Another part whitepack of binding is held, and another part whitepack is combined with the part whitepack pre-generated, to obtain and client
Hold the whitepack algorithm of binding.The data processing method of the embodiment of the present invention is described in detail with reference to the accompanying drawing.
Referring to Fig.1, a kind of step flow chart of data processing method embodiment of the invention is shown, service is applied to
Device, this method can specifically include following steps:
Step 100, the first client whitepack algorithm is generated, target random number corresponding with target matrix is saved；
Wherein, the first client whitepack algorithm includes pre-arranged code and internal at least two data obscured of process
Table, wherein the target matrix is the tables of data being disposed adjacent at least two tables of data with the pre-arranged code；
In embodiments of the present invention, step 100 is first carried out before receiving the request of data of client in server
A part of whitepack (the first client whitepack algorithm i.e. here) not with client binding is generated.
Step 101, request of data is received, the request of data includes client id information；
Wherein, server can receive the request of data of client, which can request for whitepack.

The request of data sent to server may include client id information.
Optionally, when executing the step of the generation the first client whitepack algorithm in step 100, referring to Fig. 2, root
It can be realized by step 201~step 203 according to the method for the embodiment of the present invention, and execute the guarantor in step 100
When depositing the step of target random number corresponding with target matrix, then it can be realized by step 204~step 205:
Step 201, it according to preset-key, default Processing Algorithm, random number, generates by internal at least two numbers obscured
According to table；
Specifically, needing due to generating whitepack using random number, to obscure key and algorithm, therefore can give birth to
Random matrix is generated at random number, and using random number；According to preset-key, default Processing Algorithm, the random matrix, next life
At by the internal whitepack table (the whitepack table includes at least two tables of data) obscured, the whitepack table is via no any rule
Random mix avoids key from being cracked.Wherein, any one tables of data all have passed through internal mix when generating in whitepack table
Confuse, therefore, each tables of data in whitepack table corresponds to one group of random number.
Wherein, which can be any one symmetry algorithm, such as AES (Advanced Encryption
Standard, Advanced Encryption Standard), DES (Data Encryption Standard, data encryption standards) etc..
In addition, then generated using Encryption Algorithm and to be obscured by inside when the request of data is request encryption whitepack
Whitepack table；When the request of data is request decryption whitepack, then the whitepack table obscured by inside is generated using decipherment algorithm.
In one example, Fig. 3 shows the table structure of the first client whitepack algorithm of generation of the embodiment of the present invention.Such as
Shown in Fig. 3, the first client whitepack algorithm includes pre-arranged code (Table A and table B) and the warp that is distributed between Table A and table B
Cross the internal multiple tables of data obscured (including each tables of data unlisted in 1~table of table 8 shown in figure and figure).
Step 202, according to unit matrix, pre-arranged code is generated；
Wherein, in order to utilize the client id information received based on the first client whitepack algorithm, have to generate
The second client whitepack algorithm that outside is obscured, when generating the first client whitepack algorithm, can also according to unit matrix come
Generate pre-arranged code.In other words, it can use unit matrix to generate one or two tables of data, the two tables of data are being schemed
Table A and table B are corresponded respectively in 3.The purpose for generating Table A and table B is, in pre-generated part whitepack shown in Fig. 3,
For another part whitepack reserved location generated in real time.Table A and the position where table B are the reserved location of another part whitepack,
Namely another part whitepack (obscuring coding in outside i.e. described hereinafter) generated in real time institute in the second client whitepack algorithm
Position.
Wherein, generated using unit matrix in the principle and traditional whitepack encryption and decryption technology of the method for tables of data using with
Machine matrix is similar come the principle for generating the method for the tables of data obscured without outside, and which is not described herein again.In addition, here for giving birth to
Order at the unit matrix of pre-arranged code is identical as generating the external order of random matrix for obscuring coding.
