SIKE is an isogeny-based key encapsulation suite based on pseudo-random walks in supersingular isogeny graphs, that was submitted to the NIST standardization process on post-quantum cryptography.

Supersingular isogeny Diffie–Hellman key exchange (SIDH or SIKE) was an insecure proposal for a post-quantum cryptographic algorithm to establish a secret key between two parties over an …

SIKE is a family of post-quantum key encapsulation mechanisms based on the Supersingular Isogeny Diffie-Hellman (SIDH) key exchange protocol. The algorithms use arithmetic operations on elliptic …

In this work, we study several post-quantum authenticated key exchange protocols in the setting of supersingular isogenies.

Sep 15, 2022 · Although there are no other active isogeny-based candidates participating in the NIST standardization process, we hope that research and development into isogeny-based cryptosystems …

We propose a new method for computing large-degree isogenies of an odd power. We provide explicit algorithms and formulas to speed up these large-degree isogenies. We implement, deploy, and …

Supersingular Isogeny Key Encapsulation (SIKE) is a post-quantum cryptography key encapsulation method for key exchange, and is based on Supersingular Isogeny Diffie-Hellman (SIDH). In this case …

Exploring alternative hard problems in isogeny-based cryptography, beyond the conventional Supersingular Isogeny Diffie–Hellman (SIDH) framework, may provide new foundations for secure …

Abstract—In this work, we present a fast and area-efficient software-hardware implementation of the supersingular isogeny key encapsulation (SIKE) mechanism. Our software-hardware design …

SIKE (Supersingular Isogeny Key Encapsulation) offers a promising solution for securing key exchanges in a post-quantum world. With its small key sizes and strong resistance to quantum attacks, SIKE is …
