Supersingular twisted Edwards curves over a simple field. II. supersingular twisted Edwards curves with an j-invariant equal to 663

Theorems on the conditions for the existence of supersingular Edwards curves over a prime field with the j-invariant equal to 663 and with other values of j-invariants are formulated and proved. A generalization of the results obtained earlier is presented, which uses isomorphisms of curves in Legendre and Edwards forms. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
