Transactions on Cryptographic Hardware and Embedded Systems, 2023 Strategies and their evaluations play important roles in speeding up the computation of large smooth-degree isogenies. The concept of optimal strategies for such computation was introduced by De Feo et al., and virtually all implementations of isogeny ...

A multi‐device user authentication mechanism for Internet of Things
IET Networks, Volume 12, Issue 5, Page 229-249, September 2023., 2023 The authors propose a secure user authentication mechanism supporting user access to an IoT environment from multiple devices. A novel One‐time Password (OTP) generation mechanism is presented to detect new device usage by a user. The integrity of the proposed scheme is affirmed using BAN logic, AVISPA tool, and informal security analysis. Besides, the

Secure post‐quantum group key exchange: Implementing a solution based on Kyber
IET Communications, Volume 17, Issue 6, Page 758-773, April 2023., 2023 In this article, the authors report on the implementation of a post‐quantum group key exchange protocol, which is proven secure in the so‐called Quantum Random Oracle Model. It is based on a two‐party design called Kyber, which is a finalist in the NIST standardization contest for post‐quantum cryptographic designs.

Practical isogeny-based cryptography
, 2021 This thesis aims at providing efficient and side-channel protected implementations of isogeny-based primitives, and at their application in threshold protocols. It is based on a sequence of academic papers. Chapter 3 reviews the original variable-time implementation of CSIDH and introduces several optimizations, e.g.

Highly Vectorized SIKE for AVX-512
Transactions on Cryptographic Hardware and Embedded Systems, 2022 It is generally accepted that a large-scale quantum computer would be capable to break any public-key cryptosystem used today, thereby posing a serious threat to the security of the Internet’s public-key infrastructure.

Constructing elliptic curve isogenies in quantum subexponential time
Journal of Mathematical Cryptology, 2014 Given two ordinary elliptic curves over a finite field having the same cardinality and endomorphism ring, it is known that the curves admit a nonzero isogeny between them, but finding such an isogeny is believed to be computationally difficult.
