Key Compression for Isogeny-Based Cryptosystems
Leonardi, Christopher (University of Waterloo, 2016-04-21)We present a method for key compression in quantum-resistant isogeny-based cryptosystems, which reduces storage and transmission costs of per-party public information by a factor of two, with no effect on the security level ... -
Security Analysis of Isogeny-Based Cryptosystems
Leonardi, Christopher (University of Waterloo, 2020-08-20)Let $E$ be a supersingular elliptic curve over a finite field. In this document we study public-key encryption schemes which use non-constant rational maps from $E$. The purpose of this study is to determine if such ...
