Abstract

The invention discloses a data access method and equipment adopting the same. In the data access method disclosed by the invention, metadata information is encryption information; when accessing a storage server according to the metadata information, a client side needs to acquire a metadata key according to user identification, and obtain the metadata information by decrypting the encryption information according to the key, therefore, an unauthorized client side can not obtain the metadata key according to the user identification, further the metadata information can not be decrypted, and then the phenomenon that an unauthorized client side accesses a metadata server to acquire metadata information and then accesses the storage server through the metadata information can be avoided.

Description

technical field [0001] The invention relates to the technical field of data processing, and more specifically, to a data access method and a device using the data access method. Background technique [0002] Many existing distributed file systems adopt the system structure with metadata server, such as figure 1 As shown, it includes a client 101, a metadata server 102, and a storage server 103, wherein: the metadata server 102 is connected with a metadata storage device for storing the relevant information of the file system and the metadata information of the file; the storage server 103 is connected with The data storage device is used to store the data information of the file. [0003] Specifically, the file system data access process of this structure is: the client 101 sends a data distribution query request to the metadata server 102; the metadata server 102 accesses the metadata storage device according to the data distribution query request, acquires metadata inform...
