Abstract

The invention provides a fault tolerance method, apparatus and system of file transmission in a cloud distribution network, and relates to the field of data transmission. The problems of low efficiency and high cost of the existing HTTPS anti-hijacking scheme are solved. The method comprises the following steps: sending, by a content node, a request to a superior node to request to download a target file; receiving the target file and feature information corresponding to the target file issued by the superior node; generating verification information corresponding to the target file; and whenthe verification information is inconsistent with the feature information, deleting the target file issued by the superior node. The technical scheme provided by the invention is applicable to the cloud distribution network, and an efficient fault tolerance mechanism that takes good user experience into consideration is achieved.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a fault-tolerant method, device and system for file transmission in a cloud distribution network. Background technique [0002] Generally speaking, traffic hijacking is a kind of Man-in-the-Middle Attack (MITM). In essence, the attacker sniffs and tampers the communication content between the two ends of the communication in order to insert data and obtain key information. Purpose of Information. At present, traffic hijacking on the Internet is basically realized by two methods: (1) Domain name hijacking: by hijacking the DNS resolution result of the domain name, the HTTP request is hijacked to a specific IP, so that the client and the attacker's server establish a TCP connection, rather than a direct connection to the target server, so that the attacker can steal or tamper with the content. In extreme cases, the attacker may even forge the target website page to carry out phis...
