CSIDH: Intro

WebMar 16, 2024 · Abstract. We present an optimized, constant-time software library for commutative supersingular isogeny Diffie-Hellman key exchange (CSIDH) proposed by Castryck et al. which targets 64-bit ARM processors. The proposed library is implemented based on highly-optimized field arithmetic operations and computes the entire key … WebThe isogeny-based scheme CSIDH is a promising candidate for quantum-resistant static-static key exchanges with very small public keys, but is inherently difficult to implement in …

WebJan 1, 2024 · Castryck, Lange, Martindale, Panny, and Renes [1] proposed another isogeny-based key-exchange protocol CSIDH (Commutative SIDH). CSIDH uses an action of an ideal class group on a set of classes of supersingular elliptic curves. Currently, many researches focus on the protocols using supersingular elliptic curves due to their efficiency.
