ABSTRACT:
An elliptic curve cryptosystem includes process to multiply a scalar value with an elliptic curve point. The processes provide a countermeasure against address-bit attacks. The processes have no correlation between the bit values of a scalar and the addresses of the operands of point addition and doubling operations and therefore provide countermeasures against power attacks.
