These are some resources that I've compiled for my personal reference, either for research purposes or to look at in the future. I do not claim to have vetted each of these here. Any notes written are my own and should not be taken to be reflective of any of the authors. The presence (or absence) of a particular paper/resource has no meaning or intent prescribed.
Supersingular Isogeny Graphs in Cryptography Arizona Winter School 2026 (Kirsten Eisenträger, 2026)
These notes give an overview of isogeny-based cryptography, with a focus on the supersingular $\ell$-isogeny graph.
Mathematics of Isogeny-Based Cryptography (Luca de Feo, 2017)
Though outdated, these notes give an excellent overview of the field at large (at the time of 2017, when SIDH was still alive and well...)