It should be noted that in the present embodiment by taking unit matrix as an example, to illustrate the generating mode of pre-arranged code, and at it
In his embodiment, the present invention is not restricted to unit matrix for the matrix-type for generating pre-arranged code, can also be benefit
Any one random matrix caused by random number.Because the purpose for generating pre-arranged code is pre- Mr. shown in Fig. 3
At part whitepack in, for another part whitepack (i.e. external the obscure coding) reserved location generated in real time, whether which kind of square
Battle array pre-arranged code generated will all be obscured coding by outside and replace, and therefore, the present invention is for generating the square of the pre-arranged code
The type of battle array is with no restrictions.Pre-arranged code is generated used here as unit matrix to be advantageous in that without generating random matrix, is subtracted
Few operating procedure, promotes the response speed of server.
Wherein, the present invention for step 201 and step 202 execution sequence with no restrictions.
Step 203, the pre-arranged code is disposed adjacent at least two tables of data, generates the first client whitepack
Algorithm；
As shown in figure 3, Table A and table B can be separately positioned on to the two sides for the whitepack table obscured by inside, so that Table A
It is disposed adjacent with 1~table of table 4, table B is disposed adjacent with 5~table of table 8, wherein table shown in Fig. 3, i.e. the first client whitepack
One complete look-up table of Algorithm constitution.In this example, as shown in figure 3, one for input data of Table A and the whitepack table
Side is disposed adjacent, and table B is disposed adjacent with the side for output data of the whitepack table.
Step 204, target matrix adjacent with the pre-arranged code at least two tables of data is identified；
As shown in figure 3, the target matrix adjacent with Table A (including table 1, table 2, table 3 and table 4) can be recognized, with table B
The target matrix (including table 5, table 6, table 7 and table 8) being disposed adjacent.
Step 205, target random number used when generating the target matrix is recorded.
Wherein it is possible to which the target random number (that is, 8 groups of random numbers) used respectively when by generation 1~table 8 of table is recorded in number
According in library, also, this 8 groups of random numbers respectively correspond above-mentioned 8 target matrixes.
Further, since the second client whitepack algorithm may include an outside obscure part or two outsides obscure portion
Point, therefore, in the example depicted in fig. 3, shows and be used to form Table A and table B that part is obscured in subsequent two outsides；Work as use
Client id information only generates an outside when obscuring part, then may include in the first pre-generated client whitepack algorithm
Table A or table B, rather than the two includes, specifically the principle of the second client whitepack algorithm of generation is similar, outer with two herein
Portion obscure part come for example, it should be appreciated to those skilled in the art that an outside obscure the implementation principle of part with
The implementation principle that part is obscured in two outsides be it is similar, therefore, no longer repeat one by one herein.
In this way, the server of the embodiment of the present invention before receiving the request of data of client, has just pre-generated warp
The internal whitepack table (including at least two tables of data) obscured is crossed, at least side in the two sides of whitepack table is provided with using single
The pre-arranged code that bit matrix generates, Lai Shengcheng obscure without outside, and only internal the first client whitepack algorithm obscured；
And the target matrix adjacent with pre-arranged code used target random number when generating is stored in advance；So receiving
After the request of data of client, it is only necessary to utilize client id and target matrix and target random number, so that it may in real time
Generation obscure and there is the outside of client id to obscure coding, so that pre-arranged code, which is replaced with outside, obscures coding, generate second
Client whitepack algorithm, realizes the binding of client whitepack and client id, and saves a large amount of time for generating whitepack,
Client can be responded faster, the second client whitepack algorithm of return to client, and reduce server in sound
Answer the expense when request of data of client.
It optionally, according to the method for the embodiment of the present invention can also include: head before step 101 and step 201
First, the data ID of server storing data is obtained；Then, according to pre-set data ID and key, Processing Algorithm
Corresponding relationship, obtain with the matched preset-key of the data ID and default Processing Algorithm.
