Mean value formulas for twisted Edwards curves

Dustin Moody

Abstract: R. Feng, and H. Wu recently established a certain mean-value formula for the x-coordinates of the n-division points on an elliptic curve given in Weierstrass form (A mean value formula for elliptic curves, 2010, available at ). We prove a similar result for both the x and y-coordinates on a twisted Edwards elliptic curve.
