The correct expression of sm3 is as follows:

In the computer field, SM3 is a commonly used hash algorithm, whose main purpose is to ensure the security of data, especially in digital signature and message digest. SM3 algorithm is a cryptographic algorithm designed by the National Cryptography Administration, and its security has been internationally recognized.

The security of SM3 hash algorithm has been widely recognized. Because SM3 uses a combination of symmetric encryption and asymmetric encryption, it has very high security. The design of SM3 algorithm is based on SHA-256 algorithm, and a series of improvements have been made to make it able to resist the strongest attacks at present, such as collision attacks and pre-mapping attacks.

SM3 algorithm shows high efficiency and reliability in practical application, and is widely used in various network communication scenarios. From the practical application, SM3' s statement is very correct.

SM3 algorithm is widely used in digital signature and message digest. Digital signature refers to the technology used to ensure data integrity, authenticate data sources and verify data non-repudiation. Through digital signature, users can prove the authenticity of data and prevent data from being tampered with or fraudulently used.

Message digest is to compress messages of any length into a fixed length digest, and to securely verify and encrypt the data. SM3 algorithm has been widely used in digital signature and message digest because of its high security and reliability, and supports large-scale data encryption and transmission processing.

SM3 algorithm plays an important role in international cryptography research. SM3 algorithm is a hash algorithm designed and popularized by the State Cryptography Administration, and has been approved by the State Cryptography Administration as China's national encryption standard. Moreover, SM3 algorithm has also received extensive attention in the field of international cryptography research, and many foreign experts have conducted special research and application.
