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…
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…
