Csidh isogeny
WebSIKE的全称为Supersingular Isogeny Key Encapsulation。 这是一种利用椭圆曲线作为定理的加密算法，看上去可以由一个y²=x³+Ax+B来表述，其中A和B是数字。 该方法的关键之处是使用了同源（Isogenies），也就是把一条椭圆曲线的点映射到另一条椭圆曲线上。 WebMar 23, 2024 · 2024. TLDR. This paper presents a concrete computational analysis of these novel procedures along with several algorithmic tricks that helped to further decrease its computational cost and reports an optimized Python3-code implementation of several instantiations of two isogeny-based key-exchange protocols, namely, CSIDH and B …

WebSupersingular isogeny Diffie–Hellman key exchange (SIDH or SIKE) is an insecure proposal for a post-quantum cryptographic algorithm to establish a secret key between two parties over an untrusted communications channel. It is analogous to the Diffie–Hellman key exchange, but is based on walks in a supersingular isogeny graph and was designed to … WebApr 10, 2024 · However, for obtaining efficient CSIDH instantiations one has to resort to small secret keys. In this work, we provide novel methods to analyze small key CSIDH, thereby introducing the representation method ---that has been successfully applied for attacking small secret keys in code- and lattice-based schemes--- also to the isogeny …
WebIsogeny-based cryptography is a kind of post-quantum cryptography whose security relies on the hardness of an isogeny problem over elliptic curves. In this paper, we study CSIDH, which is one of isogeny-based cryptography presented by Castryck et al. in Asiacrypt 2024. In CSIDH, the secret key is taken from an L∞-norm ball of integer vectors ...
