Single-Trace Attacks on Message Encoding in Lattice-Based KEMs

IEEE Access, 2020
In this article, we propose single-trace side-channel attacks against lattice-based key encapsulation mechanisms (KEMs) that are the third-round candidates of the national institute of standards and technology (NIST) standardization project. Specifically,

Secure Deployment of Smart Meters

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A secure initialization process for smart meters is designed based on a systematic cybersecurity risk analysis of the deployment phase. Three initialization variants are defined and compared with respect to security, operational feasibility, and trust distribution.

Algebraic approaches for solving isogeny problems of prime power degrees

Journal of Mathematical Cryptology, 2020
Recently, supersingular isogeny cryptosystems have received attention as a candidate of post-quantum cryptography (PQC). Their security relies on the hardness of solving isogeny problems over supersingular elliptic curves. The meet-in-the-middle approach

SIKE Channels

Transactions on Cryptographic Hardware and Embedded Systems, 2022
We present new side-channel attacks on SIKE, the isogeny-based candidate in the NIST PQC competition. Previous works had shown that SIKE is vulnerable to differential power analysis, and pointed to coordinate randomization as an effective countermeasure.

MA‐LCPPA: A Multi‐Aggregator Lattice‐Based Conditional Privacy‐Preserving Authentication Scheme for Scalable and Quantum‐Secure VANETs

IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.
This paper addresses the limitations of existing conditional privacy‐preserving authentication (CPPA) schemes in vehicular ad hoc networks (VANETs), which are either computationally heavy or vulnerable to quantum attacks. It proposes a multi‐aggregator lattice‐based CPPA (MA‐LCPPA) framework that distributes verification across multiple roadside units ...
