summary: We propose several new methods to protect the scalar multiplication on an elliptic curve against differential analysis. The basic idea consists in transforming the curve through various random morphisms to provide a nondeterministic execution of the algorithm.
The solutions we suggest complement and improve the state-of-the-art, but also provide a practical toolbox of efficient countermeasures. These should suit most of the needs for protecting implementations of crypto-algorithms based on elliptic curves.
