Integrated all-digital low-dropout regulator as a countermeasure to power attack in encryption engines

Abstract

Low-drop-out (LDO) voltage regulator modules are being increasingly integrated in the modern processors for efficient power management. This paper shows that an integrated All-Digital LDO (ADLDO) can also be used as a countermeasure against power measurement based side channel attacks. The current transformation introduced by integrated digital LDOs… (More)
