Abstract—Hardware encryption engines are essential com-
ponents of secure systems. They are widely used in desktop
applications such as the Trusted Platform Module as well as
in mobile applications where they offer high energy efficiency
compared to their software implementation counterparts. Unfor-
tunately, ASIC encryption engines leak side-channel information
through their power supplies. This information can be used by
attackers to reveal their secret keys with attacks such as
