| Important Note: The talk by Alex Fok has been moved to Tuesday 29th of October as Eamonn pointed out that next week we already have a talk in the morning and may have one in the afternoon by incoming job candidates In this talk, we will first introduce the Supersingular Isogeny Diffie-Hellman (SIDH) key exchange protocol and explain the most important underlying mathematical details. Then we will move on and exhibit some of its problems and pitfalls. As a remedy for those problems, the cryptographic community has proposed a modified protocol called k-SIDH. We will describe our attack against 2-SIDH and how well it scales for larger k. Next talks in the series: 22/10 Evgeny Vdovin: Baer Suzuki theorem for the Pi-radical 29/10 Alex Fok: Extended Verlinde algebra |
