Hidden Stabilizers, the Isogeny To Endomorphism Ring Problem and the Cryptanalysis of pSIDH

Mingjie Chen, Muhammad Imran, Gábor Ivanyos +3

The Isogeny to Endomorphism Ring Problem (IsERP) asks to compute the endomorphism ring of the codomain of an isogeny between supersingular curves in characteristic given only a…

SALSA: Attacking Lattice Cryptography with Transformers

Emily Wenger, Mingjie Chen, François Charton +1

Currently deployed public-key cryptosystems will be vulnerable to attacks by full-scale quantum computers. Consequently, "quantum resistant" cryptosystems are in high demand, and l…

Orientations and cycles in supersingular isogeny graphs

Sarah Arpin, Mingjie Chen, Kristin E. Lauter +3

The paper concerns several theoretical aspects of oriented supersingular -isogeny volcanoes and their relationship to closed walks in the supersingular -isogeny graph.…

Orienteering with one endomorphism

Sarah Arpin, Mingjie Chen, Kristin E. Lauter +3

In supersingular isogeny-based cryptography, the path-finding problem reduces to the endomorphism ring problem. Can path-finding be reduced to knowing just one endomorphism? It is…

Quadratic Chabauty for Atkin-Lehner Quotients of Modular Curves of Prime Level and Genus 4, 5, 6

Nikola Adžaga, Vishal Arul, Lea Beneish +4

We use the method of quadratic Chabauty on the quotients of modular curves by their Fricke involutions to provably compute all the rational points of these curv…
