Finally, a state-of-the-art version of CTIDH! That is, deterministic and a prime of 2048 bits. We introduce a new batching strategy we call "wombats", making dCTIDH five times faster than deterministic CSIDH. Surprisingly, it even beats "non-deterministic" CTIDH.

dCTIDH: Fast & Deterministic CTIDH
This paper presents dCTIDH, a CSIDH implementation that combines two recent developments into a novel state-of-the-art deterministic implementation. We combine the approach of deterministic variants o...
