CSI-IBBS: Identity-Based Blind Signature using CSIDH

open access: yes
Identity-based cryptography (IBC), proposed by Adi Shamir, revolutionized public key authentication by eliminating the need for certificates, enabling a more efficient and scalable approach to cryptographic systems. Meanwhile, in \cite{Katsumata2024group}, Katsumata et al.

DeCSIDH: Delegating isogeny computations in the CSIDH setting [PDF]

open access: yes
Delegating heavy computations to auxiliary servers, while keeping the inputs secret, presents a practical solution for computationally limited devices to use resource-intense cryptographic protocols, such as those based on isogenies, and thus allows the ...

CSIDH on the Surface [PDF]

open access: yesLecture Notes in Computer Science, 2020
For primes \(p \equiv 3 \bmod 4\), we show that setting up CSIDH on the surface, i.e., using supersingular elliptic curves with endomorphism ring \(Z[(1 + \sqrt{-p})/2]\), amounts to just a few sign switches in the underlying arithmetic. If \(p \equiv 7 \