Specifically, the method for the embodiment of the present invention can be to be stored in each data of server side key is respectively configured
And Processing Algorithm (including encryption or decryption algorithms).
Wherein, the type for the data that the present invention stores server side with no restrictions, such as video data, audio number
According to, document data etc..The data are the data that server can be distributed to client, and client-side can be to received from server
The data carry out encryption or decryption process.Certainly under majority scene, the data that server is issued to client are data ciphertext,
The second client whitepack algorithm that client-side then needs to be issued using the server of the method for the embodiment of the present invention, carrys out logarithm
It is decrypted according to ciphertext.
It being illustrated by taking video data as an example, server side can be key, the Processing Algorithm of each video distribution fixation,
So that some video may only be encrypted or be solved using the whitepack algorithm that the key and algorithm for corresponding to the video generate
Close processing.
After the video data storage of server side is completed, the method for the embodiment of the present invention can be for each video ID
Corresponding key and Processing Algorithm are set, thus generate pre-set video ID and key, Processing Algorithm it is corresponding
Relationship.Such as video 1 corresponds to key 1 and AES encryption algorithm；Video 2 corresponds to key 2 and DES decipherment algorithm.
So in pre-generated first client whitepack algorithm, the method for the embodiment of the present invention can be closed according to the correspondence
System, to obtain the corresponding key of each video ID and Processing Algorithm.
So when executing step 201, then according to random number and the matched preset-key of the data ID and it can preset
Processing Algorithm generates corresponding with the data ID by internal at least two tables of data obscured.
Here, when generating video 1 by internal at least two tables of data obscured, then random using what is generated at random
Number, and key 1 corresponding with video 1 and AES encryption algorithm generate at least two tables of data obscured by inside.To view
Frequently 2 when generating by internal at least two tables of data obscured, then uses the random number generated at random and corresponding with video 2
Key 1 and DES decipherment algorithm generate by least two tables of data obscured of inside.
Wherein, different based on used algorithm when generating whitepack table, the second client whitepack ultimately generated can be made
The purposes of algorithm is different, such as corresponding to the second client whitepack algorithm 2 generated of video 1, special for having the client
The video data that video ID is video 1 is encrypted in the client for holding ID；For another example, correspond to video 2 generated the
Two client whitepack algorithms 2, it is special for having the client of the client id, to the video data that video ID is video 2 into
Row decryption processing.
In addition, after step 203, can also include: according to the method for the embodiment of the present invention generate the data ID with
Corresponding relationship between the first client whitepack algorithm.
Wherein, since each video of server side storage is corresponding with respective key and algorithm, pre- Mr.
At the first client whitepack algorithm be also required to be bound with the ID of corresponding video.Such as video 1 and the first client it is white
Box algorithm 1 is corresponding, and video 2 is corresponding with the first client whitepack algorithm 2.
In this way, the embodiment of the present invention is preset between the data ID and key, Processing Algorithm of the data of server storage
Corresponding relationship, and the corresponding key of each video ID and Processing Algorithm are obtained using the corresponding relationship, then making base
Incidence relation can be established with video ID in key and Processing Algorithm the first client whitepack algorithm generated, thus taking
Being engaged in device side can be for each stored data, pre-generated the first client whitepack algorithm mutually bound with each data.
Convenient for carrying out classification storage to the corresponding whitepack algorithm of each storing data.Realize the independent encryption to different data, solution
It is close.And the second client whitepack algorithm ultimately generated not only can mutually be bound with client id, it can also be with video ID
It mutually binds, then client may only then use and this when carrying out encryption or decryption oprerations to the data from server side
Client id binds and carries out encryption or decryption oprerations with the second client whitepack algorithm of data binding, improves data
Safety.
Step 102, it according to the client id information, the target matrix and the target random number, generates external
Obscure coding；
Wherein, the first client whitepack algorithm generated is only obscured by inside before the data request is received, also
It is not bound with client id, therefore, this step can use the institute in the client id information and the first client whitepack algorithm
Target matrix and the corresponding target random number of the target matrix are stated, obscures coding to generate outside.
