Webimpracticable. We focus on ECC scalar multiplication on so-called structured-order elliptic curves (very common in Elliptic Curves Cryptography). We assume that the attacker can observe several scalar multiplications with the same long-term secret scalar but each execution uses fresh randoms for scalar blinding. A
