WebbSM4 is a symmetric algorithm widely used in China, this patch enables to use SM4-XTS mode to encrypt file content, and use SM4-CBC-CTS to encrypt filename. WebbSM4 is a symmetric encryption algorithm, specifically a blockcipher, designed for data encryption. 1.1. Purpose This document does not aim to introduce a new algorithm, but to provide a clear and open description of the SM4 algorithm in English, and also to serve as a stable reference for IETF documents that utilize this algorithm. comfort items for pregnant women
龙蜥白皮书精选:基于 SM4 算法的文件加密(fscrypt)实践
Webbarm64架构上的国密优化最完整,效果也最明显,比如SM4算法,除了x86架构上的四个模式外,还对 CTS/XTS 模式,AEAD模式 CCM/GCM 以及带密钥的哈希算法做了深度优 … WebbBenchmark on T-Head Yitian-710 2.75 GHz, the data comes from the 218 mode of tcrypt, and compared the performance before and after this patch (the driver used before this patch is xts(ecb-sm4-ce)). The abscissas are blocks of different lengths. Webb4. Compute Structure The SM4 algorithm is a blockcipher, with block size of 128 bits and a key length of 128 bits. Both encryption and key expansion uses 32 rounds of a nonlinear … dr william abblitt
