摘要
Abstract
SPRING block cipher is an award-winning algorithm of the recent National Cryptographic Algorithm Design Competition in China in 2020.Truncated differential cryptanalysis is a cryptanalysis tool based on differential cryptanalysis,whose main idea is to study the impact of partial differences in the input on the output differences.This study exploits the properties of the SubRow transformation and matrix transposition transformation of the SPRING block cipher to construct a 5-round truncated differential characteristics for SPRING128-128.Then,a key recovery attack is performed on 7-round SPRING128-128,with the data complexity of 279 chosen plaintexts,the memory complexity of 244 bytes,and the time complexity of 2122 7-round SPRING128-128 encryptions,which is currently the best cryptanalysis result for SPRING128-128.关键词
