Shai Levin - Post Quantum Cryptography

This site serves as a repository for some of my projects. You can contact me via shai(at)science(dot)capetown or shai(dot)levin(at)auckland(dot)ac(dot)nz.

About Me

Raised in South Africa, living in New Zealand. Working on a PhD in Post Quantum Cryptography at University of Auckland in 2022 under Steven Galbraith. I love Muay Thai & Mathematics. My mathematical interests include number theory, combinatorics, algebraic graph theory.

Current Projects

Applying bleeding-edge generic Zero-Knowledge proof systems (such as zkSNARKs) to obtain faster and smaller post-quantum protocols.

Projects

An implementation of Supersingular Isogeny Key Exchange (SIKE) in Python.
Slides for a talk I've done on Expander Graphs in Cryptography.
My honours project with a summary of Elliptic Curves, their isogenies, and a way to construct lifts from isogeny graphs.
My slides for a 'thesis in three' on my honours project.
A report on an open problem of existence of particular Ramanujan graphs.
Some cyber security related reports I've done based on experiments on wireless network security, applications of VPNs and the vulnerability of cheap IoT devices.
I maintain this website.
