一种基于网络的文件加密方法的研究与实现

摘要

Nowadays, the Internet has completely integrated into people ' s daily life and work, and it is greatly convenient for people to obtain and transmit information. In order to make data encryption to meet the needs of more application scenario, a network file encryption system is built in Visual Studio 2010 plat-form. The system uses C/S architecture, the client completes the function of user interface and user opera-tion, and the server implements specific encryption step. The system is applied to the application layer of the OSI reference model, with the end-to-end encryption. Files on the network are transmitted in the form of cipher text, thus to ensure the file security in the transmission process.%当今社会互联网已完全融入到人们的日常生活和工作当中，网络极大地方便了人们获取和传递信息。为了让数据加密适应网络时代更多应用场景的需求，在Visual Studio 2010平台上构建了一种网络文件加密系统，系统采用 C/S 架构，客户端完成用户界面和用户操作处理功能，服务端实现具体的加解密功能。系统应用于 OSI 参考模型的应用层上，采用了端到端的加密方式，文件在网络上以密文形式传输，确保了文件在传输过程中的安全性。
