Au Grand-Duché de Luxembourg, l’Association des Cercles d’Etudiants Luxembourgeois (ACEL) représente actuellement l’un des grands acteurs dans le domaine de l’information sur les transitions entre l’enseignement secondaire et l’enseignement supérieur, d’un côté, et entre l’enseignement supérieur et la vie professionnelle, de l’autre côté. Les campagnes d’information de l’ACEL se basent essentiellement sur ses différentes publications, qui sont mises gratuitement à disposition au public et élaborées en étroite collaboration avec ses cercles-membres et une série de partenaires et collaborateurs du secteur privé et public. Le but est d’informer le plus complètement possible sur toutes les étapes d’une formation supérieure, en commençant par les informations relatives au choix de la branche et du lieu d’étude, suivi par l’accompagnement et l’encadrement pendant les études elles-mêmes et allant jusqu’au passage à la vie professionnelle. Dans le présent travail, nous allons présenter l’ensemble des publications et actions de l’ACEL visant à faciliter ces deux transitions. [less ▲]

Publishing Community-Preserving Attributed Social Graphs with a Differential Privacy Guarantee

We present a novel method for publishing differentially private synthetic attributed graphs. Our method allows, for the first time, to publish synthetic graphs simultaneously preserving structural properties, user attributes and the community structure of the original graph. Our proposal relies on CAGM, a new community-preserving generative model for attributed graphs. We equip CAGM with efficient methods for attributed graph sampling and parameter estimation. For the latter, we introduce differentially private computation methods, which allow us to release communitypreserving synthetic attributed social graphs with a strong formal privacy guarantee. Through comprehensive experiments, we show that our new model outperforms its most relevant counterparts in synthesising differentially private attributed social graphs that preserve the community structure of the original graph, as well as degree sequences and clustering coefficients.

Zwischen 1819 und 1824 hatte Johann Heinrich Pestalozzi im Stuttgarter Verlag Cotta eine zwölfbändige Gesamtausgabe veröffentlicht. Diese wurde durch eine Subskription finanziert, wofür zuerst potenzielle Käuferinnen und Käufer geworben wer-den mussten. Der folgende Artikel untersucht mit einer Netzwerkperspektive, wie Pestalozzi bzw. seine Mitarbeiter dieses Projekt umgesetzt haben und wie die verschiedenen Netzwerke, die entscheidend zum Erfolg der Subskription beigetragen haben, zustande gekommen sind.

PUF-based authentication protocol to address ticket-switching of RFID-tagged items

in Proc. 8th Workshop on Security and Trust Management, Pisa, Italy, September 13-14 2012 (2015)

Ticket-switching incidents where customers switch the price tag or bar code in order to pay a lower amount for their ‘purchased item’ is not uncommon in retail stores. Since the item has to pass through a ... [more ▼]

Ticket-switching incidents where customers switch the price tag or bar code in order to pay a lower amount for their ‘purchased item’ is not uncommon in retail stores. Since the item has to pass through a check-out counter before leaving the store, it has a (even if miniscule) positive probability of being identified. However, when item-level RFID tags are used in an automated check-out environment, the probability of such incidents coming to light is estimated to be almost zero. We propose an authentication protocol for this scenario using a pair of item-level RFID tags, one of which is PUF-enabled to resist cloning attacks. [less ▲]

PUMConf: A Tool to Configure Product Specific Use Case and Domain Models in a Product Line

We present PUMConf, a tool for supporting configuration that currently focuses on requirements and enables effective product line management in the context of use case-driven development. By design, it relies exclusively on variability modeling for artifacts that are commonly used in such contexts (i.e., use case diagram, specifications and domain model). For given Product Line (PL) use case and domain models, PUMConf checks the consistency of the models, interactively receives configuration decisions from analysts, automatically checks decision consistency, and generates Product Specific (PS) use case and domain models from the PL models and decisions. It has been evaluated on an industrial case study in the automotive domain. [less ▲]
