The resistance of an FPGA implementation of Grasshopper block cipher to CPA attacks

10 Apr 2019  ·  Delaunay Cédric ·

In this paper, we implement the Russian standard block cipher Grasshopper on Field-Programmable Gate Array (FPGA). We also study the Correlation Power Analysis attack, which is a special type of side-channel attack proposed by Brier et al. To face this kind of attack, we propose a solution of software countermeasure, and we present the associated implementation of the Grasshopper algorithm... These two implementations are then compared to an AES-256 one. Finally, through the implementation of a CPA attack on an FPGA development board, we show that typical attack models that work on AES fail on Grasshopper implementations. read more
