Webpoint operations, is viable. DSCA can be thwarted by ensuring that the scalar multiplication algo-rithm processes strictly unpredictable, e.g. randomized, data. Typical random-ization techniques include base point blinding [20], randomized projective coor-dinates [20], curve isomorphisms [27] and ﬁeld isomorphisms [27]. Alternative WebNew power attack countermeasures for ECC over Koblitz curves are proposed, which randomize the involved elliptic curve points in a highly regular manner so the resulting scalar multiplication algorithms can defeat the simple power analysis attack and the differential powerAnalysis attack simultaneously.

Webattacks (DPA) in ECC have been proposed in [2,3], namely scalar blinding, scalar splitting and point blinding. All of these countermeasures either randomize the secret scalar or the base point of the curve. In this paper, we target all three of these countermeasures with an asynchronous granular sampling of branch
