Problems solved by technology

However, the distributed file system's native encrypted transmission storage support is not enough
When providing external services such as off-site Internet data center (Internet data center, IDC), storage level leasing, etc., the distributed file system has the disadvantage of insufficient data security
In addition, the distributed file system is based on a custom distributed remote procedure call (Remote Procedure Call, RPC) protocol communication based on Transmission Control Protocol / Internet Protocol (TCP / IP), which cannot provide a good Transport Layer Security / Secure Sockets Layer (Transport Layer Security / Secure Sockets Layer, SSL / TLS) encryption and decryption support

Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them.

[0017] figure 1 A block diagram schematically illustrating the architecture of a distributed file system. The distributed file system usually includes a management node and at least one storage node (storage nodes 1, 2, . . . n). The management node is used to manage the storage of files on the storage node and the access of clients to files. The storage nodes are used to store files. When the client needs to store a file, it sends a write request to the management node, and the management node allocates a specific storage node to store the file, and notifies the client of the address of the allocated storage node through a response, and then the clien...

Abstract

The invention provides a method and device for transmitting data. The method and device for transmitting data is applicable to distributed type file systems. The method for transmitting data includes: a client side is used for confirming storage nodes for storing data by interacting with management nodes; the client side generates secret keys for encrypting the data, the secret keys are used for encrypting the data, and the encrypted data are transmitted the storage nodes for storing the data; the secret keys are transmitted to storage nodes through a secret key transmission step which includes: the client side encrypts the secret keys to obtain the encrypted secret keys and transmits the encrypted secret keys to the management nodes; and the management node decrypts the encrypted secret keys to obtain the secret keys and transmits the secret keys to the storage nodes for storing the data. By means of the technical scheme, safety of the data in transmission can be improved, and simultaneously good data transmission performance can be kept.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a method and device for transmitting data. Background technique [0002] With the development of communication technology and the widespread use of electronic equipment, it is increasingly necessary to transmit and store massive amounts of data. To this end, a distributed file system (Distributed File System, DFS) is proposed. A distributed file system usually includes a management node and at least one storage node. The management node performs unified management, such as managing file storage on the storage node and client access to files. The distributed file system has the advantages of centralized access, simplified operation, and improved file access efficiency. [0003] Hadoop is a set of software infrastructure for large-scale Internet applications dedicated to massive data processing. It is a framework designed to complete distributed applications on ...
