Abstract
The invention provides a video segment encryption and playing method based on random encryption. The method comprises performing video segment processing, appointing a random code for a segment header sign, and performing byte encryption processing according to the random code appointment, and decrypting and playing the video segment according to a random code algorithm by use of the authorization of a dedicated player. The decrypting and playing can be performed without the supporting of a server when the algorithm is used for decrypting and playing, so that the method can be extensively applied to various playing environments.
Description
Technical field
The present invention relates to video-encryption field, more particularly to a kind of video segment encryption and broadcasting side based on accidental enciphering
Method.
Background technology
As nowadays the multimedia resources such as the development of Internet technology, video/audio are widely used to amusement, study is done
In the various application systems such as public affairs.But due to the opening of the Internet, what the video resource to possessing intellectual property was not stolen
Protection work just becomes particularly important.Traditional Video Encryption Algorithm is difficult to meet in different platform, plays in varying environment and receives
The requirement of protection video resource, accordingly, it would be desirable to a kind of Video Encryption Algorithm for adapting to various playing environments carries out adding to video
Privacy protection.
The content of the invention
The present invention provides a kind of encryption of video segment and player method, to solve existing video-encryption technology in safety
Difference, the problems such as network environment has high demands.This method includes video segment process, section head mark agreement random code, by random
Code agreement carries out byte encryption, is played by the decryption of random code algorithm using special player mandate, and concrete technical scheme is such as
Shown in lower：
A kind of video segment encryption method based on accidental enciphering, comprises the steps：
Step 1) slicing treatment is made to source video, section time span can be set according to demand；
Step 2) file header type flags process is carried out using agreement random code to each section；
Step 3) each section is encrypted by the corresponding byte AES of random code to section, can accomplish
Each section is encrypted using different AESs；
Further, the step 2) in agreement random code be：A random length out is little more than 10 during encryption
The bytecode of section head is written in 255 digital arrays, it is random code length value to set first value, and second value is agreement
Positional value of the AES code name in random code. such as random code is 11,5,3,6,45,9,66,2,1,4,78, then representing should
Random code accounts for 11 bytes, and the 6th byte value 9 (from the beginning of 0) is AES code name.
Further, the step 3) in encryption method be：Set AES code name be set to as 1, about to cut into slices it is every
Process is compressed to 50 bytes every 100 bytes (after random code). code name 2 is about set to section every 100 bytes
Carry out carrying out 50 bytes to the process of 5 XORs. various AES can be set, different encryption generations are then corresponded to
Number, effectively reduce the risk being decrypted.
A kind of video segment player method based on accidental enciphering, comprises the steps：
Step 1) using dedicated video player section is loaded in order or according to the loading correspondence section of specified time point
File；
Step 2) analysis section header byte flag code；
Step 3) byte decryption is carried out using correspondence decipherment algorithm according to the flag code for obtaining；
Step 4) broadcasting in the data addition video playback stream after decryption.
The beneficial effects of the present invention is：This AES is applied to pc, and android, ios etc. be multi-platform to carry out video
Encryption is played and makes to the resources and knowledge property right to be protected, and using section play-back technology, allows player to take saltatory
Loading user specifies the slice of data of time point being decrypted broadcastings, it is not necessary to loads and does not need fragment data. in network environment
During middle broadcasting, server stress is mitigated significantly and is paid wages with bandwidth, lift Consumer's Experience, section broadcasting can also facilitate clear to difference
Clear degree video source carries out seamless switching, using random labelling pattern each section can be caused to take difference in theory
AES be encrypted, significantly increase the difficulty for cracking encrypted video, the safety for making protection video is greatly improved.
Description of the drawings
Fig. 1 is the FB(flow block) of the present invention；
Specific embodiment
Below by preferred embodiment shown with reference to the accompanying drawings, the present invention is explained in detail, but be the invention is not restricted to
The embodiment.
As shown in Figure 1 step is as follows：
1. pair source video makees slicing treatment, can according to demand arrange section time span；
2. pair each section carries out file header type flags process using agreement random code；Arranging random code is：During encryption
A random length out is written to the bytecode of section head more than 10 less than 255 digital arrays, and first value of setting is
Random code length value, positional value of second value for agreement AES code name in random code. such as random code is 11,5,3,
6,45,9,66,2,1,4,78, then represent that the random code accounts for 11 bytes, the 6th byte value 9 (from the beginning of 0) is AES
Code name.
3. pair each section is encrypted by the corresponding byte AES of random code to section, can accomplish each
Section is all encrypted using different AESs；Encryption method is：Set AES code name to be set to as 1, about to cutting
Piece is compressed process every 100 bytes (after random code) to 50 bytes. and code name 2 is about set to section every 100
Byte carries out carrying out 50 bytes to the process of 5 XORs. and various AES can be set, different adding then is corresponded to
Close code name, effectively reduces the risk being decrypted.
A kind of video segment player method based on accidental enciphering, comprises the steps：
1. using dedicated video player section is loaded in order or according to specified time point loading correspondence section file；
2. section header byte flag code is analyzed；
3. byte decryption is carried out using correspondence decipherment algorithm according to the flag code for obtaining；
4. playing in the data addition video playback stream after decryption, in actual use, using dedicated video player
Authorize and be decrypted broadcasting according to file header type flags code acquisition decipherment algorithm to being loaded into cut into slices.
As user terminal capacity of memory device is increasing, for more preferable Consumer's Experience, mitigate video resource service
Device pressure, and user carries out video playback under without network state, and having carries out the need of local cache process to video file
To ask. the decryption of this algorithm can be accomplished to be decrypted broadcasting without the need for server support when playing, and be widely applicable to various broadcastings
In environment.
Above specific embodiment is only unrestricted to illustrate technical scheme, although with reference to example to this
