If d=1,2 ..., (k/s)-1, then T (d)=s/ (k*d);
If d=(k/s), then T (d)=s*ln (s/f)/k;
If d=(k/s)+1 ..., k, then T (d)=0.
In more than representing, k represents file institute is divided into the integer being less than n in n code element, and d represents the integer being less than k, and c, f are constants, is preferably, c>0.
After having had this distribution, need to carry out coding encrypting to file to be stored.Specifically: the file after encryption is F ', it is made up of the message of N+1 encryption, and its form is: F '=(e
1, e
2..., e
n+1).E
id
imessage after encoded encryption, the message of wherein encrypting
wherein I is initialization vector, E
ki () represents the cryptographic algorithm based on key, preferably AES.And e
n+1all encrypting messages e before expression
1, e
2..., e
nkey K and the XOR function of Hash, that is:
wherein H (i) is cryptographic algorithm, such as SHA; Wherein K is the key of random selecting from block block cipher.
As mentioned above, store file to be stored, this step can adopt various storage mode known in the art and storage medium/carrier.Fig. 2 illustrates the process flow diagram stored file to be stored.Preferably, the present invention adopts following specific step: the data of the source file of binary mode are carried out packet transaction, to form identical data group; According to the order of data group in source file, corresponding two-dimensional coordinate is produced to form set of coordinates to each data group; Set of coordinates is stored on a storage device.About memory device, preferably tangible non-transitory computer-readable medium, such as but not limited to the semiconductor memory of floppy disk, hard disk, CD-ROM dish and MO (magnetic-light) dish, DVD-ROM dish, DVD-RAM or such as flash memory and so on.
The process flow diagram that Fig. 3 diagram is decoded to file to be stored and recovered.The step of decoding to file to be stored and recover is as follows: by from symbol decoding message e
iand the F ' that decodes; By using F '=(e
1, e
