Dear editor,rnThe SM3 cryptographic hash algorithm[1]was approved as the only standard hash function in China and stan-dardized as a Chinese National Standard (GB standard) in 2016.Soon after,SM3 was standardized by the Interna-tional Organization for Standardization (ISO).The struc-ture of SM3 is similar to SHA-2 family[2],which based on the Merkle-Damg(a)rd construction,with the addition of sev-eral strengthening features including a more complex step function and stronger message dependency than SHA-2.
