N2 - This paper examines the energy costs of different approaches to full disk encryption, including hardware encryption, software encryption, and "no encryption". Using the DEEP power measurement platform, we measured the energy consumed by each configuration under various workloads. We demonstrate that hardware encryption saves energy for many (though not all) workloads, but that the energy savings may not compensate for the hardware price at current rates.
