Based On The Design And Realization Of The The Ice Middleware Secure File Transfer System

With the development and application of information technology, the people's armed police force academy in routine more and more use of IT systems. For instance,OA,student anagement system,financial management system,and so on. In the use of these systems will produce many types of data-files. These files are not only scattered in various systems but also transfer through various ways.For example,copy and paste share files between a-OS and b-OS,email,and instant message software,and so on. There is no uniform approach to unified security of these documents management.Likes these ways to transfer data-files is not safety and nice.The data-files is easy to loss or disclosure in transfer and access and lead to loss of the user.And people's armed police force academy is a rather special college,usually there are some data-files have certain level of confidentiality. Therefore,these data-files must be conducted through a secure access and transfer. In addition, with the popularity of the Internet.How to use internet to transfer these data-files safely and expediently is a problem.In the market, some foreign and domestic companies have launched their own products and solutions.For example,the company name Axway have the great solution which the name is SecureTransport.But such products like SecureTransport is high in price for sales and maintenance costs generally.So,these products are more suitable for some of the economic strength and IT enterprises with strong technical companies.In this thesis,we will use the ICE which is a open source communication middleware as the framework of communication and data transfer,and design a system that it is able to support the development of the TCP/IP protocol over an insecure network for secure and reliable data transmission(not only run on the intranet but also can run on the internet).The system can meet the demand for secure transmission of data-files. Meanwhile, the development of the system also needs in terms of cost and performance are a good compromise.Overview,this paper complete main some work as:1.Design and implementation of a communication and data-files transfer framework using ICE middleware. 2.Designed and implemented based on TCP/IP network security file transfer system.3.Using OpenSSL to provide for the secure file transfer system to encrypt and decrypt data.4.Design and implementation of the Secure File Transfer System's client and server programs.
