Diese Festschrift zu Joseph Jurts 65. Geburtstag bündelt einen wichtigen Aspekt im Werk des Jubilars in einer konkreten Themenstellung. Intellektuelle Redlichkeit/intégrité intellectuelle wird von deutsch- und französischsprachigen Autoren unterschiedlicher Disziplinen - Literatur- und Sprachwissenschaftlern, Soziologen, Historikern, Politologen und Rechtswissenschaftlern - aus vielfältigen methodischen und thematischen Zugangsweisen beleuchtet. Die Herausgeber haben sich das dichte Netz wissenschaftlicher Kontakte Joseph Jurts zunutze gemacht, um dieses verborgene Zentrum seiner Arbeiten einer umfassenden und übergreifenden Darstellung zuzuführen. Die acht thematischen Sektionen sind so organisiert, dass der transdisziplinäre Projektcharakter auch innerhalb der einzelnen Sektionen gewahrt bleibt. Das vorliegende Ergebnis möge in seinem Facettenreichtum nicht zuletzt auch als Illustration für den Erkenntnisgewinn dienen, den die Grenzen überschreitende Offenheit von Joseph Jurts wissenschaftlichem Engagement befördert

International audience ; Law as integrity as a dworkinian theory is mainly a theory of legal argumentation.The judicial argumentation is controversial and not a theoretical demonstration. It aims at the discovery of one best legal answer as far as legal disagreements are not merely verbel but genuine disagreements: they are argumentatin around different conceptions of the same concept. But the proposition of one best legal answer never would have the consequence to stop the process or argumentation.

As the amount of personal data collected by governments, institutions and companies increase, centralized data suffer from privacy violations arising from negligence, abusive use, internal and external attacks. Therefore, we envision a radically different, fully decentralized vision of personal data managed within a Personal Data Server (PDS) where the data is let under the control of its owner. The PDS approach resorts to Secure Portable Token (SPT), a new device which combines the tamper resistance of a smart card microcontroller with the mass storage capacity of NAND Flash. The data will be stored, accessed and its access rights controlled using such devices. To support powerful PDS application requirements, a full-fledged DBMS engine is embedded in the device. In order to cope with the SPT's hardware constraints, new database techniques have been introduced, based on pure sequential data structures to store the raw data, and also indexes, buffers, transaction logs, etc. To reach high scalability limits, the data structures must timely be stratified, i.e., reorganized into more efficient (but still sequential) data structures. In this novel context, the current thesis addresses the security techniques required to take full benefits of such a decentralized vision. Indeed, only the microcontroller of the SPT is secured. The database stored on the NAND Flash linked to the controller by a bus, remains outside the security perimeter of the microcontroller. As such, it may still suffer from confidentiality and integrity attacks. Moreover, PDS also relies on external supporting servers to provide data durability, availability, or other global processing functionalities. In the study, we consider the supporting servers as Honest-but-Curious, i.e., they correctly provide the services that are expected from them (typically serve store, retrieve, and delete data requests), but they may try to breach the confidentiality of any data that is stored locally. Therefore, appropriate secure protocols must be devised to achieve ...
