Supersingular Isogeny Diffie-Hellman

Supersingular Isogeny Diffie-Hellman is a cryptographic key exchange protocol intended to be resistent to attacks from quantum computers.

My work in this area includes:
  • My talk on SIDH on Youtube, with slides. Given at the University of Waterloo on July 12, 2016.
  • A library for compressing and decompressing SIDH keys. This work led to a joint collaboration and was accepted to Eurocrypt 2017.
  • Hand-optimized ARM64 assembler for SIDH finite field arithmetic (coming soon), including a working optimized key exchange.
  • My friendly introduction to Supersingular Isogeny Diffie-Hellman.

This is a list of articles I have written on various miscellaneous topics, usually with the aim of presenting an original perspective on existing work. Given in reverse chronological order.
