Description

  • Orateur

    Wouter Castryck - KU Leuven

I will report on some first attempts to do isogeny-based cryptography in genus 2. More precisely, we will use isogeny graphs of superspecial principally polarized abelian surfaces over GF(p^2) for constructing variants of Charles, Goren and Lauter's hash function and of Jao and De Feo's SIDH key exchange protocol, both of which use supersingular elliptic curves over GF(p^2). This will be largely based on joint work with Thomas Decru and Benjamin Smith.<br/> lien: http://desktop.visio.renater.fr/scopia?ID=722850***3761&autojoin
