Software-Based Energy-Consumption Measurement for Side-Channel
Analysis.

This thesis examines the applicability of energy-consumption
measurement with software-based methods in the context of
side-channel analysis. A suitable software-based measurement
approach is leveraged to empirically show that four program
transformations for timing side-channel mitigation induce
energy-consumption over- head. We investigate the class of
energy-consumption side channels, show their presence in four
exemplary programs and quantify their severity using an
experimental approach. An evaluation of the positive effects of
program transformations on these side channels shows that some
transformations mitigate them quite effectively.
