Abstract

A method, system and elliptic curve cryptographic scheme for permitting secure communications between two or more cryptographic correspondent devices, the cryptographic scheme including a plurality of cryptographic operations applied to cryptographic parameters, the cryptographic operations including scalar multiplication of a point and a parameter, the elliptic curve cryptographic scheme characterized by selectively applying countermeasures and optimizations to the scalar multiplications by: applying a simple side-channel attack countermeasure for scalar multiplications that include a secret parameter as the parameter; applying a differential side-channel attack countermeasure for scalar multiplications when the elliptic curve point is not a generator point of the elliptic curve; and selectively applying optimizations.
