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 ...

Cooperative coding on orthogonal information networks

Dinkar Vasudevan

The focus of this thesis is on communication over cooperative information networks. In the first half of the thesis, we consider lossy source coding problems where a relay assists in the communication of a source stream between two terminals. The following ...

Neighborhood Gossip: Concurrent Averaging through Local Interference

Michael Christoph Gastpar

In this paper, we study a gossip algorithm for distributed averaging over a wireless sensor network. The usual assumption is that, through properly chosen codes, the physical layer is reduced to a set of reliable bit pipes for the distributed averaging alg ...

Temporally Consistent Layer Depth Ordering Via Pixel Voting For Pseudo 3D Representation

Engin Türetken

A new region-based depth ordering algorithm is proposed based on the segmented motion layers with affine motion models. Starting from an initial set of layers that are independently extracted for each frame of an input sequence, relative depth order of eve ...

Optimal Rate-Reliability-Delay Tradeoff in Networks with Composite Links

Suhas Diggavi

Networks need to accommodate diverse applications with different Quality-of-Service (QoS) requirements. New ideas at the physical layer are being developed for this purpose, such as diversity embedded coding, which is a technique that combines high rates w ...

Concurrent Transmissions in IR-UWB Networks: an Experimental Validation

Jean-Yves Le Boudec, Catherine Dehollain, Ruben Merz, Edmund James Colli-Vignarelli

We demonstrate and validate that concurrent and parallel transmissions are feasible for low data-rate impulse-radio ultrawide band (IR-UWB) physical layers. The optimal organization for a low data-rate IR-UWB network is to allow for concurrent transmission ...

Robustness to failures in two-layer communication networks

Maciej Kurant

A close look at many existing systems reveals their two- or multi-layer nature, where a number of coexisting networks interact and depend on each other. For instance, in the Internet, any application-level graph (such as a peer-to-peer network) is mapped o ...

Capacity of Deterministic Z-Chain Relay-Interference Network

Christina Fragouli, Suhas Diggavi

The wireless multiple-unicast problem is considered over a layered network, where the rates of transmission are limited by the relaying and interference effect. The deterministic model introduced in 131 is used to capture the broadcasting and multiple acce ...
