Abstract
A method includes receiving a first input value and a second input value, and obtaining a set of pre-computed values, wherein each pre-computed value is computed as the first input value multiplied by a given multiple in a set of multiples comprising powers of 2. A cryptographic process is performed to generate a cryptographic value based on the first and second input values, and one or more of the pre-computed values, wherein the cryptographic value that is generated is usable to generate a secure message or digital signature. The cryptographic process includes performing an iterative scalar multiplication process in which each step of the iterative scalar multiplication process is performed using a single point add operation to multiply a bit of the second input value with one of the pre-computed values in the set of pre-computed values.
