Description
Technical field
The invention belongs to field of cloud calculation, more particularly to a kind of cloud synchronous method of privacy fragment file.
Background technology
User information store method in the prior art is to take file to a network by transmission of network from client
Business device, corresponding user information can then be downloaded by logging in the network server from the arbitrary node of network.However, hacker is by stealing
The server info can steal the user information, invade privacy of user.Also there is the cloudy storage of fragmentation in the prior art simultaneously
Method, but this method is to user information there is no the processing such as being encrypted, also according to matrix column progress user's letter
Cease the method for fragmentation.This method encrypts the combination of the cooperation cloudy storage method of fragmentation by first time, is protected to privacy of user
Shield is more significant.
Invention content
The purpose of the present invention is to provide the cloud platform method for secret protection that a kind of fragmentation encrypts user information.
The present invention uses following technical scheme to achieve the goals above：
Fragmentation encrypts the cloud platform method for secret protection of user information, it is characterised in that includes the following steps：
Step 1：Unicode form coding conversions are carried out to core customer's information, are preserved into 16 system character shapes after conversion
Formula, such as " 9A62 ", " 5B3A "；
Step 2：Character style is converted into 5 characters, first ' 0 ' character of addition if only four, such as " 9A62 "
It is converted into " 09A62 "；
Step 3：Upset 5 characters and carry out simple encryption, selects encryption complexity x, x a value 1,2,3,4,5：
Step 3.1：The integer a in [1, a 5] range is generated at random, and position exchange processing, processing are carried out to 5 characters
Process is that a characters are transposed to first.
Step 3.2：Step 3.1 is repeated, until number of repetition is equal to encryption complexity x, the integer that will be generated at random every time
It is preserved in order, finally obtains x encryption：a1a2..., aiRepresent the integer that ith generates at random.
Step 4：Each user information of secret protection will be needed to carry out step 1,2,3 processing respectively, and protected using by row
It deposits, a user of behavior one, the form that preserved per a line is { five characters ... after five character _ conversions after encryption son _ conversion },
User information is referred to as encryption user information after the step；
Step 5：The Cloud Server quantity N of cloudy server is counted, and encryption user information is converted into matrix form, square
Each in battle array preserves a character of encryption user information；
Step 6：Matrix is subjected to cutting, the character data of different lines is saved in different Cloud Servers, specific rules are：
Cloud Server is encoded：Such as N0、N1、N2..., M is encoded according to column number respectively to matrix0、M1、M2..., specifically
Rule is preserved as according to MiSubscript i carries out data distribution：
T=i%N is calculated, it is N that the column data that result of calculation is T, which is saved in cloudy server number,TCloud Server
On, each columns is stated to be fragmentation encryption user information.The machine needs to preserve basic metadata information, metadata letter simultaneously
Breath is the holding time, and Cloud Server routing information of preservation etc. (can find crumb data) according to metadata.
Step 7：The storage information of cloudy server is obtained according to the metadata information of the machine, and finally realizes that fragmentation adds
Fragmentation encryption user information can be combined into encryption user's letter by the acquisition of close user information again according to metadata information
Breath.
Step 8：The decryption of user information is encrypted, 5 character informations are finally obtained：
Step 8.1：By the encryption user that format is { five characters ... after five character _ conversions after encryption son _ conversion }
Information is split, extraction encryption and five character strings.
Step 8.2：It is reversely decrypted according to encryption, selects last the sub- a of encryption every timei, by five characters
The first bit transition to aiPosition.
Step 9：5 character reverses are changed to correct Unicode format, are reduced to original user information.
In above-mentioned technical proposal, generated again by random digit generation method after user information is converted into 5 character styles
5 characters are encrypted in encryption.
In above-mentioned technical proposal, according to the Cloud Server quantity N of cloudy server, encryption user information is subjected to cutting simultaneously
It is synchronized on different Cloud Servers, is a kind of by information fragmentation and the method that is retained separately.
In above-mentioned technical proposal, it can lead to after fragmentation encryption user information is stored on the different server of cloud platform
The inverse process that metadata realizes fragmentation encryption user information is crossed, is finally converted to the user information of core again.
Because the present invention uses above technical scheme, has following advantageous effect：
The invention discloses the cloud platform method for secret protection that a kind of fragmentation encrypts user information, method is by simply adding
The cloudy storage of close and encryption information fragmentation is combined to protect user information.User kernel privacy information content is often very heavy
It wants and on a small quantity, a simple encryption is carried out by the way that user information is converted into Unicode codings, then by user information
Fragmentation is handled and is distributed on different Cloud Servers and preserved to protect user privacy information.This method uses encryption side
Method and the cloudy storage of fragmentation information are combined, and substantially increase the safety of user kernel information, for protection privacy of user letter
Breath tool is very helpful.
