Specific embodiment
Below in conjunction with attached drawing, a specific embodiment of the invention is described in further detail, so that technical solution of the present invention is more
It should be readily appreciated that and grasp.
Shown in referring to Fig.1, a kind of data leakage prevention method for being kept in technology based on data is provided with and is connected by several terminals
The local area network of composition, the local area network are configured with a central server 3, and the central server 3 connects the local area network
Each terminal in network, for storing data configured with memory module 10, the memory module 10 is by several for each terminal
Section 110 is stored to form, the present invention first is for the data storage in local area network, and data storage includes two positions, and one
The position for the terminal that data are located at, the other is data be located at which storage section 110 position, and it should be noted that
Firstly the need of marking off an independent memory module 10 from terminal, and memory module 10 is divided into several storage sections
110, storage 110 size of section is identical, and similarly needs to guarantee the size of each be-encrypted data and be less than the appearance of memory space
Amount.Specifically includes the following steps:
Data processing step a1, using the terminal where pending data as initial terminal 1, at the first Encryption Algorithm encryption band
Data are managed to generate the first encrypted cipher text and the corresponding first key of the first encrypted cipher text, into data configuration step a2；
It is that data are handled first, so that it may encrypted data are obtained, and the first encrypted cipher text can only pass through initial terminal 1
Could decrypt, that is to say, that no matter the first encrypted cipher text be sent to where, the right to use still falls within initial terminal 1,
In this way it is prevented that leaking data.
Data configuration step a2 configures the first refresh time and the second refresh time for first encrypted cipher text, into
Enter and refreshes temporary step a3；It then corresponds to each first encrypted cipher text and configures the first refresh time and the second refresh time, institute
State the second refresh time when 5-20 times of duration of a length of first refresh time.
Refresh temporary step a3, using the terminal where first encrypted cipher text as link terminal 2, including the first temporary step
Rapid a31, pointer encrypting step a32, the second temporary step a33 and address encryption step a34；It is walked as core of the invention
Suddenly, it is described in detail, for a corresponding encrypted cipher text, the terminal where defining it is link terminal 2, such as link terminal at this time
2B receives the encrypted cipher text.It should be noted that being continuous for refreshing corresponding first encrypted cipher text of temporary step a3
Repeat to execute, is triggered according to the time actual time, rather than triggered according to sequence of steps.
First temporary step a31 was configured with for the first cumulative time, when the first cumulative time reaching the first refresh time,
In the storage section 110 that the memory module 10 of link terminal 2 has generated at random to store first encrypted cipher text, and
The storage pointer information in the storage section 110 is obtained, the storage pointer information is directed toward the memory space, resetting described first
Cumulative time, into pointer encrypting step a32；Cumulative time obtains according to the real time, and can be received with link terminal 2
One encrypted cipher text is initial time, and such as the first refresh time is set as 60 seconds, that is to say, that was then added every 60 seconds for first
Ciphertext changes a memory space, in another embodiment, when first encrypted cipher text is stored into the storage section 110
Before, first encrypted cipher text is encrypted to obtain the first temporary encrypted cipher text by the first temporary Encryption Algorithm；When described first
Before temporary encrypted cipher text is removed from the storage section 110, add by the way that the first temporary decipherment algorithm decryption described first is temporary
Ciphertext is to obtain the first encrypted cipher text.Namely deposit and taking-up carry out primary encryption and decryption step respectively every time, improve
Information Security, and the information that pointer information is unique available position to storage section 110 is stored, as long as so initial
Terminal 1 get the address of link terminal 2 and get storage pointer information position be obtained with the first encrypted cipher text,
To carry out using.The data format phase of the first corresponding encrypted cipher text of the data format of the first temporary encrypted cipher text
Together.
