Abstract
The invention discloses a network distributed storage method based on hybrid encryption. The method comprises steps of: randomly splitting data; encrypting the split data in different ways; encrypting information, such as file sizes, numbers or the like, stored in an encrypting database by using an asymmetric algorithm; generating secret key files of the split data files by using a random number generator, encrypting the split data files by using different algorithms, and storing the encrypting algorithms of the data and secret key information; storing the split data files in a distributed server; performing asymmetric encryption on an index formed by the split file sizes, file storage locations, and the numbers, the data encrypting algorithms, and the secret key information; generating a public key pair and a private key pair, saving the private key pair in a key, and saving the public key pair in a system; and facilitating data recovery. The network distributed storage method based on hybrid encryption improves data security.
Description
Technical field
The present invention relates to a kind of network distribution type storage means based on Hybrid Encryption.
Background technology
A lot of distributed network memory device, just accomplishes the data integrity on surface in Information Security at present, and it is safe storage that the network storage equipment just had at last is known as, and in fact well can not solve the real safety of data.
Therefore, prior art needs to be improved.
Summary of the invention
The present invention, in order to solve the deficiencies in the prior art, provides a kind of network distribution type storage means based on Hybrid Encryption, effectively promotes the fail safe of data.
For solving the problems of the technologies described above, a kind of network distribution type storage means based on Hybrid Encryption that the embodiment of the present invention provides, adopts following technical scheme:
Based on a network distribution type storage means for Hybrid Encryption, it is characterized in that, comprise the steps:
S1: data are split at random;
S2: respectively different cipher mode encryptions is carried out to the data split out, be mainly symmetric encipherment algorithm aes algorithm and domestic SM1/4 algorithm;
S3: the file size of fractionation, file storage location and numbering cryptographic storage, in data, use asymmetric arithmetic to be encrypted the information such as the file size of database purchase and numbering;
S4: the data file split out generates key file by randomizer, the encryption each data file split out being carried out respectively to algorithms of different stores the cryptographic algorithm of each data and key information simultaneously;
S5: the data file after splitting is stored in distributed server;
S6: algorithm and the key information of the index that the file size of fractionation, file storage location and numbering are formed and each data encryption carry out asymmetric encryption;
S7: produce public, private key pair, preserve private key in key, preserve PKI in system;
