WebFLOR-SIDH-x64. This software library contains C-language + optimized x86_64 assembly code for implementing the Super-Singular Isogeny Diffie-Hellman algorithm proposed by Jao, De Feo and Plût. The code base is forked from the PQCrypto-SIDH project of Microsoft introduced by Costelo, Longa and Naehrig on CRYPTO 2016. WebSep 17, 2024 · The size of public keys is only 564 bytes, which is significantly smaller than most of the popular post-quantum key exchange alternatives. Ultimately, the size and speed of our software illustrates the strong potential of SIDH as a post-quantum key exchange …

WebAbstract: Since its introduction by Jao and De Feo in 2011, the supersingular isogeny Diffie-Hellman (SIDH) key exchange protocol has positioned itself as a promising candidate for post-quantum cryptography. One salient feature of the SIDH protocol is that it requires … WebFeb 28, 2024 · sidh. Project provides a Go implementation of (ephemeral) supersingular isogeny Diffie-Hellman (SIDH) and supersingular isogeny key exchange (SIKE), as specified in SIDH-spec, PQC NIST Submission (Nov 30, 2024).. Portions of the field arithmetic were ported from the Microsoft Research implementation. phil harvard university

Efficient Loop Abort Fault Attacks on Supersingular

WebJul 2, 2024 · SIKE stands for Supersingular Isogeny Key Encapsulation. SIKE.KEM is a Key Encapsulation Mechanism. A key encapsulation differs from a key exchange in a subtly technical way; think of it as a key exchange with a long term public key. SIDH is to SIKE as ECDH is to (the public key part of) ECIES. – Luca De Feo. A large-scale quantum computer breaks most public-key cryptography that is currently used on the internet such as RSA encryption and digital signatures, ECDH key exchange and ECDSA signatures. Even if no such quantum computer exists today, the prospect of one being built in the not-too-distant future … See more The supersingular isogeny Diffie-Hellman key exchange protocol was proposed by Jao and DeFeo in .
