MAD-EN: Microarchitectural Attack Detection through System-wide Energy Consumption

1 code implementation31 May 2022 Debopriya Roy Dipta, Berk Gulmezoglu

Unfortunately, previous studies utilize hardware performance counters that lead to high performance overhead and profile limited number of microarchitectural attacks due to the small number of counters that can be profiled concurrently.
