Step S510: and performing grouping processing on the first communication data information to obtain a plurality of information combinations of the first communication data information.
It should be noted that there are many ways to perform packet processing on the first communication data information, such as integer packet processing or other packet processing ways, which are not limited herein, and assuming that the integer packet processing is performed on the first communication data information, the first communication data information may be divided into 2 groups, 3 groups, 5 groups, or more groups, which may be selected according to actual situations, which is not limited herein.
Step S520: and carrying out asymmetric encryption processing on the plurality of information combinations according to a private key in the public key system model to obtain a communication data ciphertext.
It should be noted that the communication data ciphertext can only be owned by both communication parties.
In this step, there are many ways to perform asymmetric encryption processing on a plurality of information combinations, for example, RSA (Rivest-Shamir-Adleman) Algorithm or DSA (Digital Signature Algorithm) may be used, and the like, which is not limited herein. The RSA encryption algorithm is an algorithm proposed by r.l.river, a.shamir, and l.adleman and named by their three names, and includes a key pair consisting of a public key and a private key, where the public key has an open characteristic and the private key is kept by a user.
In this embodiment, by using the data transmission method from step S510 to step S520, multiple information combinations of the first communication data information can be obtained by performing packet processing on the first communication data information, and finally, the multiple information combinations are subjected to asymmetric encryption processing according to the private key in the public key system model to obtain a communication data ciphertext.
In one embodiment, the key generation process based on RSA algorithm includes the following specific steps:

Step S720: and obtaining a decoding probability threshold according to the data transmission throughput.
In this step, the decoding probability threshold can be determined according to the data transmission throughput, so that the probability of data stealing is reduced, and the security of data transmission is improved.
Step S730: and obtaining the data transmission rate according to the decoding probability threshold and the data information acquisition probability threshold.
