针对ZUC算法硬件实现的相关能量攻击与多粒度时域敏感区域检测OA北大核心CSTPCD

This study decomposes modulo operations to implement the ZUC steam cipher algorithm in hardware environment and builds ZUC steam cipher energy consumption acquisition platform based on FPGA board.A detection method for sensitive area leaking of coarse-grained time-domain is constructed.The moving average operator is used to explore the risk area of high signal-to-noise ratio,the autocorrelation filter and peak detection operator are used to discover the operation interval with obvious repetitive characteristics and the high-risk leakage area is calibrated to achieve high-precision leakage risk location.Based on that,this paper proposes a CPA attack scheme based on the selection of initial vector to extract key information of the ZUC algorithm.By fixing some parts of plaintext,this paper implemented the scheme and successfully extracted the 8 bit key in the first round of algorithm initialization with only 3000 energy consumption traces,which shows the validity of the scheme.The pros and cons of the new implementation of the ZUC algorithm against side channel attack are discussed.
