Description

  • Speaker

    René Schoof - Universita Roma 2

L'exposé portera sur la méthode trouvée il y a une quinzaine années par le conférencier pour calculer le nombre de points rationnels d'une courbe elliptique sur un corps fini. Il évoquera aussi les développements postérieurs (Atkin, Elkies, Satoh, Kedlaya, Mestre,...).

    We provide a generic construction to turn any classical Zero-Knowledge (ZK) protocol into a composable oblivious transfer (OT) protocol (the protocol itself involving quantum interactions), mostly lifting the round-complexity properties and security guarantees (plain-model/statistical security/unstructured functions…) of the ZK protocol to the resulting OT protocol. Such a construction is unlikely[…]
