This paper shows that inductive integrated voltage regulators (IVR) provide significant immunity to traditional power attacks on crypto encryption engines based on timedomain analysis of the chip current. Frequency-domain analyses of envelope and duty cycle of the current are identified as new attack modes. The security-aware IVR design is discussed to provide additional immunity to power attack.
