Review of Chosen Isogeny-Based Cryptographic Schemes [PDF]

open access: goldCryptography, 2022
Public-key cryptography provides security for digital systems and communication. Traditional cryptographic solutions are constantly improved, e.g., to suppress brute-force attacks.

Torsion point attacks on ‘SIDH‐like’ cryptosystems

open access: yesIET Information Security, 2023
Isogeny‐based cryptography is a promising approach for post‐quantum cryptography. The best‐known protocol following that approach is the supersingular isogeny Diffie–Hellman protocol (SIDH); this protocol was turned into the CCA‐secure key encapsulation ...

Verifiable Delay Function and Its Blockchain-Related Application: A Survey [PDF]

open access: yesSensors, 2022
The concept of verifiable delay functions has received attention from researchers since it was first proposed in 2018. The applications of verifiable delay are also widespread in blockchain research, such as: computational timestamping, public random ...

Complete Analysis of Implementing Isogeny-Based Cryptography Using Huff Form of Elliptic Curves

open access: goldIEEE Access, 2021
In this paper, we present the analysis of Huff curves for implementing isogeny-based cryptography. In this regard, we first investigate the computational cost of the building blocks when compression functions are used for Huff curves.

Towards Green Computing Oriented Security: A Lightweight Postquantum Signature for IoE [PDF]

open access: yesSensors, 2021
Postquantum cryptography for elevating security against attacks by quantum computers in the Internet of Everything (IoE) is still in its infancy. Most postquantum based cryptosystems have longer keys and signature sizes and require more computations that

How to Compute an Isogeny on the Extended Jacobi Quartic Curves? [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2022
Computing isogenies between elliptic curves is a significant part of post-quantum cryptography with many practical applications (for example, in SIDH, SIKE, B-SIDH, or CSIDH algorithms).

Practical Usage of Radical Isogenies for CSIDH

open access: yesIEEE Access, 2023
Recently, a radical isogeny was proposed to boost commutative supersingular isogeny Diffie–Hellman (CSIDH) implementation. Radical isogenies reduce the generation of a kernel of a small prime order when implementing CSIDH.

SIKE Channels

open access: yesTransactions 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.
