Design And Implementation Of A Phishing Website Detection System Based On Smart Router

With the booming development of the mobile Internet,phishing attacks are becoming increasingly rampant,posing a serious threat to the daily lives of Internet users.Most of the current defence strategies against phishing attacks are based on browser plug-ins,but for the more covert phishing attacks,browser plug-ins on mobile cannot intercept as effectively as browser plug-ins on PC.Nowadays,smart routers play an important role in the Internet era and are able to access more network packets compared to traditional browser plug-ins.If phishing attacks can be defended based on smart routers,the privacy and information security of Internet users will be more efficiently protected,so phishing website detection methods based on smart routers are of great research significance.This paper conducts research on phishing website detection methods based on smart routers,and the main work is as follows:(1)Requirement analysis and design of phishing website detection system based on smart routers.Based on the analysis of system requirements,a parallel defence strategy is designed for the smart router side based on OpenWrt,including four modules of feature extraction,server interaction,marker bit modification and interception judgment;a module for colour image conversion of website feature files and a module for improved capsule network model detection are designed for the server side.(2)Research on the detection method of phishing websites based on the improved capsule network model.A phishing website detection method based on the improved capsule network model is proposed,which consists of two parts: colour image conversion of website feature files and detection based on the improved capsule network model Graph Att-Caps.The method is experimented with a large number of data sets and compared with the ordinary capsule network model.The experimental results show that the method based on the Graph Att-Caps model has a high accuracy rate.(3)Implementation and testing of a phishing website detection system based on an intelligent router.Based on the previous requirement analysis and design,the phishing website detection system based on smart router is implemented,the development environment of the system is introduced,and the process of implementing each functional module of the system and the related core code are introduced respectively.Finally,the system is tested and the test results show that the system has good feasibility and stability.
