Title: Elliptic Nets over the Edwards Model of Elliptic Curves
Date: November 23, 2021 Abstract: see below
Abstract
An elliptic net is a map defined from a free finitely-generated abelian group A to an integral domain R that satisfies a certain non-linear recurrence relation. In this work, we propose elliptic nets of rank 1 called elliptic divisibility sequences on the Edwards model of elliptic curves. We then derive the elliptic nets in that Edwards model of elliptic curves. Finally, we give the properties of that elliptic and particularly in rank 2 for further optimisation in the pairing computation based cryptography.
Keywords: Elliptic Divisibility Sequence, Elliptic nets, Division polynomial, Edwards Curves

Title: On the failure of the smart approach of the GPT cryptosystem
Date: November 2, 2021 Abstract: see below Slides: link
In this talk, we will talk a bit about the GPT cryptosystem (which is a rank-metric based cryptosystem) and its security. More precisely, we will present a new algorithm for breaking the smart approach of the GPT cryptosystem. We show that by puncturing the public code several times on specific positions, we get a public code on which applying the Frobenius operator appropriately allows to build an alternative secret key in polynomial time.
