Quaternion Algrebras and isogeny-based cryptography

, 2022
L'avènement de l'ordinateur quantique est une menace pour la cryptographie en permettant de résoudre les problèmes sur lesquels reposent la sécurité de nombreux protocoles. La cryptographie à base d'isogénies est une famille de protocoles reposant sur la difficulté de trouver une isogénie entre deux courbes elliptiques supersingulières, un problème ...

Isogeny-based post-quantum proxy signature for Internet of Things

Scientific Reports
The rapid growth of the Internet of Things (IoT) introduces challenges in secure authentication and delegation due to the limited computational capabilities of devices. Proxy signature schemes offer an effective solution by enabling controlled delegation

The design, concrete security and efficiency of isogeny-based cryptography [PDF]

The security of most public-key cryptosystems that are currently deployed rely on the hardness of the discrete logarithm problem or of the integer factorisation problem.

Key Policy Attribute-Based Encryption Leveraging Isogeny-Based Cryptography [PDF]

We present the first Key Policy Attribute-Based Encryption (KP-ABE) scheme employing isogeny-based cryptography through class group actions, specifically utilizing the Csi-FiSh instantiation and pairing groups. We introduce a new assumption, denoted Isog-

Hardware security of isogeny-based cryptography

Sécurisation matérielle de cryptographie post-quantique basée sur les isogénies entre courbes elliptiques En 1994, Shor a montré avec son algorithme de factorisation que les ordinateurs quantiques représentaient une menace pour la cryptographie asymétrique classique. Le National Institute of Standards and Technology (NIST) a alors lancé

Compressed Key Exchange Protocol from Orientations of Large Discriminant Using AVX-512

Transactions on Cryptographic Hardware and Embedded Systems
CSIDH (Commutative Supersingular Isogeny Diffie–Hellman) is a classgroup- based key-exchange protocol operated on supersingular elliptic curves, which, at the time of its proposal, exhibited several attractive selling points such as noninteractivity ...
