A Review of Research on Side-channel Signal Acquisition for Cryptographic Chip

Abstract

The side-channel attack includes signal acquisition, signal statistical analysis of the two parts. At home and abroad the current research on attacks mainly focuses on the side-channel statistical analysis method. However, the acquisition method of the leakage signal for the side-channel is lack of attention. Side-channel leakage signal acquisition is the premise to side-channel cryptanalysis. The acquisition of side-channel signal directly affects the quality of the results access of side-channel analysis. This paper talks the analysis of the research status of side-channel: "Attach importance to analysis, lose sight of collection," and summarizes the different existing methods of leak signal`s acquisition of side-channel, introduces traditional signal acquisition method of side-channel, the method of side-channel power signal acquisition, the method of electromagnetic signal acquisition and the method of how to collect side-channel time signal. Finally, this paper summarizes the introductive methods and prospects the acquisition method of side-channel signal.
