[Abstract]:With the continuous development of IT industry and network communication technology in today's society, communication through the Internet has become an indispensable part of the communication and communication of people's life and work. Many people have become accustomed to using these tools for daily learning and work contact. However, in many cases, the employees are not allowed to obtain permission. The use of personal communication tools at will brings great security and efficiency to the enterprise's own network, especially for enterprises with high secrecy, the ordinary LAN chat software can not meet its requirements, and the employees usually use communication tools for non working chatting, so that the efficiency of work has been reduced again and again. Therefore, In this situation, it is very important for a large number of small and medium enterprises to ensure the timeliness of the secure communication data and the safety and reliability of the information storage and communication process. It is urgent to design and implement a feasible, convenient and secure internal instant communication system for enterprises. The paper adopts the method of software engineering. Design enterprise internal network security communication system, focusing on the related technology, security algorithm, requirement analysis, overall design, detailed design, database design and system implementation and testing of enterprise internal network security communication system. After detailed analysis and Research on the requirements of the enterprise internal network security communication system, the use case diagram is carried out. The use case specification description table describes the functional requirements of the communication system. At the same time, it describes the non functional requirements of the intranet secure communication system from the perspective of the software system products. In the overall design and detailed design stage of the enterprise internal network security communication system, the system network topology map, the system function structure diagram and the various functions are used. The class diagram and time sequence diagram display the physical structure and function module of the enterprise internal network security communication system. In the database design stage, the scientific and rational database modeling and analysis are carried out on each function module of the enterprise internal network security communication system, and the corresponding E-R diagram and database table are designed. Finally, the enterprise inner network security is designed. The main modules of the whole communication system are tested and tested, and the corresponding interface and implementation code are given. The main functions of the system are realized, and the system's security and shortcut are guaranteed. The enterprise internal network security communication system is composed of three parts, the server side, the data base server and the client. At the same time, the need for the basic functions of high security enterprises to the communication system. At the same time, the distributed deployment idea is adopted, the server, client and data end are deployed in distributed deployment to realize the function of locating storage information and sharing storage load. The client communicates according to the server, and the server end module mainly implements the user form. State management, login authentication and message processing; the database server module mainly realizes the record of operation information and state after user login; the client module mainly realizes the functions of user login, state operation, instant chat, good friend management, file transfer, conference management, file sharing, and address book management. This system is based on Microsoft .NET Framework, using Visual Studio 2012 as the development tool of the system program; using three tier C/S and WCF communication development platform to design the system architecture, and use the ADO interface to access MYSQL database design data management module; use the suite interface SOCKET to connect the server to the client, and use multithreading to satisfy the multiuser. At the same time, the TCP and UDP protocols are used as the transport layer protocol to facilitate the one to one or more communication between employees. The intranet secure communication system builds a smooth communication platform for employees in the LAN, and realizes the basic function of the office interaction, and does not only allow employees to communicate easily and communicate easily. It also greatly meets the security needs of the enterprise.
