  2. May 26, 2022Cryptography Reading Group - Dinesh Valluri

    Title: Faster Algorithms for Isogeny Problems using Torsion Point Images. 

    Speaker: Dinesh Valluri
    Affiliation: University of Waterloo
    Attend: Contact Jesse Elliott

    Abstract:

    In this talk, we will discuss cryptanalysis of some SIDH-type protocols due to Christophe Petit: https://eprint.iacr.org/2017/571.pdf. While finding isogenies between supersingular elliptic curves remains computationally hard to solve, knowledge of images of specific torsion points by the unknown isogeny helps build faster attacks.
