Technology and urban issues: What type of development is appropriate for cities of the South?

Jean-Claude Bolay, Abigaïl-Laure Sarah Irène Kern

This paper deals with technologies, catalysts for change, and their links to development. Indeed, particularly for developing and emerging countries, scientific and technological breakthroughs create wonderful opportunities, but they may also convey risks ...

Numerical study of the effect of confining stress on rock fragmentation by TBM cutters

Lijun Yin, Hongsu Ma

This paper investigates the effect of confining stress on rock fragmentation under TBM cutters by numerical simulation. Firstly, based on the characteristics of the force-penetration curve, the confining stress conditions for TBM tunneling are divided into ...

Pollution Attack Defense for Coding Based Sensor Storage

László Czap, Levente Buttyan

We present a novel information theoretic approach to make network coding based storage secure against pollution attacks in sensor networks. The approach is based on a new decoding algorithm which makes it possible to ﬁnd adversarial blocks using one more e ...

The Extended Access Control for Machine Readable Travel Documents

Rafik Chaabouni

Machine Readable travel documents have been rapidly put in place since 2004. The initial standard was made by the ICAO and it has been quickly followed by the Extended Access Control (EAC). In this presentation, we discuss about the evolution of these stan ...

The Role of Game Theory in Key Agreement Over a Public Channel

Michael Christoph Gastpar

In this work we study the problem of key agreement over a public noiseless channel when Alice, Bob and Charlie observe discrete memoryless sources of an unknown distribution. Alice and Bob want to agree on a key K-AB that is protected from Charlie. At the ...

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 ...

Signatures for Multisource Network Coding

László Czap

We consider the problem of securing inter-ﬂow network coding with multiple sources. We present a practical homomorphic signature scheme that makes possible to verify network coded packets composed of data originating from diﬀerent sources. The multi-source ...

Group Secret Key Generation over Broadcast Erasure Channels

Christina Fragouli, Suhas Diggavi, Mahdi Jafari Siavoshani, Uday Kiran Pulleti

We consider a group of m trusted nodes that aim to create a shared secret key K over a wireless channel in the presence an eavesdropper Eve. We assume an erasure broadcast channel from one of the honest nodes to the rest of them including Eve. All of the t ...

Distinguishing Distributions Using Chernoff Information

Serge Vaudenay, Pouyan Sepehrdad, Thomas Baignères

In this paper, we study the soundness amplification by repetition of cryptographic protocols. As a tool, we use the Chernoff Information. We specify the number of attempts or samples required to distinguish two distributions efficiently in various protocol ...

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 ...
