Abstract
Elliptic curve cryptography on smart cards is vulnerable under a particular Side Channel Attack: the existence of zero-value points (ZVP). One approach to face this drawback relies on changing the curve for an isogenous one, until a resistant curve is found. This paper focuses on an alternative strategy: exploiting the properties of a recently introduced form of elliptic curves, Edwards curves. We show that these curves achieve conditions for being resistant to ZVP-attacks. Hence, using Edwards curves is a good countermeasure to avoid these attacks.