Wherein, it is identical that the quantity of coding and pre-arranged code described in above-mentioned steps 202 is obscured outside this.
That is, if being provided with Table A as shown in Figure 3, needing exist for giving birth in the first client whitepack algorithm
At Table A '；If being provided with table B as shown in Figure 3, generation table B ' is needed exist for.Wherein, Table A ' and table B ' be located at
In two client whitepack algorithms before and after default Processing Algorithm (Encryption Algorithm or decipherment algorithm).
Use for the second client whitepack algorithm, is described briefly here:
Obscure if the second client whitepack algorithm shown in Fig. 4 have passed through outside, including Table A ' and table B ', number to be decrypted
According to being 7, then client can pass through Table A ' it is inverse become 6 for 7, then, client is input to the second client whitepack for 6 and calculates
Method.The inverse of second client whitepack algorithm, first with Table A ' offset Table A ' obscures operation, that is, is reduced to 7 for 6,
The whitepack table in the second client whitepack algorithm is recycled, to be decrypted to 7, generates 12；12 are mixed followed by table B '
Confuse into 15 outputs；Finally, client recycles the inverse counteracting table B's ' of table B ' to obscure operation, it is, being reduced to 12 for 15, make
The ciphertext data 12 that must be ultimately generated is to have carried out the result of decryption oprerations merely with preset-key and default decipherment algorithm.
Optionally, the first client whitepack algorithm can be white for embodiment illustrated in fig. 2 the first client generated
Box algorithm, that is, the first client whitepack algorithm include by least two tables of data obscured of inside and with it is described at least
The pre-arranged code that two tables of data are disposed adjacent.
It optionally, can be firstly, obscuring plan using default according to the client id information when executing step 102
Slightly, Obfuscating Algorithms are generated；Then, it according to the Obfuscating Algorithms, the target matrix and the target random number, generates external
Obscure coding.
Wherein, the structure of Obfuscating Algorithms can be matrix queue.
The default aliasing strategy can be acquisition cryptographic Hash, then server is obscured according to client id using default
Strategy then can carry out Hash operation to client id, obtain the cryptographic Hash of client id come when generating Obfuscating Algorithms, then,
Using the cryptographic Hash of the client id as the Obfuscating Algorithms (such as confusion matrix C1)；
Alternatively, the default aliasing strategy can be using the seed of random function and generate random number, then server exists
It, then can be to using client id as random function using default aliasing strategy come when generating Obfuscating Algorithms according to client id
Seed, random number A is generated with the seed, then, (such as obscures square for the random number A of generation as the Obfuscating Algorithms
Battle array C2).
When obscuring coding outside generation, then it can use 1~table of table adjacent with Table A in the confusion matrix and Fig. 3
4, coding 1, i.e. Table A are obscured to generate outside '；And 5~table of table 8 adjacent with table B in the matrix queue and Fig. 3 is utilized,
Coding 2, i.e. table B ' are obscured to generate outside.
In this way, utilizing client when coding is obscured in outside of the embodiment of the present invention in the second client whitepack algorithm of generation
Hold id information and default aliasing strategy, Lai Shengcheng Obfuscating Algorithms (i.e. matrix queue), so that covering client in matrix queue
Hold id information；Then, number of targets adjacent with the pre-arranged code in the matrix queue and the first client whitepack algorithm is utilized
According to target random number corresponding to table and target matrix, coding is obscured to generate outside, so that volume is obscured in the outside generated
Code is mutually bound with client id, so that the second client whitepack algorithm ultimately generated is also bound with client id, so that only
Encryption or decryption that the second client whitepack algorithm carries out data just can be used in the client for possessing the client id, it is ensured that
The safety of data.
