The need for energy optimizations in modern systems forces CPU vendors to provide Dynamic Voltage Frequency Scaling (DVFS) interfaces that allow software to control the voltage and frequency of CPU cores. In recent years, the accessibility of such DVFS interfaces to adversaries has amounted to a plethora of fault attack vectors. In response, the current …
