A method, device and storage device for detecting and preventing end-to-end network data bad points

Abstract

The invention provides a method and a device for detecting and preventing end-to-end network data bad points, and a storage device thereof. The method comprises: obtaining correct root information; obtaining seed files; establishing communication relations with a source device detecting and preventing end-to-end network data bad points; setting an initial position and an end position of network data; calculating a hash value of the network data; feeding the hash value of the network data back to one device detecting and preventing end-to-end network data bad points; according to the obtained hash value, determining alternative source devices detecting and preventing end-to-end network data bad points; determining all the alternative source devices detecting and preventing end-to-end network data bad points; determining the source device detecting and preventing end-to-end network data bad points, the device providing network data; and detecting existence of the bad points. Provided are a device for detecting and preventing end-to-end network data bad point and a storage device thereof, and a method for detecting and preventing end-to-end network data bad points. The method and the device can effectively prevent and detect false network data which may occur in a network data transmission process, so as to prevent waste of large quantity of network resources.

Description

technical field [0001] The invention relates to the field of network security, in particular to a method for detecting and preventing bad points in end-to-end network data [0002] methods, devices and their storage devices. Background technique [0003] Each terminal in the end-to-end network is in a peer-to-peer position. When downloading network data, each client plays the dual role of uploader and downloader at the same time, that is, each terminal downloads shared files from multiple terminals at the same time, and shares the data it has downloaded to other terminals for simultaneous downloading. This method can speed up the downloading speed of network data. However, if a malicious terminal shares false network information (that is, a bad point), some terminals downloading from the malicious terminal will download false network information, thereby failing to complete the download of complete network information. In serious cases, a small amount of malicious termina...

Problems solved by technology

However, if a malicious terminal shares false network information (that is, a bad point), it will cause some terminals that download from the malicious terminal to download false network information, so that the download of complete network information cannot be completed.

In serious cases, a small amount of malicious terminals will cause a lot of waste of network resources
