Impact of inductive integrated voltage regulator on the power attack vulnerability of encryption engines: A simulation study

摘要

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.
