Characterization of the secrecy region of a single relay cooperative system

Ninoslav Marina

Security is an important aspect for the future wire- less networks. Since the number of network nodes increases con- stantly, and, in addition, the networks are decentralized and ad- hoc in nature, it becomes more challenging to apply the current cryptogra ...

On the Tradeoff between Trust and Privacy in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Maxime Raya, Reza Shokri

As privacy moves to the center of attention in networked systems, and the need for trust remains a necessity, an important question arises: How do we reconcile the two seemingly contradicting requirements? In this paper, we show that the notion of data-cen ...

Interpreting Hash Function Security Proofs

Juraj Sarinay

We provide a concrete security treatment of several "provably secure" hash functions. Interpreting arguments behind MQ-HASH, FSB, SWIFFTX and VSH we identify similar lines of reasoning. We aim to formulate the main security claims in a language closer to t ...

Biometrics & [and] Security

Claude Barral

Since the beginning of this brand new century, and especially since the 2001 Sept 11 events in the U.S, several biometric technologies are considered mature enough to be a new tool for security. Generally associated to a personal device for privacy protect ...

Model Checking Detectability of Attacks in Multiagent Systems

Information security is vital to many multiagent system applications. In this paper we formalise the notion of detectability of attacks in a MAS setting and analyse its applicability. We introduce a taxonomy of detectability specifications expressed in tem ...

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 ...

Self-Organized Anonymous Authentication in Mobile Ad Hoc Networks

Jean-Pierre Hubaux, Julien Freudiger, Maxime Raya

Pervasive communications bring along new privacy challenges, fueled by the capability of mobile devices to communicate with, and thus "sniff on", each other directly. We design a new mechanism that aims at achieving location privacy in these forthcoming mo ...

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 ...

Security and Cooperation in Wireless Networks

Jean-Pierre Hubaux, Levente Buttyan

According to most technology pundits, progress in wireless and sensor networks will lead us into a world of ubiquitous computing, in which myriads of tiny, untethered sensors and actuators will communicate with each other. Information technology will thus ...

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 ...
