Problems solved by technology

Since there are many viruses on the WEB side at present, the virus file will be disguised as the same file name as the sub-SWF file, so the main SWF file may be loaded as a virus SWF file, thus poisoning the client computer
Or for some sub-SWF files are modified during network transmission, then loading such modified or undownloaded SWF will cause a program error

Abstract

The embodiment of the invention discloses a method and a device for safely loading a Flash file. The method of the embodiment comprises the steps of after downloading a main Flash file in a target Flash program, downloading a target Flash sub-file from a server through the main Flash file; carrying out hash calculation on a first content in the target Flash sub-file to obtain a first hash value; sending a file name of the target Flash sub-file and the first hash value to the server; receiving a first comparison result sent by the server; and when the first comparison result is correct, loading the target Flash sub-file in the target Flash program. According to the embodiment, when the Flash program loads the Flash sub-file, hash verification is firstly carried out on the Flash sub-file, the Flash sub-file is reloaded after the authenticity of the Flash sub-file is determined, a virus Flash file is prevented from loading and the safety risk is reduced.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method and device for safely loading Flash files. Background technique [0002] At present, Flash is widely used in web design, web animation production and web video playback. Most video websites, including live broadcast websites, use Flash as their video player, and most web games are also developed using Flash. The specific file used by Flash is SWF (Shock Wave Flash) file. In a large-scale Flash program, multiple SWF files are usually written, and each SWF file completes some functions, which facilitates modular development. At the same time, the resource files used by SWF are usually placed in a separate SWF file. . First, the client will download a main SWF file, and the main SWF file will download other sub SWF files, and load the sub SWF files, so as to cooperate to complete the entire function. Because there are many viruses on the WEB side, the viru...
