Description

    Frederik Vercauteren - Katholieke Universiteit Leuven

In the past 5 years there has been an explosion of applications of pairings. In this talk we will describe a recent construction of a variant of the Tate pairing which results in a significant speed-up. Furthermore, we will elaborate on the status of pairing inversion and its implications on pairing based cryptography, but also finite field cryptography.

    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[…]
