SIDE CHANNEL ANALYSIS SYSTEM AND SIDE CHANNEL ANALYSIS METHOD USING THE SAME

摘要

Disclosed are a side channel analysis system that may facilitate to perform side channel analysis on a device whose dedicated side channel analysis board does not exist such as a smartphone, and a side channel analysis method using the same. The side channel analysis system includes a side channel analysis device that outputs control signals for side channel analysis and performs side channel analysis based on received measurement signals, a device to be analyzed that performs generation and encryption function of optical signals for side channel measurement, according to the control signals provided from the side channel analysis device, an optical sensor module that detects the optical signals generated from the device to be analyzed, and generates and outputs trigger signals according to the detected optical signals, and a signal measurement device that measures waveforms of at least one signal generated according to an encryption operation of the device to be analyzed using the trigger signals output from the optical sensor module, and provides the measured waveforms to the side channel analysis device.
