Group Signatures and Accountable Ring Signatures from Isogeny-based Assumptions [PDF]
, 2021 Group signatures are an important cryptographic primitive providing both anonymity and accountability to signatures. Accountable ring signatures combine features from both ring signatures and group signatures, and can be directly transformed to group ...

A Note on the Security of CSIDH
, 2018 We propose an algorithm for computing an isogeny between two elliptic curves $E_1,E_2$ defined over a finite field such that there is an imaginary quadratic order $\mathcal{O}$ satisfying $\mathcal{O}\simeq \operatorname{End}(E_i)$ for $i = 1,2$. This concerns ordinary curves and supersingular curves defined over $\mathbb{F}_p$ (the latter used in the ...

Design Automation ConferenceMulti-Precision Integer (MPI) arithmetic is a performance-critical component of many public-key cryptosystems, including besides classical ones (e.g., RSA, ECC) also isogeny-based post-quantum schemes.

Counting superspecial Richelot isogenies by reduced automorphism groups (Theory and Applications of Supersingular Curves and Supersingular Abelian Varieties) [PDF]
, 2022 The recent cryptanalysis by Costello and Smith [10] employed the subgraphs whose vertices consist of decomposed principally polarized abelian varieties, hence it is important to study the subgraphs in isogeny-based cryptography. Katsura and Takashima [22]

{KLaPoTi}: An asymptotically efficient isogeny group action from 2-dimensional isogenies [PDF]
We construct and implement an efficient post-quantum commutative cryptographic group action based on combining the SCALLOP framework for group actions from isogenies of oriented elliptic curves on one hand with the recent Clapoti method for polynomial ...

Isogenies and cryptography [PDF]
Cryptography is an essential tool for enabling privacy of electronic communication. However, many of the cryptographic protocols we use nowadays, would be insecure after the development of large-scale quantum computers.
