WWW-客户/服务器中敏感数据安全传输的研究

WWW服务是Internet中最重要的服务之一,它的安全受到了越来越多的重视。本文从数据保密的角度对WWW-客户／服务器结构中敏感数据的传输问题进行了研究,提出了一种基于敏感数据自身及动态信息的加密方法。     

IP地址盗用监测系统

本文针对目前ＣＥＲＮＥＴ中普遍存在的合法ＩＰ地址被非法盗用,未分配ＩＰ地址的非法使用问题,实现一种简单可行的网络管理监测系统。该系统通过简单网络６管理协议,向网络设备的ＭＩＢ－２信息库请求当前所有活动主机的ＩＰＢ地址和所对应主机的ＭＡＣ地下信息,通过将ＩＰ地址与网卡以太网地址相绑定的方法,区分合法与非法用户,从而打击非法用户盗用ＩＰ地址,达到保护合法用户权益的目的。     

分布式智能光网络中主动的区段预恢复机制(英文)

The development of Internet brings a great challenge to the survivability of the supporting distributed intelligent optical networks. The emergence of Active-Fault-Alarm (AFA) technology makes it possible for the system to be aware of the incoming or possible fault in advance and to provide possibility to develop a more active restoration mechanism. On this base, an Active Segment Pre-Restoration (ASPR) mechanism for distributed optical network is proposed. ASPR allows establishing a Segment Pre-Restoration...     

Active network supports for mobile IP

The basic mobile IP protocol is difficult to implement on the traditional IP network and not flexible and efficient under certain conditions.For example,firewalls or boundary routers may drop packets sent by mobile nodes for security reasons.Traditional networking devices such as routers cannot dynamically load and unload extended services to achieve different qualities of services.In this paper,a new scheme of using the active network to support the mobile IP is presented.The Softnet,a prototype of active networks based on mobile agents,is introduced.The active network is characterized by the programmability of its intermediate nodes and therefore presents dynaic and flexible behaviors.Special services can be dynamically deployed onto the active nodes in the Softnet.This property is definitely required in implementing the mobile IP protocols.The SOftnet.This property is definitely required in implementing the mobile IP protocols.The Softnet.This property is definitely required in implementing the mobile IP protocols.The Softnet supports not only the basic mobile IP protocol but also other extended mobile IP protocols.Virtual networks for mobile IP services are dynamically formed by mobile agents in the Softnet to provide different qualities of services.

多播与多播应用程序开发

一、引言 随着网络规模的不断扩大,网络信息资源的迅速增加,网络传输负担将会逐渐提高,尤其是近今年来比较流行的视频会议和多媒体数据传输问题,它是将网络资源传送给网络中所有对此信息感兴趣的主机,不是某个主机,也不是所有主机。采用传统的单播(Unicast)技术已无法解决此类网络传输问题,而若采用广播(Broadcast)技术势必会造成巨大的网络报文,增加网络的传输负担,将会严重影响到网络的效率。而多路广播(Multicast)正是针对此类问题提出
