The double-and-add algorithm is a fundamental technique used to optimize the computation of scalar multiplication on an elliptic curve, which is a critical operation in Elliptic Curve Cryptography (ECC). Scalar multiplication involves computing , where is an integer (the scalar) and is a point on the elliptic curve. Direct computation of by repeated addition is
