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

SECURITY 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 ...

Isogeny-based Oblivious Transfer Protocols

, 2021
This thesis studies isogeny-based cryptography and its applications to oblivious transfer protocols. Isogeny crypto is based on difficult problems on the graph of isogenies between supersingular elliptic curves.

On extensions of the Jacobson–Morozov theorem to even characteristic

Journal 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 ...

Efficiency of SIDH-based signatures (yes, SIDH)

Journal of Mathematical Cryptology
In this note, we assess the efficiency of a supersingular isogeny Diffie-Hellman (SIDH)-based digital signature built on a weaker variant of a recent identification protocol proposed by Basso et al.

Compact, Efficient and UC-Secure Isogeny-Based Oblivious Transfer [PDF]

, 2022
Oblivious transfer (OT) is an essential cryptographic tool that can serve as a building block for almost all secure multiparty functionalities. The strongest security notion against malicious adversaries is universal composability (UC-secure).
