Csidh isogeny
WebSep 9, 2024 · CSIDH is an isogeny based primitive, similar to Diffie–Hellman, that can be used for key exchange and encapsulation [], signatures [4, 11, 14], and other more advanced protocols.Compared to the other main isogeny-based primitive SIDH [12, 17], CSIDH is slower.On the positive side, CSIDH has smaller public keys, is based on a … 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 …
