Abstract
A method and protocol for determining linear combinations of a first and second point for an elliptic curve cryptography scheme, including determining a first scalar multiplication of the first point with a first scalar, the first scalar multiplication including performing iteratively in relation to the value of the first scalar either one of: doubling of the first point in Jacobian projective coordinates; or mixed addition with the first point in affine coordinates; determining a combination point by adding the second point to the resultant of the first scalar multiplication; obtaining an affine coordinate representation of the combination point; determining a second scalar multiplication of the combination point with a second scalar, the second scalar multiplication including performing iteratively in relation to the value of the second scalar either one of: doubling of the combination point in Jacobian projective coordinates; or mixed addition with the combination point in affine coordinates.
