Group Signatures Á la carte
نویسندگان
چکیده
A group signature scheme allows any member of a potentially large group to sign on behalf of the group. Group signatures are anonymous and unlinkable. Only a designated group manager can co-relate signatures and/or reveal the identity of the actual signer. At the same time, no one (including a group manager) can misattribute a valid signature. In this paper we construct a very eecient and provably secure group signature scheme.

SQL á la Carte - Toward Tailor-made Data Management
The size of the structured query language (SQL) continuously increases. Extensions of SQL for special domains like stream processing or sensor networks come with own extensions, more or less unrelated to the standard. In general, underlying DBMS support only a subset of SQL plus vendor specific extensions. In this paper, we analyze application domains where special SQL dialects are needed or ar...
متن کاملBundling, product choice, and efficiency: Should cable television networks be offered à la carte?
We conduct a numerical analysis of bundling’s impact on a monopolist’s pricing and product choices and assess the implications for consumer welfare in cable television markets. Existing theory is ambiguous: for a given set of products, bundling likely transfers surplus from consumers to firms but also encourages products to be offered that might not be under à la carte pricing. Simulation of ‘‘...
متن کاملLa carte GHSOM comme alternative à la SOM pour l'analyse exploratoire de données
Résumé. L’objecif de cet article est de faire de la carte auto-organisatrice hiérarchique (GHSOM) un outil utilisable dans le cadre d’une démarche d’analyse exploratoire de données. La visualisation globale est un outil indispensable pour rendre les résultats d’une segmentation intelligibles pour un utilisateur. Nous proposons donc différents outils de visualisation pour la GHSOM équivalents à ...
متن کاملSegmentation hiérarchique des cartes topologiques
Résumé. Dans ce papier, nous présentons une nouvelle mesure de similarité pour la classification des référents de la carte auto-organisatrice qui sera réalisée à l’aide d’une nouvelle approche de classification hiérarchique. (1) La mesure de similarité est composée de deux termes : la distance de Ward pondérée et la distance euclidienne pondérée par la fonction de voisinage sur la carte topolog...
متن کاملRadiative transfer limit of two-frequency Wigner distribution for random parabolic waves: An exact solution
The present Note establishes the self-averaging, radiative transfer limit for the two-frequency Wigner distribution for classical waves in random media. Depending on the ratio of the wavelength to the correlation length the limiting equation is either a Boltzmann-like integral equation or a Fokker–Planck-like differential equation in the phase space. The limiting equation is used to estimate th...
