Towards quantum-resistant cryptosystems from supersingular elliptic curve isogenies
David Jao,Luca De Feo +1 more
TL;DR: In this article, the authors proposed a quantum-resistant public-key cryptosystem based on the conjectured difficulty of finding isogenies between supersingular elliptic curves, which allows the two parties to arrive at a common shared key despite the noncommutativity of the endomorphism ring.
Journal ArticleDOI
Towards quantum-resistant cryptosystems from supersingular elliptic curve isogenies
TL;DR: A new zero-knowledge identification scheme and detailed security proofs for the protocols, and a new, asymptotically faster, algorithm for key generation, a thorough study of its optimization, and new experimental data are presented.

Towards quantum-resistant cryptosystems from supersingular elliptic curve isogenies.
David Jao,Luca De Feo +1 more
TL;DR: In this paper, the authors proposed a quantum-resistant public-key cryptosystem based on the conjectured difficulty of finding isogenies between supersingular elliptic curves, where the main technical idea is that they transmit the images of torsion bases under the isogeny in order to allow the parties to construct a shared commutative square despite the noncommutativity of the endomorphism ring.
Book ChapterDOI
SQISign: Compact Post-quantum Signatures from Quaternions and Isogenies
TL;DR: A new signature scheme, SQISign, (for Short Quaternion and Isogeny Signature) from isogeny graphs of supersingular elliptic curves of known endomorphism rings is introduced, and it is proved that the resulting identification protocol is zero-knowledge.
Book ChapterDOI
Verifiable Delay Functions from Supersingular Isogenies and Pairings
TL;DR: Two new Verifiable Delay Functions (VDF) based on assumptions from elliptic curve cryptography are presented and their practicality is demonstrated with a proof-of-concept implementation.
