Welcome to the resource topic for 2023/1097

Title:
Quantum Money from Abelian Group Actions

Authors: Mark Zhandry

Abstract:

We give a candidate construction of public key quantum money, and even a strengthened version called quantum lightning, from abelian group actions, which can in turn be constructed from suitable isogenies over elliptic curves. We prove our scheme is secure under new but plausible assumptions on suitable group actions.
