Embodiment Construction

[0065] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0066] The data processing method provided by the embodiment of this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the CDN node 104 through the network, and the CDN node 104 is connected to the source server 106, and the source server 106 sends the file to be stored to the CDN node 104. The terminal 102 initiates a data read request to the CDN node 104, and the CDN node 104 receives the data read request sent by the terminal; according to the storage file corresponding to the data read requ...

Abstract

The invention relates to a data processing method and device, computer equipment and a storage medium. The method comprises the following steps: enabling a terminal to send a data reading request; according to a storage file corresponding to the data reading request, selecting a verification data block through a random algorithm; acquiring a target hash tree corresponding to the storage file, wherein the target hash tree comprises data from a layer where a root node is located to an M-th layer, M is a positive integer, a first hash value is stored in the root node, and each leaf node corresponds to a data block of the storage file; calculating a second hash value corresponding to a root node of the target hash tree according to the verification data block and the target hash tree; and if the first hash value is the same as the second hash value, returning data corresponding to the data reading request in the storage file to the terminal. According to the method, the authenticity of the storage file is verified by randomly selecting the verification data block, so that the storage pressure of the CDN node can be reduced, the verification calculation complexity is reduced, and the verification efficiency of the security of the data requested to be read by a user is greatly improved.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data processing method, device, computer equipment and storage medium. Background technique [0002] With the rapid development of Content Delivery Network (CDN), more and more users obtain file data of source servers through CDN. CDN is an intelligent virtual network built on the basis of the existing network. It is a distributed network composed of edge node server groups distributed in different regions. Through the load balancing, content distribution, scheduling and other functional modules of the central platform, users can reach the nearest Obtain the desired content, reduce network congestion, and improve user access response speed and hit rate. CDN is widely used and supports content acceleration in various industries and scenarios, such as small picture files, large file downloads, video and audio on demand, live streaming media, site-wide acceleration...
