Method and system for downloading executable file securely

Abstract

The invention provides a method and a system for downloading an executable file securely. The method comprises the following steps that: a client makes a security analysis request on the executable file to a security supervision server; the security supervision server performs security analysis on the executable file by using a uniform resource locator (URL) and a feature code of the executable file to generate a security analysis result and returns the security analysis result to the client; and the client acquires security information of the executable file according to the security analysis result. By the method, a user can learn security threat and hidden danger of the file before downloading or installing the executable file so as to avoid risk in advance, and compared with the method that the downloaded software is securely scanned by mobile phone security software, the method of the invention avoids the downloading of the executable file with security danger and saves terminal traffic and cost.

Description

technical field [0001] The invention relates to the field of security defense for downloading files through a network, and more specifically, relates to a method and system for safely downloading executable files. Background technique [0002] With the progress of society and the development of technology, people increasingly use mobile terminals to access the Internet in a wireless manner to obtain information, including information browsing and file downloading. However, with the wide spread of network information, network security issues are becoming more and more severe, especially many executable files. Now viruses and Trojan horses not only steal passwords and account numbers to slow down the system, but also infect executable files and delete ghost backups. [0003] Especially for mobile terminals such as mobile phones, due to the limitation of hardware resources of the terminal itself, it is necessary to download many executable files in the process of accessing the ...

Problems solved by technology

Although this "online virus inspection" can enable users to understand the security of the downloaded software before installing the software, help users discover "wolves in sheep's clothing" in time, and avoid losses caused by being tricked into installing; The method requires the user to upload the downloaded installation file to the service provider’s virus screening server, which not only consumes the download traffic, but also the user’s upload traffic. The online virus screening will also increase the GPRS traffic of the mobile terminal and reduce the execution time. File download and installation efficiency
