Description
Technical field
The technology of the present patent application belongs to data transmission method field in computer network, particularly relates to as ensureing data
A kind of based on File Mapping encryption the document transmission method that efficiency in document transmission process and safety are proposed.
Background technology
Along with the development of network technology, increasing user begins through mobile network or the Internet connection is obtained from
The information that oneself needs.Transmission in the network information is carried out by data file, between different data files is according to user
Instruction be transmitted and receive.Along with transmitting being continuously increased and extending of data volume, the file data amount of transmission over networks becomes
Geometry multiple increases, along with mechanics of communication on the network bandwidth also constantly progressive, but gathering way of bandwidth far away can not be with
The speed that its transmitting data increases matches.For that purpose it is necessary to consider to try one's best in the case of keeping legacy data fileinfo
Reduce the file data amount of network transmission.File compression techniques is that one is very simple, direct reduces transmission file data amount
Mode.It solve uncompressed in the case of, document transmission method is simple traversal file, and is read out content one by one also
Encryption, is transmitted by TCP or udp protocol, and file is too much, and reading speed and enciphering rate all can be affected and even become
Slowly, if running into excessive file, memory usage too high can even result in internal memory and overflow, and occupies too many computer money
Source, the defect of inefficiency.
Another key issue of web document transfer is the safety of transmission file, if network data is cut by " hacker "
Take to the transmission of data with receive server and attack thus cause whole network paralysis and crack.For that purpose it is necessary to biography
Defeated data are encrypted, and various different encryption methods are arisen at the historic moment.
In order to overcome the wasting of resources in the transmission of existing file network and the relatively low defect of safe coefficient, the technical program profit
With file compression techniques, the file needing transmission is carried out high compression ratio compression according to file structure by compression algorithm, makes pressure
File after contracting is the least, thus speed when increasing substantially file transmission, simultaneously by file encryption algorithm, after compressing
File carry out binary system encryption, and upper transmitting file is to specified file server.
Summary of the invention
The technical scheme of the application is contemplated to solve: how (1) allows file transfer speed faster, meets multifile and sends
Demand, improves transmission speed；(2) system resource occupancy when reducing file encryption, improves resource utilization；(3) data are ensured
Safety in transmitting procedure, proposes a kind of document transmission method based on File Mapping encryption.The method includes that file sends
With two processes of reception；The step realizing file transmission process is: (1) compressing file to needing transmission；(2) literary composition after compression
Part carries out binary system encryption；(3) MD5 value the record of encryption file are calculated；(4) encryption file is uploaded to the file service specified
Device；(5) the JSON string returned the most afterwards is uploaded in parsing, and intercepts the URL of file download；(6) by the key of (2) step encryption,
(3) URL of the MD5 value of step and (5) step creates file message JSON string；(7) file message and JSON thereof are sent by HTTPS
String.File download receives the concretely comprising the following steps of process: (a) needs the client downloading file to receive message JSON to go here and there and resolve and obtain
Obtain the MD5 value of file, download URL, encryption key information；B () client starts to download file；C () completes school after file download
Test MD5 value；D () upper step starts to decipher file and carries out decompression process again and realize file download after verifying successfully.
Above-mentioned document transmission process is through file encryption algorithm, and the file after compression is carried out binary system encryption, and
Upper transmitting file, to specified file server, is gone here and there by the file content JSON returned, and parses correspondence in file server
URL, and by fileinfo and file MD5 value, encryption key generation file message JSON string, transmitted JSON by HTTPS
Being sent to recipient, recipient carries out Context resolution after receiving JSON string, downloads file by URL to specified file server,
Verified by MD5 value, verify and use corresponding key to be decrypted and decompression process by rear, complete whole file
Transmission.
Above-mentioned realize compressing file after file format be, rar, zip, tar, cab, uue, jar, iso, z, 7-zip,
The compressed file format of ace, lzh, arj, gzip, bz2, compression ratio is not less than 50%
For improving the efficiency of file transmission, multiple files through overcompression encryption are carried out in upload procedure and under compressed file
Parallel mode is all used to download during load.
The method of the present invention is transmitted by encrypting the data that the transmission of multiple files is converted to single file after compression, carries
The high efficiency of file transmission, it is achieved that the guarantee of transmission security.
Accompanying drawing explanation
Fig. 1 is to utilize technical scheme to carry out data transmission flow figure；
Fig. 2 is to utilize technical scheme to carry out data receiver flow chart.
Detailed description of the invention
For becoming apparent from technical solution of the present invention is described, it is introduced by specific embodiment below, if Fig. 1 is to utilize
Technical scheme carries out data transmission flow figure, as it can be seen, its process is: (1) compressing file to needing transmission；
(2) file after compression carries out binary system encryption；(3) MD5 value the record of encryption file are calculated；(4) encryption file is uploaded extremely
The file server specified；(5) the JSON string returned the most afterwards is uploaded in parsing, and intercepts the URL of file download；(6) by (2)
The key of step encryption, the URL of the MD5 value of (3) step and (5) step creates file message JSON string；(7) file is sent by HTTPS
Message and JSON string thereof.After compressed file after encryption uploads onto the server, when other users need download file time, carry out as
Lower process, as shown in Figure 2: (a) need download file client receive message JSON go here and there and resolve acquisition file MD5 value,
Download URL, encryption key information；B () client starts to download file；C () verifies MD5 value after completing file download；(d) upper step
Start to decipher file after verifying successfully to carry out decompression process again and realize file download.In the uploading of whole file, downloading process
In be both for compression after the less file of data volume operate, thus reduce the transmission requirement of network data, simultaneously
Compressed file is encrypted through MD5 method, also ensure that the safety in document transmission process.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in essence of the present invention
Any amendment, equivalent and the simple modifications etc. made in content, should be included within the scope of the present invention.
