Twisted edwards curves revisited

WebTwisted Edwards curves are parameterized by \(a, d\) and are of the form $$ \mathcal E_{a,d} : ax^2 + y^2 = 1 + dx^2y^2. $$ These are usually represented by the Extended Twisted Edwards Coordinates of Hisil, Wong, Carter, and Dawson: points are represented in projective coordinates as \((X:Y:Z:T)\) with $$ XY = ZT, \quad aX^2 + Y^2 = Z^2 + dT^2. $$ … WebDec 30, 2024 · 3.
