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 pre-
viously 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 L
