Side channel analysis is the process of examining information leaked by a computing device during use, and leveraging such data to make inferences about various aspects of the system. Historically, side channels have been exploited for malicious purposes, from inferring sensitive data to infringing on the privacy of users. For example, power consumption has been exploited to reveal secret cryptographic keys, and features of wireless network traffic have been leveraged to reveal web browsing activity of a user. The goal of this dissertation is not only to explore the potential of using side channels to determine what types of activity a computing system is engaged in but also study the relationship between the operations performed by the system and the side channel.
