摘　　要：SM3 is the Chinese hash standard and is standardized in GB/T 32905-2016 . As a hash function, it must fulfill three security requirements, colli-sion resistance, preimage resistance, and second preimage resistance. During the ongoing evahla- tion, it is believed that whenever the hash function behaves diffbrently from a random function,SM3 is the Chinese hash standard and is standardized in GB/T 32905-2016 .
