Stronger and Faster Side-Channel Protections for CSIDH
Daniel Cervantes-Vázquez, Mathilde Chenu, Jesús-Javier Chi-Domínguez +3
CSIDH is a recent quantum-resistant primitive based on the difficulty of finding isogeny paths between supersingular curves. Recently, two constant-time versions of CSIDH have been…
Standard Lattices of Compatibly Embedded Finite Fields
Luca De Feo, Hugues Randriam, Édouard Rousseau
Lattices of compatibly embedded finite fields are useful in computer algebra systems for managing many extensions of a finite field at once. They can also be used to…
Towards practical key exchange from ordinary isogeny graphs
Luca De Feo, Jean Kieffer, Benjamin Smith
We revisit the ordinary isogeny-graph based cryptosystems of Couveignes and Rostovtsev-Stolbunov, long dismissed as impractical. We give algorithmic improvements that accelerate ke…
Mathematics of Isogeny Based Cryptography
Luca De Feo
These lectures notes were written for a summer school on Mathematics for post-quantum cryptography in Thiès, Senegal. They try to provide a guide for Masters' students to get throu…
