Abstract： In order to improve the security and privacy of information network and strengthen the defense ability against network attacks, this paper proposes an information network security improvement strategy based on data encryption. Firstly, the links, nodes and end-to-end encryption are implemented to realize the whole process of information transmission encryption. Then, ZUC algorithm and SM2 algorithm are integrated. ZUC algorithm is responsible for encrypting and decrypting long packets, and SM2 algorithm is used to improve the secret key allocation problem in ZUC algorithm and improve the efficiency of encryption and decryption process. The experimental results show that the data transmission efficiency of the fusion ZUC algorithm and SM2 algorithm reaches 1 100 Mibit/s, and the computing resource space is 10 MB RAM. When the byte length is 512 bit and the plaintext data is 200 KB, the encryption time is 2.2 s, which is the shortest. When the byte length is 512 bit and the plaintext data is 300 KB, the encryption and decryption times are 3.74 s and 4.12 s respectively, which is the highest encryption and decryption efficiency among all algorithms. Therefore, the proposed strategy can effectively maintain a secure network environment and improve the privacy of user information.
