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. Webb1 juni 2024 · Extended optimization for Intel® IPP Cryptography SM4 (ECB, CBC, CFB, OFB, CRT) on 10th Generation Intel® Core™ processor family. Added new universal 16-bit CRC functions to compute CRC8, CRC16, CRC24 and CRC32 checksums. Enabled Intel® IPP Threading Layer for Intel® IPP Image Processing ippiCrossCorrNorm* functions.
