Abstract
A method of obscuring software code implementing an elliptic curve cryptography (ECC) point multiplication function, including: receiving ECC parameters including a multiplier d having N bits; transforming multiplier d into an array d(i) with −1, 0, and +1 values while maintaining the same value for d; and generating ECC point multiplication function operations using the transformed multiplier array d(i) and N, wherein the generated ECC point multiplication function operations are split variable operations.
