基于数字校园即时消息发布的设计模型及实现方法

Design and Implementation of Instant Message Based on Digital Campus Network

为了解决数字校园信息应用部门分散的、孤立的消息发布以及消息传递的及时性问题,提出了校园网即时消息发布的设计模型。首先基于数字签名技术应用ActiveX组件下载安装了即时消息通讯的客户端;然后通过服务器端软件读取共享Web数据库中已审核的具有不同权限和特征的消息实现了消息的即时发布,实验了基于自定义对称加密算法在C/S两端进行消息传递的方法;最后实现了向校园网客户端进行广播或者组播方式的消息实时发布。系统也讨论了其运行组织方式。

In order to solve isolated and scattered news and timeliness problem in digital campus network, proposed the instant message design modal, the first, ActiveX component is used to download and install the instant message communication client software based on digital signature technology. And, read the audited message with different powers and characteristics of web - sharing datebase achieve instant message release by server - side software. Experiment the methods of instant messaging between server and client based on custom symmetric encryption algorithm. Finally, achieve campus network elient＇s instant news release by the broadcast or multicast way.
