Design And Implementation Of Node Information Analysis System For Anonymous Network Tor

Along with progress of epoch,Internet technology was rapidly developed,it has been integrated into every aspect of human’s live,increments of cyber threats are receiving widespread attention,cyber security has become the focus of attention.Anonymous system Tor is a low-latency instant communication software,using three layers’ proxy to access the network,keeping visitors’ IP and websites from being stolen,effectively guaranteeing user anonymity.But,due to the anonymity of the Tor network,it also leads to the use of Tor to access and release illegal information,it’s difficult for the security department to prevent and control.This article aims to design a Tor node information analysis system,and proposes a statistical analysis solution for Tor network nodes,to help users perform Tor network node information analysis,to query real node data in Tor network,to analyze node/16 network segment,to analyze node families,administrators can discover node family,manage node data and user management.This article starts from the perspective of web system development,firstly researching on Tor network and its familiarity,analyzing family data,and introducing related technology research used in system development.Tor node system adopts B/S architecture,using Spring MVC to separate models,views and controllers based on Java language,using MySQL database to store user and node related information,using MyBatis for data mapping.Secondly,analyzing the requirement of system,including functional and non-functional requirements,dividing user roles,the main function modules of ordinary users are query node information module,analog node selection module,various node data statistics modules,and the main function modules of administrators are node information management module,node family module,user management module.Users can query all Tor node related information,simulate node selection,analyze links,obtain node/16 network segment,contact information,and family information.Designing and implementing specific functional modules of the system,and finally test the system to complete the system development cycle.
