| Abstract(in English) | This paper presents an evaluation of security level on high-speed asynchronous successive approximation register (SAR) analog-to-digital converters. The SAR logic asynchronously controls the next comparison voltage of the following bits based on the current comparison result, which enhances the operation speed of SAR AD converters. However, the fatal feature is raised that the operation timing of the asynchronous logic depends on the input signal. Utilizing this characteristic, a side-channel attack on asynchronous SAR AD converters by analyzing the power noise and restoring the input data can be a serious threat. In this paper, we designed the high-speed asynchronous SAR AD converters in 40 nm CMOS to evaluate the side-channel leakage. To acquire the power supply noise waveform information in detail, an on-chip noise monitor circuits were also embedded on the same chip. The noise monitor circuits include a wide-band inputs to monitor the operating noise of high-speed asynchronous logic. From the evaluation results, we confirmed the timing information with a high correlation to the input signal exists on the operating power supply noise waveform of the asynchronous SAR ADC acquired by the on-chip noise monitor circuits. |
