Abstract
Two defense mechanisms, a hardware-based and software-based solution, are provided to protect a device during charging. The defenses randomly perturb the current drawn during charging thereby masking the unique patterns of the user's activities. It is shown that the two defenses force each one of the attacks to perform no better than random guessing, thus acting as effective defense mechanisms against all such types of attacks.
