Example Embodiment

[0044] Such as figure 1 As shown, a secure discrete storage method for sensitive data includes three parts: a client, a processing server, and N storage servers. First, the client client sends sensitive data to the processing server; second, the processing server randomly generates an N-bit length Key, and encrypts the sensitive data with the Key; third, the processing server splits the encrypted data into N copies Data block, and each bit of Key is spliced ​​to the end of the data block in turn; from the second time, the processing server will sequentially store N data blocks in the storage server, generate an index and store it in the processing server, and return the unique ID of the index to the client Finally, the client obtains sensitive data from the processing server, and the processing server requests data blocks from the storage server according to the index ID, and returns the sensitive data to the client after splitting, merging, and decrypting.

Abstract

The invention discloses a safe discrete storage method for sensitive data. A client side, a processing server side and N storage server sides are included. The method comprises the following steps: firstly, a client sends sensitive data to a processing server, the processing server randomly generates a Key with the length of N bits and and encrypts the sensitive data by using the Key; the processing server splits the encrypted data into N parts of data blocks, and splices each bit of the Key to the tail parts of the data blocks in sequence; the processing server side sequentially stores the Ndata blocks into a storage server, generates an index, stores the index into the processing server side, and returns the unique ID of the index to the client side; the client side obtains the sensitive data from the processing server side, the processing server side requests the data blocks from the storage server according to the index ID, the data blocks are divided, combined and decrypted and then returned to the client side, the storage safety of the sensitive data is improved, and the leakage risk in the transmission process is reduced.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a safe discrete storage method for sensitive data. Background technique [0002] In today's network environment, the data storage method is usually to encrypt the plaintext data and store it in a server or other media in a unified manner. However, most of the current mainstream encryption algorithms are public. Even if the data is encrypted, once the data is stolen, it is easy to be cracked. thereby causing losses. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a secure discrete storage method for sensitive data, which effectively improves the security of sensitive data storage and reduces the risk of data leakage. [0004] The present invention is realized by the following technical solutions: a safe discrete storage method for sensitive data, including three parts: a client, a processing se...
