All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The method aims to solve the defects that in the prior art, paper simulation seismic record data has seismic waveform deformation and stains due to the fact that the age of the paper simulation seismic record data is long, or the paper is aged and fragile due to time, so that accurate research on the paper simulation seismic record data is difficult to conduct directly, scientifically and meticulously.
Fig. 1 is a flowchart of a video data transmission method according to an embodiment of the present invention, as shown in fig. 1, where the video data transmission method is executed by a video data transmission apparatus, the video data transmission apparatus includes a splitting end and a recombining end, and the method includes:
s1, the splitting end sends a data transmission request to the recombining end;
s2, the restructuring end responds to the data transmission request to generate the asymmetric encryption key and sends a public key in the asymmetric encryption key to the disassembling end;
s3, the splitting end encrypts a pre-generated symmetric encryption key by using a public key;
s4, the recombination end decrypts the symmetric encryption key generated by the splitting end by using the asymmetric encryption private key;
s5, the splitting end encrypts the video data to obtain a transmission unit, and sends the transmission unit to the recombination end to decrypt a symmetric encryption key generated by the splitting end by using an asymmetric encryption private key;
and S6, the recombination end analyzes the transmission unit by using the symmetric encryption key to obtain the video data.
The splitting end (client) may be a node that splits, encrypts and transmits h.264 encoded data, and such nodes include but are not limited to terminals such as a general computer, a smart phone, and an IoT device. The node is used for splitting, encrypting and sending the H.264 video coding data, and relevant codes are deployed in the node. The reassembly end (server) may be a node that reassembles the data from the splitting end to restore the original complete data. The node is used for decrypting and recombining the data from the splitting end and processing some error conditions, and related codes are deployed in the node.
In one possible implementation manner, the symmetric encryption key may be a symmetric encryption key that the splitting end generates fragmented data, and the encryption key is used to symmetrically encrypt the fragmented data. The asymmetric encryption key can be a public key and a private key which are generated by the recombination end and are asymmetrically encrypted, and the public key is transmitted to the splitting end, the public key is used for encrypting the symmetric encryption key, and the private key is used for decrypting the symmetric encryption key encrypted by the public key.
In one possible implementation manner, the transmission unit includes an encrypted fragment data sequence number, an encrypted fragment data length, and an encrypted fragment data pointer. And in the analysis process, video data can be obtained according to the encrypted fragment data serial number, the encrypted fragment data length and the encrypted fragment data pointer.
In the implementation mode, for an H.264 coding video file at the splitting end, the splitting end firstly acquires the asymmetric encryption public key from the restructuring end, then generates the symmetric encryption key by itself, and sends the asymmetric encrypted symmetric encryption key to the splitting end. Then, for the h.264 encoded video file to be transmitted, the splitting end splits each frame data according to the frame header feature (0x00000001 or 0x000001), thereby obtaining a plurality of sliced data.
In the splitting process, each piece of data is encrypted by using a symmetric encryption key, so that encrypted piece data is obtained. And the splitting end encapsulates the encrypted fragment data, adds a serial number mark to form a transmission unit, and transmits the transmission unit to the recombination end through a carrier. And after the recombination end receives the transmission units, the encrypted data in the transmission units are decrypted by using the symmetric encryption key, and are recombined according to the serial numbers in the transmission units, and finally the H.264 encoded data at the splitting end is obtained.
According to the video data transmission method and device provided by the embodiment of the invention, the H.264 coded video data is subjected to fragmentation and encryption processing, plaintext information and characteristics in the transmission process are eliminated, and then the data subjected to fragmentation and encryption is packaged into the data field of the carrier and transmitted to the server side for analysis, so that the confidentiality in the video data transmission process is ensured. Meanwhile, as the video data is scattered into different fragments for transmission, the size of the transmitted data is uniform, the information of the transmission file is difficult to leak through attack methods such as a side channel and the like, and the hidden transmission of the H.264 coded video data is further realized.

The fragmentation data may be split by the splitting end according to a certain rule, and the split minimum unit is the fragmentation data. The encrypted fragment data may be that the split end encrypts the fragment data, and the encrypted fragment data is the encrypted fragment data. The transmission unit can be a split end which encapsulates the encryption fragment data and adds the serial number, the data length and the like of the encryption fragment data in the original H.264 coded data.
In a possible implementation manner, the parsing, by the reassembly terminal, the transmission unit by using the symmetric encryption key to obtain the video data specifically includes: and the recombination end decrypts and recombines the transmission unit by using the symmetric encryption key to obtain the video data.
In this implementation, the decryption and reassembly of the transmission unit may be understood as the inverse operation of encryption and fragmentation, which is not described herein again.
In one possible implementation, the splitting end relies on a carrier to transport the transmission unit to the recombining end.
The carrier may be a protocol for transmitting the fragmented encrypted data, and may be a network protocol such as HTTP. In this implementation manner, the encrypted data may be encapsulated in the transmission unit, and the transmission unit may be integrally placed in another protocol carrier (e.g., a data part of HTTP/a protocol such as SNMP) and transmitted to the reassembly terminal.
