Au XIX-ieme siecle, Gauss avait remarqué que la moyenne arithmetico-géometrique (AGM) permet de calculer rapidement les integrales elliptiques . Nous montrerons comment un analogue p-adique fournit un algorithme efficace et simple à implémenter du calcul du nombre de points d'une courbe elliptique sur F_{2^n}, et nous decrirons un algorithme analogue dans le cas du genre 2.

    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[…]
