[0055] Please refer to figure 1 , is a schematic diagram of the interaction between the blockchain system 10 and the electronic device 20 provided by the embodiment of the present invention. The blockchain system 10 provided by the present invention and the electronic device 20 can establish a communication connection through a network for data interaction. The network can be, but is not limited to, a wired network or a wireless network. In this embodiment, the block chain system 10 can be used to identify and judge whether the file (including the installation file of the application program) to be downloaded by the electronic device 20 is safe, and only push the file to be downloaded to the electronic device 20 when the file is safe. To prevent the Trojan virus from being implanted into the files to be downloaded, thereby improving the network security of the electronic device 20 .

Abstract

The invention provides a network security protection method and a network security protection device, which relate to the technical field of network security. According to the network security protection method, a download request sent by an electronic device is received; prestored first key information which corresponds to the electronic device is compared with second key information carried by the download request; when the first key information is the same as the second key information, a to-be-downloaded file which corresponds to the download request is determined; whether a list which corresponds to the to-be-downloaded file is in a prestored white list or not is judged; if the list of the to-be-downloaded file is in the prestored white list, whether a first Hash value of the to-be-downloaded file is the same as a prestored second Hash value or not is judged; and if the first Hash value is the same as the second Hash value, the to-be-downloaded file is downloaded into the electronic device. On one hand, the invention can help prevent Trojan from getting into the electronic device by the way of implantation, and on the other hand, the invention can help improve the network security of the electronic device, and prevent the leakage of private information.

Description

technical field [0001] The present invention relates to the technical field of network security, in particular to a network security protection method and device. Background technique [0002] With the development of communication technology, the network has been integrated into people's daily life. For example, people often use mobile devices such as smartphones and tablets to access the Internet through wireless networks. People also use mobile devices for shopping, payment, social interaction, etc., and their property and private information are stored in the mobile devices. In addition, with the gradual popularization of the Internet of Things, many smart home devices can be connected to mobile devices through wireless routers, and people can check the device status of smart home devices and control these devices by opening the mobile application. In the prior art, users usually implement information security protection by setting a login password. However, this type o...
