Computer Aided Cryptanalysis from Ciphers to Side Channels

Martin Vuagnoux

In this dissertation, we study the security of cryptographic protocols and cryptosystems from the mathematical definition of the primitives, up to their physical implementations in the real world. We propose a representation of the chronological design usi ...

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 ...

Model-based implementation of real-time applications

Joseph Sifakis

Correct and efficient implementation of general real-time applications remains by far an open problem. A key issue is meeting timing constraints whose satisfaction depends on features of the execution platform, in particular its speed. Existing rigorous im ...

Modelling Complex Fenestration Systems using physical and virtual models

Jean-Louis Scartezzini, Anothai Thanachareonkit

Physical or virtual models are commonly used to visualize the conceptual ideas of architects, lighting designers and researchers; they are also employed to assess the daylighting performance of buildings, particularly in cases where Complex Fenestration Sy ...

Brief Bursts Self-Inhibit and Correlate the Pyramidal Network

Henry Markram, Rodrigo de Campos Perin, Thomas Berger, Gilad Silberberg

Inhibitory pathways are an essential component in the function of the neocortical microcircuitry. Despite the relatively small fraction of inhibitory neurons in the neocortex, these neurons are strongly activated due to their high connectivity rate and the ...

Complémentarité de la modélisation physique et numérique à l’exemple d’un aménagement hydroélectrique / Complementarity of physical and numerical modeling using the example of a run-of-river hydropower plant

Martin Peter Bieri, Michael Müller

Comme beaucoup d’aménagements hydroélectriques au fil de l’eau, celui de Lavey sur le Rhône en Suisse est affecté de manière récurrente par l’alluvionnement de sa retenue. Outre la gestion sédimentaire, les thèmes abordés par la modélisation concernent éga ...

Authentication of documents and articles by moire patterns

Roger Hersch, Sylvain Chosson

The present invention relies on the moiré patterns generated when superposing a base layer made of base band patterns and a revealing line grating (revealing layer). The produced moiré patterns comprise an enlargement and a transformation of the individual ...
