Horizontal isogeny graphs of ordinary abelian varieties and the discrete logarithm problem [PDF]

open access: yes, 2017
Fix an ordinary abelian variety defined over a finite field. The ideal class group of its endomorphism ring acts freely on the set of isogenous varieties with same endomorphism ring, by complex multiplication.

New Techniques for SIDH-based NIKE

open access: yesJournal of Mathematical Cryptology, 2020
We consider the problem of producing an efficient, practical, quantum-resistant non-interactive key exchange (NIKE) protocol based on Supersingular Isogeny Diffie-Hellman (SIDH).

A survey analysis of quantum computing adoption and the paradigm of privacy engineering

open access: yesSECURITY AND PRIVACY, Volume 7, Issue 6, November/December 2024.
Abstract This study investigates the adoption of quantum computing (QC) technology using the diffusion of innovation (DOI) theory and provides an extensive literature review. We deployed structural equation modeling to analyze data from a survey conducted among 96 top managers in various industries from Canada, the US, and Europe, including IT‐based ...

On extensions of the Jacobson–Morozov theorem to even characteristic

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 5, November 2024.
Abstract Let G$G$ be a simple algebraic group over an algebraically closed field k$\mathbb {k}$ of characteristic 2. We consider analogues of the Jacobson–Morozov theorem in this setting. More precisely, we classify those nilpotent elements with a simple 3‐dimensional Lie overalgebra in g:=Lie(G)$\mathfrak {g}:=\operatorname{Lie}(G)$ and also those ...

Fast Large Integer Modular Addition in GF(p) Using Novel Attribute-Based Representation

open access: yesIEEE Access, 2019
Addition is an essential operation in all cryptographic algorithms. Higher levels of security require larger key sizes and this becomes a limiting factor in GF(p) using large integers because of the carry propagation problem.

On isogeny classes of Edwards curves over finite fields [PDF]

open access: yes, 2011
We count the number of isogeny classes of Edwards curves over finite fields, answering a question recently posed by Rezaeian and Shparlinski. We also show that each isogeny class contains a {\em complete} Edwards curve, and that an Edwards curve is ...

Hard isogeny problems over RSA moduli and groups with infeasible inversion [PDF]

open access: yes, 2019
We initiate the study of computational problems on elliptic curve isogeny graphs defined over RSA moduli. We conjecture that several variants of the neighbor-search problem over these graphs are hard, and provide a comprehensive list of cryptanalytic ...
