In the context of attacking elliptic-curve scalar multiplication with template attacks, one can interleave template generation and template matching to reduce the amount of template traces. This paper enhances the power of this technique by defining and applying the concept of online template attacks (OTA); a general attack technique with minimal assumptions for an attacker, who has very limited control over the target device. We show that OTA need only one power consumption trace of a scalardoi:10.1007/978-3-319-13039-2_2 fatcat:ehl5e57csjfiblhxli5xzofvuu
