摘要：

To optimize ihe Software implementation of the domestic block cipher uBlock algorithm, the AVX2 Instruction set supporling 256 bil data widlh was implemented, ihe automatic optimization level of the Compiler was increased, optimizing the ealling process of functions, and the methods of data storage structure optimization, high-level parallelism and low laleney inslruction logie optimization were used in order to implemenl parallel Computing under the single-lhread condition. Using this efficient combination method, the speed of single key short message encryption of uBloek-128/128 algorithm, uBloek-128/256 algorithm and uBlock-256/256 algorithm are 269%, 182% and 49% higher lhan the original code. Based on these optimization methods, the implementation of single-key scenario and multi-key scenario are given for three algorithm versions of uBloek-128/128, uBlock-128/256 and uBlock-256/256. © 2024 National University of Defense Technology.
