Power Analysis Masquerading and Obscuring
This countermeasure incorporates several tactics to obscure the power consumption patterns that could otherwise be exploited to infer sensitive key information. These methods focus on altering the detectable computational behaviour without affecting the integrity or outcome of the reconciliation process. These methods, for example, include: Randomizing Power Consumption, Dynamic Voltage and Frequency Scaling, Randomization of Syndrome Computation Order, Insertion of Dummy Operations.
