Abstract | ||
|---|---|---|
A side-channel attack (SCA) hardened AES-128 and RSA crypto-processor in 14-nm CMOS with measured resistance to correlation power/electromagnetic analysis (CPA/CEMA) in both time and frequency domains is demonstrated. While previously reported linear low-dropout regulators (LDOs) offer improvements in minimum-time-to-disclose (MTD) of extracted key bytes in the time domain, their transformations are less effective against frequency-domain attacks. This article describes a non-linear digital LDO (NL-DLDO) with control loop randomizations that bolster SCA resistance in the frequency domain. The NL-DLDO cascaded with an AES engine augmented with arithmetic countermeasures enables > 250K× improvement in MTD, with no CPA/CEMA/DNN attacks detected after 1-B encryptions, with 8% power and 10% area overheads incurred by arithmetic techniques. The RSA-4K crypto-processor implements exponent magnitude and timing randomizations along with dynamic memory addressing to mitigate time- and frequency-domain attacks. The countermeasures enable 711× suppression in means separation in current/EM magnitudes from 3.1 mV to 4.35 μV, reducing attacker's accuracy to an ineffective random guess classification, while limiting area and performance overheads to <; 0.05% and 3.25%, respectively. |
