With the continuous development of information network technology, communication information security technology has become an important technical field, which has been widely concerned by the society, the army and the government $[1].$ China$$s financial, government and other important areas have entered the era of information network. Following the important areas of airspace, territorial sea and territory, information network has become the focus of national attention $[2].$ At present, the security of $$Corresponding author.

On the basis of the corresponding access privileges of different communication information, the access control tree is obtained by using attribute encryption algorithm, and the access privileges of different user attributes are calculated. According to the calculation results, the matching of user attributes and information privileges is realized by combining the access control tree, and the encryption of network communication information is completed. The difference between the encrypted communication information and the original communication information achieved by the algorithm is large, and there is a problem of low availability of information. Reference $[7]$ proposes an encryption algorithm for network communication information based on SM$4$ rounds of function design. Combining generalized Feistel structure and molecular cipher SM$4$ standard, a general structure design is obtained. Using mixed integer programming method, collision$-$resistant attacks are taken as security objectives to obtain different structures with different efficiency and size. Using the above structure, authentication encryption algorithm and message authentication code are constructed. and the authentication code is constructed, and the network communication information is encrypted by constructing authentication encryption algorithm. In the process of encrypting the communication information, the data is easy to be tampered with and stolen, and the integrity of the information is low. Reference $[8]$ proposes an encryption algorithm for network communication information based on improved genetic algorithm, which processes communication information by segmental encoding. On the basis of association rules, feature quantities of communication information are extracted. Data hiding of encoding information is designed by vector quantization fusion method. The improved genetic algorithm is used to construct the encryption key of network communication information, and the communication information is quantified and encrypted to complete the encryption of network communication information. This algorithm takes a long time to quantify the encoding of communication information and has the problem of low encrypting efficiency. Reference $[9]$ proposes an encryption algorithm for network communication information based on block cipher synchronization information. Random number is randomly acquired as synchronization information. Synchronization information is encrypted and protected by block cipher algorithm. Random number is used as key seed in sequence cipher algorithm, which is sequentially encrypted to obtain ciphertext. Synchronization information and ciphertext after encryption are transmitted to each other.
