Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0039] With the development of big data, the server is usually configured with a disk array, the server stores the data to be stored in the disk array, and reads the required data from the disk array. A disk array is usually composed of a plurality of hard disks. In order to realize data reading and writing and data security, the disk array provides logical storage units according to predetermin...

Abstract

A method and apparatus for encrypting data stored in a disk array belong to the field of storage encryption technology. The encryption method comprises the steps of receiving data frames sent from a server, analyzing the data frames, and obtaining at least one group of data to be stored in a disk array; for each set of data to be stored in the disk array, obtaining a disk array number, a LUN identification and an LBA corresponding to the data; determining adjustment values corresponding to data according to disk array numbers, LUN identification and the first two or all of LBA; obtaining theencryption key corresponding to the LUN identifier, adjusting the encryption key by the adjustment value, encrypting the data by the adjusted encryption key, and storing the encrypted ciphertext datain the disk array. The application enables each group of data stored in the LBA to have a unique encryption key, thereby increasing the difficulty of deciphering the ciphertext data and ensuring the security of the ciphertext data in the disk array.

Description

technical field [0001] The invention belongs to the technical field of storage encryption, and relates to an encryption method and device for encrypting data stored in a disk array. Background technique [0002] With the development of information technology, the speed of data transmission and data exchange has increased geometrically. While data is being transmitted at a high speed, data transmission security has become the primary problem to be solved by many important departments. [0003] At present, the storage of big data usually requires a disk array. In order to ensure the security of the data in the disk array, the gateway before the server and the disk array usually encrypts the data to be stored in the disk array, and encrypts the encrypted data. File data is stored in the disk array. The traditional encryption method is to use the encryption key to uniformly encrypt the plaintext data to be stored in the disk array. Once this encryption method is deciphered and...
