Notations Throughout this chapter we use the same notations as above (see Sect. 2.​1). Recall that, during an attack, we consider that the adversary targets the manipulation of a single sensitive variable Z, such that . Typically , such that denotes a substitution box and denotes the bitwise addition. The attack is carried out with N traces , ..., . Each corresponds to the processing of . The number of samples per traces (instantaneous leakage points) is denoted by D.
