[Resource Topic] 2008/013: Twisted Edwards Curves

Welcome to the resource topic for 2008/013

Title:
Twisted Edwards Curves

Authors: Daniel J. Bernstein, Peter Birkner, Marc Joye, Tanja Lange, Christiane Peters

Abstract:

This paper introduces ``twisted Edwards curves,‘’ a generalization of the recently introduced Edwards curves; shows that twisted Edwards curves include more curves over finite fields, and in particular every elliptic curve in Montgomery form; shows how to cover even more curves via isogenies; presents fast explicit formulas for twisted Edwards curves in projective and inverted coordinates; and shows that twisted Edwards curves save time for many curves that were already expressible as Edwards curves.
