DESCRIPTION:Speakers: Clémence Chevignard\n\nHawk is a signature publishe
 d in 2023\, whose security is based on a variant of the Lattice Isomorphis
 m Problem\, called  module-LIP. The publication of this signature sparked
  an interest in the resolution of module-LIP. In this talk\, we present a 
 polynomial time reduction from this problem\, to another mathematical prob
 lem that involves quaternion algebras. This result comes from a 2025 paper
  of ours\, that mainly uses number fields and quaternion algebras notions.
  If you want to learn more about it\, come to the talk.\n\nhttps://indico.
