for example, in chinese patent with grant publication No. CN102752102B, a packet segmentation and encryption transmission processing method and apparatus are disclosed, where the method includes a packet transmission processing at a medium access control layer: firstly, carrying out segmentation pretreatment on a data packet according to data packet configuration information and a segmentation threshold value; then, prior to performing the first segment transmission process, configuring the required control data for the first segment encryption; when each preset segment sending process is executed, encrypting the current segment and simultaneously executing the operation of sending the control data needed by the encryption of the last segment and the configuration of the next segment; the steps can be repeatedly executed to send out the single segments one by one, so that the segment encryption transmission processing operation of the whole data packet is completed. The data packet segmentation encryption transmission processing method and the data packet segmentation encryption transmission processing device can save storage space and data packet transmission processing time and ensure efficient transmission processing of data packet segmentation transmission;

And adopting an end-to-end real-time encryption method based on a stream cipher algorithm, negotiating session parameters and respectively establishing a cipher table by two communication parties in a session initialization stage. The sender extracts the data packet header information to generate a key stream starting point, and generates a section of key stream exclusive or encrypted data packet load according to the key table and the starting point. The receiving side judges whether network packet loss exists according to the packet header information of the data packet, when the packet loss exists, the receiving side firstly completes the synchronization of the cipher table, and then generates a synchronous key decryption data packet load based on the updated cipher table and the starting point. The application realizes the real-time encryption technology with the key self-synchronization function under the network condition of packet loss on the basis of not additionally increasing network communication flow and generating key stream on line in real time.
The problems proposed in the background art exist in the above patents: however, in the data packet transmission process, not all information needs to be encrypted, so that the encryption of the information definitely improves the encryption complexity, for example, in the device operation process, not all operation data need to be encrypted, only the fault data transmission of the operation of the encryption device is not detected by the outside, but the data needing to be encrypted cannot be quickly and accurately searched in the prior art, and in order to solve the problems, the application designs a data packet transmission method and a data packet transmission system based on the data encryption.
