Pairing Optimizations for Isogeny-Based Cryptosystems [PDF]

open access: yesIET Information Security
In 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

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 ...

Efficient Finite Field Multiplication for Isogeny Based Post Quantum Cryptography [PDF]

open access: yes, 2016
Isogeny based post-quantum cryptography is one of the most recent addition to the family of quantum resistant cryptosystems. In this paper we propose an efficient modular multiplication algorithm for primes of the form \(p=2\cdot {2^a}3^b-1\) with b even, typically used in such cryptosystem.

Finding Practical Parameters for Isogeny-based Cryptography [PDF]

open access: yesIACR Communications in Cryptology
Isogeny-based schemes often come with special requirements on the field of definition of the involved elliptic curves. For instance, the efficiency of SQIsign, a promising candidate in the NIST signature standardisation process, requires a large power of two and a large smooth integer

An Algorithmic Approach to (2, 2)-Isogenies in the Theta Model and Applications to Isogeny-Based Cryptography [PDF]

open access: yes
In this paper, we describe an algorithm to compute chains of (2, 2)-isogenies between products of elliptic curves in the theta model. The description of the algorithm is split into various subroutines to allow for a precise field operation counting. We present a constant time implementation of our algorithm in Rust and an alternative implementation in ...

Arithmetic Considerations for Isogeny-Based Cryptography [PDF]

open access: yesIEEE Transactions on Computers, 2019
In this paper we investigate various arithmetic techniques which can be used to potentially enhance the performance in the supersingular isogeny Diffie-Hellman (SIDH) key-exchange protocol which is one of the more recent contenders in the post-quantum public-key arena.

An efficient post-quantum KEM from CSIDH

open access: yesJournal 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-

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.
