KLaPoTi: An asymptotically efficient isogeny group action from 2-dimensional isogenies

open access: yesIACR Communications in Cryptology
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 ...

Supersingular Isogeny Diffie-Hellman Key Exchange on 64-Bit ARM

IEEE Transactions on Dependable and Secure Computing, 2019
We present an efficient implementation of the supersingular isogeny Diffie-Hellman (SIDH) key exchange protocol on 64-bit ARMv8 processors for 125- and 160-bit post-quantum security levels.

Isoga: An Isogeny-Based Quantum-Resist Searchable Encryption Scheme Against Keyword Guessing Attacks

IEEE Systems Journal, 2023
Driven by cloud computing technologies, public-key encryption with keyword search (PEKS) is becoming a common practice from aspects of the Industrial Internet of Things, smart healthcare, vehicular social networks, and so on.

2-Adic Galois Images of Non-CM Isogeny-Torsion Graphs Defined over ℚ

Experimental Mathematics, 2023
Let E be a Q-isogeny class of elliptic curves defined over Q without CM. The isogeny graph associated to E is a graph which has a vertex for each elliptic curve in E and an edge for each Q-isogeny of prime degree that maps one elliptic curve in E to ...

Horizontal isogeny theorems

Forum Mathematicum, 2002
Summary: Let \(K\) be a field which is finitely generated over its prime field. Consider elliptic curves \(E\) and \(E'\) defined over \(K\). Suppose there exists \(c\geq 1\) and a set \(\Lambda\) of prime numbers such that \([K(E_l,E_l'): K(E_l)\cap K(E_l')]\leq c\) for all \(l\in\Lambda\).
