The need for data protection in national critical information infrastructure units has become more and more urgent with the deepening of digital transformation. At present, the rapid development of science and technology makes the secure transmission of data in the process of system interaction face a major challenge. In order to solve this challenge, a secure data transmission and storage scheme based on the state secret algorithm is designed in the system of this paper. By using a mixture of SM2, SM3 and SM4 algorithms and studying the anti-replay and anti-tampering mechanisms, the secure transmission of data in the system is realized. The SM2 and SM3 algorithms are incorporated into the design of the system, which not only guarantees the security of data transmission, but also ensures the integrity of the data. For data storage, SM4 and SM3 algorithms are used to ensure the confidentiality and integrity of the data, and have a repair mechanism. In order to effectively prevent data replay attacks and tampering attacks, the system introduces timestamp and random number mechanisms, which further improves the security of system data. In summary, the research on system data security based on the state secret algorithm proposed in this paper not only realizes the goal of data confidentiality, but also provides a strong security guarantee for the data transmission and storage of the system.
