Design And Implementation Of Tor-based File Transfer Management System

Along With the continuous innovation of contemporary Internet technology,more and more enterprises and institutions use Internet software to transmit confidential data.With the deepening and expansion of Internet applications,more and more security risks are brought to computer networks at the same time.This system aims to design and implement an anonymous and secure file transfer management system,which provides users with functions such as friend management,group management,anonymous chat,file transfer and so on.In the TOR network,users encrypt communication data at multiple layers with the help of anonymous communication technology,so that traffic monitoring cannot sniff out user data and user identity information,and maintain the anonymity and security of file transmission.With the help of encryption technology,it can ensure that only the target receiver can read and browse the communication content,so that the server or other monitoring services cannot obtain user data,and ensure the security of the data on the client and server.Use WebSocket and WebRTC technology to realize a cross-platform,high-performance,full-duplex file transfer management system with B/S and P2P architectures.The use of large file breakpoint continuance technology based on HTML5 to solve the problem of low transmission efficiency after transmission interruption.This paper first introduced the file transfer management system background and related technology overview,and then put forward the shortcomings of file transfer tools,sorting out and summarized the file transfer management system requirements.Then,according to the demand analysis of the overall design and detailed design of the system,and according to the design of the specific introduction of the realization of each function module of the system.Finally,the system is tested and the test effect is analyzed.Finally,according to the test results,the file transfer management system based on TOR meets the expectation and can provide an efficient and stable file transfer management service.
