Research Data supporting: "The Security Risks of Power Measurements in Multicores"

To achieve these goals, hardware manufacturers and operating system providers include sophisticated power and performance management systems, which require detailed information about the current processor state.

For example, Intel processors offer the possibility to measure the power dissipation of the processor. In this work, we are evaluating whether such power measurements can be used to establish a covert channel between two isolated applications on the same system; the power covert channel. We present a detailed theoretical and experimental evaluation of the power covert channel on two platforms based on Intel processors.
