Abstract
A computing device may use machine learning techniques to determine the level, degree, and severity of its vulnerability to side channel attacks. The computing device may intelligently and selectively perform obfuscation operations (e.g., operations to raise the noise floor) to prevent side channel attacks based on the determined level, degree, or severity of its current vulnerability to such attacks. The computing device may also monitor the current level of natural obfuscation produced by the device, determining whether there is sufficient natural obfuscation to prevent a side channel attack during an ongoing critical activity, and perform the obfuscation operation during the ongoing critical activity and in response to determining that there is not sufficient natural obfuscation to adequately protect the computing device against side channel attacks.
