Abstract
A method of scalar multiplication to obtain the scalar product between a key and a point on an elliptic curve, wherein the secret is m bits long. In selected embodiments, the first step is to partition the secret into two partitions each with m/2 bits. Point-doubling operations are performed on the point and stored into three buffers. Point additions are performed at randomized time intervals thereby preventing the method from being susceptible to differential power analysis attacks.
