Title: Improving Implementations of CSIDH

Abstract: 

I will present on some papers related to implementations of CSIDH [1]. In particular, I'll discuss methods to speed up evaluation of the class group action (e.g., permutations of the list of primes [2,3,4], Elligator [3], SIMBA [3], the two-point method [4]), parameter choices (the keyspace [3,4] and strategies), and constant-time implementations (using dummy isogenies [3]).
