On correctness of conditions for the CSIDH algorithm implementation on Edwards curves

Radiotekhnika, 2022
Incorrect formulation and incorrect solution of the problem of the CSIDH algorithm implementation on Edwards curves  was revealed in one of the famous works. The purpose of this paper is to present a detailed critique of such concept with a proof of its inconsistency.

Patient Zero and Patient Six: Zero-Value and Correlation Attacks on CSIDH and SIKE [PDF]

, 2023
Recent works have started side-channel analysis on SIKE and show the vulnerability of isogeny-based systems to zero-value attacks. In this work, we expand on such attacks by analyzing the behavior of the zero curve $E_0$ and six curve $E_6$ in CSIDH and ...

POKEx: Performance Analysis of POKÉ-Key Exchange and SIDH-Variants

IEEE Access
In this paper, we present a comparative performance analysis of the POKÉ-based key exchange and SIDH variants. SIDH gained attention for its small key size and efficient performance, and has been selected as an alternate candidate in NIST PQC ...

Pairing Optimizations for Isogeny-Based Cryptosystems

IET 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

Efficient Constant-Time Implementation of terSIDH

IEEE Access
Since supersingular isogeny Diffie-Hellman (SIDH) was broken by a polynomial-time attack, several countermeasures were proposed as it was regarded as the most efficient algorithm among isogeny-based cryptosystems. Among them, terSIDH has been highlighted
