Abstract

When an ADC is converting a conﬁdential analog signal into digital codes, it may expose a critical hardware security loophole. By exploiting the strong correlation between the ADC digital output codes and the ADC supply current waveforms, an attacker can perform an ADC power side-channel attack (PSA) to steal the sensitive A/D conversion results by tapping into the power supply of the ADC. In this regard, this article demonstrates two neural-network-based successive approximation register (SAR)
