Abstract
Input signals may be received. Furthermore, a control signal controlling the implementation of a Differential Power Analysis (DPA) countermeasure may be received. One of the input signals may be transmitted as an output signal based on the control signal. A cryptographic operation may be performed based on the first output signal that is transmitted based on the control signal.
