georgia Fragkouli

In this paper we study a multi-channel network, each station of which is equipped with a network interface that has a receiver buffer of multiple packets. In this way, each station is able to receive multiple packets per time instant. We adopt a synchronou ...

A Timing-Monitoring Sequential for Forward and Backward Error-Detection in 28 nm FD-SOI

Andreas Peter Burg, Adam Shmuel Teman, Jeremy Hugues-Felix Constantin, Andrea Bonetti

The increasing impact of variability on near-threshold nanometer circuits calls for a tighter online monitoring and control of the available timing margins. Error-detection sequentials are widely used together with error-correction techniques to operate di ...

Security of Distance-Bounding: A Survey

Serge Vaudenay, Srdan Capkun, Martin Benjamin, Gildas Avoine, Aslan Tchamkerten, Ioana Cristina Carlson

Distance-bounding protocols allow a verifier to both authenticate a prover and evaluate whether the latter is located in his vicinity. These protocols are of particular interest in contactless systems, e.g. electronic payment or access control systems, whi ...

Challenges in Distance Bounding

Serge Vaudenay

Smartcard-based protocols represent an increasingly large share of the wireless authentication market, from contactless payments to remote car unlocking. Unfortunately, relay attacks pose a significant threat to these wireless solutions. However, this risk ...

Practical and Provably Secure Distance-Bounding

Serge Vaudenay, Aikaterini Mitrokotsa

From contactless payments to remote car unlocking, many applications are vulnerable to relay attacks. Distance bounding protocols are the main practical countermeasure against these attacks. In this paper, we present a formal analysis of SKI, which recentl ...

Time- and Space-Efficient Sliding Window Top-k Query Processing

Karl Aberer

A sliding window top-k (top-k/w) query monitors incoming data stream objects within a sliding window of size w to identify the k highest-ranked objects with respect to a given scoring function over time. Processing of such queries is challenging because, e ...

Optimal Proximity Proofs Revisited

Serge Vaudenay, Handan Kilinç Alper

Distance bounding protocols become important since wireless technologies become more and more common. Therefore, the security of the distance bounding protocol should be carefully analyzed. However, most of the protocols are not secure or their security is ...

Optimal Proximity Proofs

Serge Vaudenay

Provably secure distance-bounding is a rising subject, yet an unsettled one; indeed, very few distance-bounding protocols, with formal security proofs, have been proposed. In fact, so far only two protocols, namely SKI (by Boureanu et al.) and FO (by Fisch ...

Location leakage in distance bounding: Why location privacy does not work

Serge Vaudenay, Aikaterini Mitrokotsa

In many cases, we can only have access to a service by proving we are sufficiently close to a particular location (e.g. in automobile or building access control). In these cases, proximity can be guaranteed through signal attenuation. However, by using add ...

Asynchronous detection of error potentials

Inaki Asier Iturrate Gil

Recent developments in brain-machine interfaces (BMIs) have proposed the use of errorrelated potentials as cognitive signal that can provide feedback to control devices or to teach them how to solve a task. Due to the nature of these signals, all the propo ...

On Modeling Terrorist Frauds

Serge Vaudenay

Quite recently, distance-bounding protocols received a lot of attention as they offer a good solution to thwart relay attacks. Their security models at still unstable, especially when considering terrorist fraud. This considers the case where a malicious p ...

On the Pseudorandom Function Assumption in (Secure) Distance-Bounding Protocols

Serge Vaudenay, Aikaterini Mitrokotsa, Ioana Cristina Carlson

In this paper, we show that many formal and informal security results on distance-bounding (DB) protocols are incorrect/incomplete. We identify that this inadequacy stems from the fact that the pseudorandom function (PRF) assumption alone, invoked in many ...

A Note on a Privacy-Preserving Distance-Bounding Protocol

Aikaterini Mitrokotsa, Jean-Philippe Aumasson

Distance bounding protocols enable a device to establish an upper bound on the physical distance to a communication partner so as to prevent location spoofing, as exploited by relay attacks. Recently, Rasmussen and Cˇapkun (ACM-CCS’08) observed that these ...

Distance Bounding with IEEE 802.15.4a: Attacks and Countermeasures

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski

Impulse Radio Ultra-Wideband, in particular the recent standard IEEE 802.15.4a, is a primary candidate for implementing distance bounding protocols, thanks to its ability to perform accurate indoor ranging. Distance bounding protocols allow two wireless de ...

Energy-Efficient Transmission Scheduling With Strict Underflow Constraints

David Shuman

This paper considers a single source transmitting data to one or more receivers/users over a shared wireless channel. Due to random fading, the wireless channel conditions vary with time and from user to user. Each user has a buffer to store received packe ...

Secure Neighbor Discovery and Ranging in Wireless Networks

Marcin Poturalski

This thesis addresses the security of two fundamental elements of wireless networking: neighbor discovery and ranging. Neighbor discovery consists in discovering devices available for direct communication or in physical proximity. Ranging, or distance boun ...

Reid et al.'s distance bounding protocol and mafia fraud attacks over noisy channels

Christos Dimitrakakis

Distance bounding protocols are an effective countermeasure against relay attacks including distance fraud, mafia fraud and terrorist fraud attacks. Reid et al. proposed the first symmetric key distance bounding protocol against mafia and terrorist fraud a ...

Neighbor discovery with reception status feedback to transmitters

Ramin Khalili

Neighbor discovery is essential for the process of self-organization of a wireless network, where almost all routing and medium access protocols need knowledge of one-hop neighbors. In this paper we study the problem of neighbor discovery in a static and s ...

Castor: Scalable Secure Routing for Ad Hoc Networks

Karl Aberer, Panagiotis Papadimitratos, Zoran Despotovic, Wojciech Galuba, Marcin Poturalski

Wireless ad hoc networks are inherently vulnerable, as any node can disrupt the communication of potentially any other node in the network. Many solutions to this problem have been proposed. In this paper, we take a fresh and comprehensive approach that ad ...
