Problems solved by technology

Although the above backup and recovery mechanism makes it difficult to lose data in the cluster, there is no perfect data encryption mechanism during data transmission
The communication between each node in the Hadoop cluster uses clear text transmission, and the information is easy to intercept

Abstract

The embodiment of the invention provides a communication method and device. The method is applied to a Hadoop client, and comprises the following steps: sending a first request message to a Hadoop server, wherein the first request message carries a password specification parameter, and the password specification parameter at least comprises an encryption algorithm supported by the Hadoop client; receiving a first response message of the Hadoop server for the first request message, wherein the first response message at least comprises a first preset digital certificate of the Hadoop server anda first encryption algorithm selected by the Hadoop server from the encryption algorithms; performing identity authentication on the Hadoop server according to the first preset digital certificate; and when the identity authentication is passed, generating a password specification according to the first encryption algorithm, and sending the password specification to the Hadoop server. According tothe embodiment of the invention, the encrypted transmission of the data in the Hadoop cluster is realized, and the data encryption technology is utilized to ensure that the data cannot be interceptedor eavesdropped in the transmission process on the network.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a communication method and device. Background technique [0002] Cloud Computing is a data processing and storage method that provides dynamically scalable virtualized resources through the Internet. With the rapid development of cloud computing, powerful computing and storage capabilities make it widely used in various fields. [0003] Data security is an important part of the cloud computing research field. At present, Hadoop is a widely used cloud computing method, and its two core modules are the distributed file system module (Hadoop DistributedFile System, HDFS) and the parallel computing module (Mapreduce) of large-scale data sets; among them, HDFS It is the storage module of Hadoop, which provides the underlying support of distributed storage for cloud computing systems, and has the characteristics of high fault tolerance and easy exp...