Optionally, described according to the Obfuscating Algorithms, the target matrix and the target random number in execution, it generates
When the step of coding is obscured in outside, matrix multiplication operation can be carried out to the Obfuscating Algorithms and the target matrix first；
Finally, the result and the target random number that generate by the matrix multiplication operation are made XOR operation, to generate outside
Obscure coding.
Referring to shown in Fig. 3 and Fig. 4, for example, the corresponding random number 1 of table 1, the corresponding random number 2 of table 2, the corresponding random number 3 of table 3, table 4
Confusion matrix C and table 1 then can be carried out matrix multiplication operation here by corresponding random number 4, by the result of matrix multiplication operation with
Random number 1 carries out XOR operation, generates table 1 '；Confusion matrix C and table 2 are subjected to matrix multiplication operation, by matrix multiplication operation
Result and random number 2 carry out XOR operation, generate table 2 '；Confusion matrix C and table 3 are subjected to matrix multiplication operation, by matrix
The result and random number 3 of multiplying carry out XOR operation, generate table 3 '；Confusion matrix C and table 4 are subjected to matrix multiplication fortune
It calculates, the result of matrix multiplication operation and random number 4 is subjected to XOR operation, generate table 4 '；Finally, by table 1 ', table 2 ', table 3 ' and
Table 4 ' puts in order according to table 1, table 2, table 3 and table 4, generates outside as shown in Figure 4 and obscures coding --- Table A '.For figure
The generating mode of 4 total table B ' and Table A ' generating mode it is similar, difference uses used 1~table of table 4, replace with table 5~

It is next targetedly only to obtain and be somebody's turn to do according to the corresponding relationship between pre-set data ID and the first client whitepack algorithm
Corresponding the first client of the target whitepack algorithm of data ID in request of data, and by the first client of target whitepack algorithm
In the pre-arranged code replace with the outside and obscure coding, it is corresponding with the data ID in the data processing request to generate
The second client whitepack algorithm.
In this way, the server of the embodiment of the present invention can in advance for different data generate respectively it is corresponding without
The first client whitepack algorithm that outside is obscured is used to carry out encryption or decryption process to some target data to client request
Client whitepack algorithm when, recycle the client id of the client and corresponding the first client of target of the target data
Whitepack algorithm is obscured to carry out outside to target the first client whitepack algorithm, it is made to obscure the id information for having the client.
So only with the client id client, just can be used the second client whitepack algorithm come to the target data into
The operation such as row encryption/decryption/signature, it is ensured that one between encryption/decryption/signature of client, data and data is a pair of
It should be related to, improve data safety degree.
Optionally, the request of data further includes the acquisition modes of client id information, before step 102, can be sentenced
Whether the acquisition modes for the client id information of breaking are default acquisition modes；If the acquisition modes of the client id information are
Default acquisition modes, then follow the steps 102.
Wherein, for client before sending request of data to server, client can identify obtaining for client id information
Mode, such as the client id information is taken to be come by which function passes, then can not only make to count when sending request of data
According to request carry client id information, also make its carry client id information acquisition modes (such as transmit the client id letter
The function name of the function of breath).
So the acquisition modes which is legal client id, such as function 1, function can be set in server side in advance
2 is legal, other functions are not illegal.Server side can parse it after receiving the request of data of client, obtain
The acquisition modes of client id information are got, and judge whether the acquisition modes are default acquisition modes, are here discriminant function
Whether name is preset function name, if so, illustrating that the client is the client with the client id information, executes step
102, Lai Zhihang are subsequently used for generating the step of being bound to the second client whitepack algorithm of the client；On the contrary, if it is not, then saying
Client id information transmitted by the bright client may be not the practical client id information of the client, it may be possible to steal
It is derived from the id information of other clients having permission, then step 102 can not be executed in order to ensure the safety of key, or
Person generates the second client whitepack algorithm using a false key, even if then client to receive second client white
Box algorithm also can not accurately be encrypted/decryption/to data and the operation such as be signed.
