Batching CSIDH Group Actions using AVX-512 [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2021 Commutative Supersingular Isogeny Diffie-Hellman (or CSIDH for short) is a recently-proposed post-quantum key establishment scheme that belongs to the family of isogeny-based cryptosystems.

Disorientation faults in CSIDH [PDF]
, 2023 We investigate a new class of fault-injection attacks against the CSIDH family of cryptographic group actions. Our disorientation attacks effectively flip the direction of some isogeny steps.

How to Construct CSIDH on Edwards Curves [PDF]
Finite Fields and Their Applications, 2020 CSIDH is an isogeny-based key exchange protocol proposed by Castryck, Lange, Martindale, Panny, and Renes in 2018. CSIDH is based on the ideal class group action on p-isomorphism classes of Montgomery curves. In order to calculate the class group action,

Optimizations and Practicality of High-Security CSIDH [PDF]
IACR Communications in CryptologyIn this work, we assess the real-world practicality of CSIDH, an isogeny-based non-interactive key exchange. We provide the first thorough assessment of the practicality of CSIDH in higher parameter sizes for conservative estimates of quantum

Stronger and Faster Side-Channel Protections for CSIDH [PDF]
, 2019 CSIDH is a recent quantum-resistant primitive based on the difficulty of finding isogeny paths between supersingular curves. Recently, two constant-time versions of CSIDH have been proposed: first by Meyer, Campos and Reith, and then by Onuki, Aikawa ...

Quantum Security Analysis of CSIDH [PDF]
, 2020 CSIDH is a recent proposal for post-quantum non-interactive key-exchange, presented at ASIACRYPT 2018. Based on supersingular elliptic curve isogenies, it is similar in design to a previous scheme by Couveignes, Rostovtsev and Stolbunov, but aims at an ...

A note on key control in CSIDH [PDF]
IACR Cryptol. ePrint Arch., 2022 In this short note we explore a particular behaviour of the CSIDH key exchange that leads to a very special form of (shared) key control via the use of the quadratic twists.

Low Memory Attacks on Small Key CSIDH [PDF]
, 2023 Despite recent breakthrough results in attacking SIDH, the CSIDH protocol remains a secure post-quantum key exchange protocol with appealing properties. However, for obtaining efficient CSIDH instantiations one has to resort to small secret keys. In this
