Optimized Constant-Time Implementation of terSIDH [PDF]
Since supersingular isogeny Diffie-Hellman (SIDH) was broken by a polynomial-time attack, several countermeasures were proposed. Among them, terSIDH has been highlighted for its high performance, yet it exposes a side-channel vulnerability.

Zero-Knowledge Proofs for SIDH variants with Masked Degree or Torsion [PDF]
The polynomial attacks on SIDH by Castryck, Decru, Maino, Martindale and Robert have shown that, while the general isogeny problem is still considered unfeasible to break, it is possible to efficiently compute a secret isogeny when given its degree and ...

Towards Optimally Small Smoothness Bounds for Cryptographic-Sized Twin Smooth Integers and its Isogeny-based Applications [PDF]
, 2023 We give a new approach for finding large twin smooth integers. Those twins whose sum is a prime are of interest in the parameter setup of certain isogeny-based cryptosystems such as SQISign. The approach to find such twins is to find two polynomials in $\

INKE: Fast Isogeny-Based PKE using Intermediate Curves [PDF]
POKÉ (Point-Based Key Exchange), proposed by Basso and Maino in Eurocrypt 2025, is currently the fastest known isogeny-based public key encryption scheme, combining a SIDH-like protocol with higher-dimensional isogenies.

New Hybrid Method for Isogeny-based Cryptosystems using Edwards Curves [PDF]
, 2019 Along with the resistance against quantum computers, isogeny-based cryptography offers attractive cryptosystems due to small key sizes and compatibility with the current elliptic curve primitives. While the state-of-the-art implementation uses Montgomery

POKE: A Framework for Efficient PKEs, Split KEMs, and OPRFs from Higher-dimensional Isogenies [PDF]
We introduce a new framework, POKE, to build cryptographic protocols from irrational isogenies using higher-dimensional representations. The framework enables two parties to manipulate higher-dimensional representations of isogenies to efficiently ...

Optimized Method for Computing Odd-Degree Isogenies on Edwards Curves [PDF]
, 2019 In this paper, we present an efficient method to compute arbitrary odd-degree isogenies on Edwards curves. By using the $w$-coordinate, we optimized the isogeny formula on Edwards curves by Moody and Shumow.