Pointer encrypting step a32 encrypts the storage pointer information by the second Encryption Algorithm to generate pointer ciphertext letter
Breath and corresponding pointer key, save the pointer key, the pointer cipher-text information are sent to central server 3；And
Pointer encrypting step a32 is to be encrypted by the second Encryption Algorithm to storage pointer information, so, this location information
It needs just to can be carried out acquisition by pointer key.And so if initial terminal 1 needs to obtain storage pointer information, it is necessary to
To pointer cipher-text information and corresponding pointer key, and pointer cipher-text information is managed collectively in central server 3, each
Link terminal 2 does not retain pointer cipher-text information, and pointer key is then saved in corresponding link terminal 2, so, always just
End 1 needs to transmit a request to central server 3, and central server 3 finds corresponding link terminal 2, acquisition pair after receiving request
The pointer key answered, obtains storage pointer information, and such initial terminal 1 could complete the acquisition of the first encrypted cipher text, more pacify
It is complete reliable.In the pointer encrypting step a32, when the central server 3 receives a new pointer from same link terminal 2
When cipher-text information, the original pointer cipher-text information of link terminal 2 is deleted.In the pointer encrypting step a32, when the relaying
When terminal 2 generates a new pointer key, the original pointer key of link terminal 2 is deleted.
Second temporary step a33 configures the second cumulative time, when the second cumulative time reaching the second refresh time, root
A destination address is generated at random according to the routing table at the place of link terminal 2, and first encrypted cipher text is sent to the destination
Terminal where location, and second cumulative time is reset, into address encryption step a34；And the step is to count
According to sending, so the second cumulative time is accumulative according to the real time, such as is set as 5 minutes by configuring for the second cumulative time,
When the time reaching 5 minutes, so that it may it is sent to next terminal, and destination address is random according to 2 routing table of link terminal
It generates, has not regulation, can not track.The second temporary step a33 further includes, when a link terminal 2 receives described
When one encrypted cipher text, first encrypted cipher text is encrypted to obtain the second temporary encrypted cipher text by the second temporary Encryption Algorithm；
When a link terminal 2 sends the second temporary encrypted cipher text, it is temporary that described second is decrypted by the second temporary decipherment algorithm
Encrypted cipher text is to obtain the first encrypted cipher text.The data format of the temporary encrypted cipher text of described second and first encrypted cipher text
It is identical.So, reliability and safety are improved.
Address encryption step a34, the destination address is encrypted by third Encryption Algorithm with generate address cipher-text information with
And corresponding address key, the address cipher-text information is sent to corresponding link terminal 2, address key is sent to correspondence
Initial terminal 1.The setting of address encryption step a34, in order to encryption address, and address key is sent to just always
End 1, address cipher-text information is sent to corresponding link terminal 2, that is to say, that a corresponding data X, by A-B-C-D-E
Terminal, initial terminal 1A only has the address cipher-text information of B, but initial terminal 1 has all address keys, so can
To obtain the address of B, and B has the address cipher-text information of C, and is fed back to obtain the address of C according to B, thus successively until obtaining
The position of first encryption data sends to central server 3 and requests and obtain corresponding pointer storage information, to obtain correspondence
The first encryption data.In another embodiment, the address encryption step a34 is also configured with benchmark migration number, corresponding
One first encrypted cipher text is provided with actual migration number, whenever executing actual migration described in the primary address encryption step a34
Number increases a unit, when the actual migration number is more than benchmark migration number, by the address cipher-text information
It is sent to corresponding initial terminal 1.And it should be noted that is for a long time if constantly repeating data transmission
The data transmission range of formation increases, and data efficiency is called to reduce, so one numerical value of configuration, such as benchmark migration
Number is set as 10 times.And after being sent when 10 times, initial terminal 1 can be obtained by current position, that is to say, that pervious
It is invalid for address key and address cipher-text information, reduces data volume.
Certainly, above is representative instance of the invention, and in addition to this, the present invention can also have other a variety of specific implementations
Mode, all technical solutions formed using equivalent substitution or equivalent transformation, is all fallen within the scope of protection of present invention.
