26 Elliptic Curve An elliptic curve over a field K of characteristic other than 2 or 3 is the set of point (X, Y ) such that Y 2 = X 3 + AX + B where A, B K and 4A B 3 0, and a point at infinity 0 E. TYPES Workshop, june 2006 p. 7/22
27 Elliptic Curve An elliptic curve over a field K of characteristic other than 2 or 3 is the set of point (X, Y ) such that Y 2 = X 3 + AX + B where A, B K and 4A B 3 0, and a point at infinity 0 E. This is called the Weierstrass representation of the curve. TYPES Workshop, june 2006 p. 7/22
28 Elliptic Curve An elliptic curve over a field K of characteristic other than 2 or 3 is the set of point (X, Y ) such that Y 2 = X 3 + AX + B where A, B K and 4A B 3 0, and a point at infinity 0 E. This is called the Weierstrass representation of the curve. Switching to Montgomery and homogeneous form the equation of the curve becomes by 2 z = x 3 + ax 2 z + xz 2 which is more suited for computations. TYPES Workshop, june 2006 p. 7/22

35 Arithmetic on the curve A point on the curve is a triplet (x : y : z). We can forget y and identify P with P to get simpler formulas. To compute P + Q: x P+Q = 4z P Q (x P x Q z P z Q ) 2 z P+Q = 4x P Q (x P z Q z P x Q ) 2 so we need to have computed P Q already. Formulas for doubling omitted. TYPES Workshop, june 2006 p. 9/22
