1. A method of obscuring software code implementing an elliptic curve cryptography (ECC) point multiplication function, comprising:

  • 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.
