Embodiment 1

[0133] In Embodiment 1 of the present invention, the process of writing the client file to the data server and reading the client file from the data server is introduced.

[0134] Step A1, the name server 10 receives the registration message containing username A, key version 1 and key 1 sent by the client, and stores the username A, key version 1 and key 1 in the form of a list in the database Correspondence;

[0135] Step A2, the name server 10 receives the new key version request message containing the user name A, key version 2 and key 2 sent by the client, and stores the user name A, key version 2 and key 2 in the database corresponding relationship;

[0136] Step A3, the name server 10 receives the write request message sent by the client and includes the username A, the key version 1, and the name and size of the file M;

[0137] Wherein, after receiving the writing request message sent by the client, the name server 10 stores the corresponding relationship between th...

Abstract

The invention relates to the technical field of data communication, in particular to a data transmission method and system. The data transmission method and system are used for solving the problem that the secrecy degree of a data server for client files is low. The data transmission method includes that receiving a write-in request message with user name, file name and file size from a client; confirming an encryption key, a division strategy and the corresponding relationship between each data block name and the data server according to the write-in request message and feeding back; enabling the client to send the encryption key, and the data and names of the divided data blocks to the corresponding data server to perform encryption storage; receiving a read request message with user name and file name from the client; confirming a decryption key and the corresponding relationship between the name of each data block of the file and the data server according to the read request message and feeding back to enable the client to send the decryption key and the names of the data blocks to the corresponding data server to obtain the data of the corresponding data blocks performed with decryption.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a data transmission method and system. Background technique [0002] HDFS (Hadoop Distributed File System, Hadoop Distributed File System) has the characteristics of high fault tolerance, high transmission rate and can be deployed on low-cost hardware, and is suitable for applications with very large data sets. HDFS includes a name node (NameNode) and multiple data nodes (DataNode), where the server containing the name node is the name server, and the server containing the data node is the data server. At present, the interaction between the client and the name server and the data server mainly includes the client writing files to the data server and the client reading files from the data server, which will be introduced separately below. [0003] Among them, the current process of the client writing files to the data server includes: [0004] Step A1, the client sen...
