Effectiveness of Distance-Decreasing Attacks Against Impulse Radio Ranging

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

We expose the vulnerability of an emerging wireless ranging technology, impulse radio ultra-wide band (IR-UWB), to distance-decreasing attacks on the physical communication layer (PHY). These attacks violate the security of secure ranging protocols that al ...

A Mobile World of Security

Rüdiger Urbanke, Christina Fragouli, Panagiotis Papadimitratos, Christine Neuberg

Mobile users are increasing fast in numbers, new types of services and applications become available, and new mobile systems (e.g., for intelligent transportation) emerge. Meanwhile, the need for securing communication in such large scale, highly dynamic s ...

Not Just for Errors: Codes for Fast and Secure Flash Storage

Yuval Cassuto

Error-correcting codes are normally employed in storage devices to guarantee the integrity of data in the presence of errors. This paper presents two schemes where error-correcting codes are used for entirely different purposes. In the first part of the pa ...

On the Performance of Secure Vehicular Communication Systems

Jean-Pierre Hubaux, Panagiotis Papadimitratos

Vehicular communication (VC) systems are developed primarily to enhance transportation safety and efficiency. Vehicle-to-vehicle communication, in particular frequent cooperative awareness messages or safety beacons, have been considered over the past year ...

Smashing SQUASH-0

Serge Vaudenay, Khaled Ouafi

At the RFID Security Workshop 2007, Adi Shamir presented a new challenge-response protocol well suited for RFIDs, although based on the Rabin public-key cryptosystem. This protocol, which we call SQUASH-0, was using a linear mixing function which was subse ...

Interactive Mobile Robotic Drinking Glasses

Francesco Mondada, François Rey, Michele Leidi

The central idea behind this attempt is to merge common objects and robotics to obtain a new type of interactive artefact, we call robjects. Robjects provide services to everyday life and can be controlled by the user in a very intuitive way. Robjects take ...

Analysis and Optimization of Cryptographically Generated Addresses

Jean-Pierre Hubaux, Joppe Willem Bos, Onur Özen

The need for nodes to be able to generate their own address and verify those from others, without relying on a global trusted authority, is a well-known problem in networking. One popular technique for solving this problem is to use self-certifying address ...

Toward Quantifying System Manageability

George Candea

Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is ...
