Abstract

The invention discloses a data transmission method and device, and the method comprises the steps that a request node initiates a plurality of downloading requests to a target downloading node, the plurality of downloading requests comprise a real target downloading request, and the target downloading request is used for requesting to download target data; other downloading requests except the target downloading request in the plurality of downloading requests are virtual downloading requests; and the request node receives feedback data sent by the target downloading node according to the M downloading requests, and further obtains target data according to the feedback data. According to the method provided by the invention, the target downloading request is hidden in the plurality of downloading requests through concurrence of the plurality of downloading requests, so that the target downloading node cannot know the real demand of the requesting node, the security of data transmission in an untrusted network environment can be improved, and the privacy of a user is protected to a certain extent.

Description

technical field [0001] The present application relates to the field of data transmission, in particular to a data transmission method and device. Background technique [0002] With the popularity of high-speed Internet and the improvement of computing power and storage capacity of personal computers, Internet users can share files through the network. For example, Internet users can use a large number of storage nodes scattered in the Internet to distribute storage data to all network nodes. Each network node can use the idle storage space to perform storage tasks, so as to achieve the purpose of mass storage. [0003] When the user needs to download resources, he can initiate a download request to the download node, and then execute the resource download. However, during this process, malicious download nodes can spy on the resources requested by the user, thereby spying on the privacy of the user. [0004] In order to solve the above problems, the existing technology us...
