Abstract
We close this gap with KeyDrown, a new defense mechanism against software-based keystroke timing attacks. KeyDrown injects a large number of fake keystrokes in the kernel, making the keystroke interrupt density uniform over time, i.e., independent of the real keystrokes. All keystrokes, including fake keystrokes, are carefully propagated through the shared library to make them indistinguishable by exploiting the specific properties of software-based side channels. We show that attackers cannot distinguish fake keystrokes from real keystrokes anymore and we evaluate KeyDrown on a commodity notebook as well as on Android smartphones. We show that KeyDrown eliminates any advantage an attacker can gain from using software-based side-channel attacks.
