Pairing Optimizations for Isogeny-Based Cryptosystems
IET Information SecurityIn isogeny-based cryptography, bilinear pairings are regarded as a powerful tool in various applications, including key compression, public key validation, and torsion basis generation. However, in most isogeny-based protocols, the performance of pairing

Efficient Linkable Ring Signature Scheme over NTRU Lattice with Unconditional Anonymity. [PDF]
Comput Intell Neurosci, 2022 In cloud and edge computing, senders of data often want to be anonymous, while recipients of data always expect that the data come from a reliable sender and they are not redundant. Linkable ring signature (LRS) can not only protect the anonymity of the signer, but also detect whether two different signatures are signed by the same signer.

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.

An efficient post-quantum KEM from CSIDH
Journal of Mathematical Cryptology, 2022 The SIDH and CSIDH are now the two most well-known post-quantum key exchange protocols from the supersingular isogeny-based cryptography, which have attracted much attention in recent years and served as the building blocks of other supersingular isogeny-

Quantum algorithms for attacking hardness assumptions in classical and post‐quantum cryptography
IET Information Security, Volume 17, Issue 2, Page 171-209, March 2023., 2023 Abstract In this survey, the authors review the main quantum algorithms for solving the computational problems that serve as hardness assumptions for cryptosystem. To this end, the authors consider both the currently most widely used classically secure cryptosystems, and the most promising candidates for post‐quantum secure cryptosystems.

Lattice‐based cryptosystems in standardisation processes: A survey
IET Information Security, Volume 17, Issue 2, Page 227-243, March 2023., 2023 Abstract The current widely used public‐key cryptosystems are vulnerable to quantum attacks. To prepare for cybersecurity in the quantum era, some projects have been launched to call for post‐quantum alternatives. Due to solid security and desirable performance, lattice‐based cryptosystems are viewed as promising candidates in the upcoming ...

Optimized CSIDH Implementation Using a 2-Torsion Point
Cryptography, 2020 The implementation of isogeny-based cryptography mainly use Montgomery curves, as they offer fast elliptic curve arithmetic and isogeny computation. However, although Montgomery curves have efficient 3- and 4-isogeny formula, it becomes inefficient when ...

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 Postquantum Linkable Ring Signature Scheme from Coding Theory
Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 Linkable ring signatures (LRSs) are ring signatures with the extended property that a verifier can detect whether two messages were signed by the same ring member. LRSs play an important role in many application scenarios such as cryptocurrency and confidential transactions. The first code‐based LRS scheme was put forward in 2018.
