Description
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.

Polytopes in the Fiat-Shamir with Aborts Paradigm
Orateur : Hugo Beguinet - ENS Paris / Thales
The Fiat-Shamir with Aborts paradigm (FSwA) uses rejection sampling to remove a secret’s dependency on a given source distribution. Recent results revealed that unlike the uniform distribution in the hypercube, both the continuous Gaussian and the uniform distribution within the hypersphere minimise the rejection rate and the size of the proof of knowledge. However, in practice both these[…]-
