Cloud distribution network cache content verification method and device, network, storage medium and computing device

Abstract

The invention discloses a cloud distribution network cache content verification method and device, network, a storage medium and a computing device. The disclosed cloud distribution network cache content verification method comprises the following steps of generating first summary data on the basis of a cache content corresponding to a source station content; acquiring second summary data from a block chain; and verifying the consistency between the cache content and the source station content on the basis of the consistency between the first summary data and the second summary data, wherein the second summary data is generated based on the source station content. According to the technical scheme, the risk that data is tampered after a single centralized database is attacked is reduced.

Description

technical field [0001] The present invention relates to a content distribution network, in particular to a cloud distribution network cache content verification method, device, network, storage medium and computing equipment. Background technique [0002] The cloud distribution network is an important part of the Internet infrastructure. Its main function is to establish a cache server closer to the geographical location of the client to cache the website content, so as to achieve the effect of the client quickly obtaining resources. The website used to store the original content is generally called the origin site, which means the source of the content. A cache server or multiple cache servers at the same or close locations in the cloud distribution network can be used as a cloud distribution network node. Therefore, cloud distribution network nodes are generally widely distributed based on geographical location. [0003] From the perspective of network security, since the...
