Description
We will discuss a p-adic method to construct an elliptic curve over a finite field such that the group of rational points over the base field has some prescribed order N. The method uses ideas of Couveignes-Henocq, and is being developed and improved by my PhD student Reinier Broker.

Oblivious Transfer from Zero-Knowledge Proofs (or how to achieve round-optimal quantum Oblivious Transfer without structure)
Orateur : Léo Colisson - Université Grenoble Alpes
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[…]-
