Towards Isogeny-Based Password-Authenticated Key Establishment

Journal of Mathematical Cryptology, 2020
Password authenticated key establishment (PAKE) is a cryptographic primitive that allows two parties who share a low-entropy secret (a password) to securely establish cryptographic keys in the absence of public key infrastructure.

Hasse principle for Kummer varieties in the case of generic 2‐torsion

Proceedings of the London Mathematical Society, Volume 131, Issue 1, July 2025.
Abstract Conditional on finiteness of relevant Shafarevich–Tate groups, Harpaz and Skorobogatov used Swinnerton‐Dyer's descent‐fibration method to establish the Hasse principle for Kummer varieties associated to a 2‐covering of a principally polarised abelian variety under certain largeness assumptions on its mod 2 Galois image.

Towards quantum‐safe blockchain: Exploration of PQC and public‐key recovery on embedded systems

IET Blockchain, Volume 5, Issue 1, January/December 2025.
This paper addresses the need for quantum‐safe blockchain solutions specifically for embedded systems by integrating Post‐Quantum Cryptography (PQC) into blockchain frameworks. We propose a quantum‐secure blockchain architecture using NIST‐standardized PQC algorithms, finding Falcon‐512 to be optimal for embedded environments due to its security and ...

Exploring Post-Quantum Cryptography: Review and Directions for the Transition Process

Technologies
As quantum computing advances, current cryptographic protocols are increasingly vulnerable to quantum attacks, particularly those based on Public Key Infrastructure (PKI) like RSA or Elliptic Curve Cryptography (ECC).

Constructing Efficient Identity‐Based Signatures on Lattices

IET Information Security, Volume 2025, Issue 1, 2025.
In this work, we explore the recent developments related to lattice‐based signature and preimage sampling, and specify a compact identity‐based signature (IBS) on an ideal lattice for practical use. Specifically, we first propose an ellipsoid version of the G + G signature scheme (Asiacrypt 2023) that achieves slightly better signature size and higher ...

New Techniques for SIDH-based NIKE

Journal 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).

x2DL: A high throughput architecture for binary‐ring‐learning‐with‐error‐based post quantum cryptography schemes

IET Quantum Communication, Volume 5, Issue 4, Page 349-359, December 2024.
An efficient architecture for BRLWE‐based PQC schemes is proposed. It comprises a modified LFSR structure to obtain less latency and high throughput compared to the existing works. Due to reduction in latency, the performance metrics such as delay and area‐delay product (ADP) are also improved.

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

IEEE 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.

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 ...
