Abstract: In recent years, major companies have continuously strengthened the construction of data centers, and the security of data link transmission has become an urgent problem to be solved. Considering that SM cryptographic algorithms have begun to show its superiority compared with the international general cryptographic algorithm, this paper combines the advantages of symmetric encryption, asymmetric encryption and digital signature technology in SM cryptographic algorithms, and proposes a data link security transmission method based on the national secret SM2 algorithm, SM3 algorithm and SM4 algorithm. Experiments show that this method has a good effect against passive attacks and active attacks, and can significantly improve the security of data transmission between stations in two-level data.
