利用JAVA编程实现网络安全通信

Realizing Network Safety Communication by Applying JAVA Programming

网络安全涉及面极广，而数据传输的准确性、机密数据的安全性是计算机网络安全通信的关键．在ＩＮＴＥＲＮＥＴ网络环境下，讨论利用ＪＡＶＡ语言实现网络安全通信的编程特性．着重说明基于ＴＣＰ／ＩＰ协议的ＪＡＶＡ．Ｎｅｔ．Ｓｏｃｋｅｔ类库的通信机制，以及客户机／服务器工作模式．给出实现ＪＣＰ系统的文件传送流程图和多线程结构图，列出用户服务线程的部分源代码．同时。

The crux of safety communication of computer network lies in the accuracy of data transmission and the security of confidential data.On the realization of network safety communication in the Internet network environment,the authors discuss the characteristics of programming in JAVA laguage.Emphasis is placed on the communication mechanism of JAVA.Net.Socket class library based on TCP/IP protocol;and on file transport and block diagram of multi threading of JJCP system realizing in client/server model,with a list of parts of source codes of user service threading.A detailed analysis is aimed at the data cryptography.
