可信网络可生存性增强技术研究概述

互联网在日益成为人们日常生活中不可或缺的组成部分的同时，也日益暴露出其设计思路与当前人们对网络的需求不符合的弊端，未来网络应该是可信的，这一观点已成为业界共识。本文首先对网络可信性的内涵进行了分析，认为可信网络应该至少具有安全性、可控性和可生存性三个基本属性。然后，阐述了可信网络可生存性的概念以及可生存系统的设计模式和开发方法，并重点介绍了增强网络可生存性相关技术。

The Research Summarization of Trustworthy Network Survivability Enhancement Technology

The Internet plays increasingly important roles in everyone＇ s life, but the existence of a mismatch between the basic architectural idea beneath the Internet and the emerging requirements for it is becoming more and more obvious. The Internet community came up with a consensus that the next generation Internet should be trustworthy. In this paper, firstly, the connotation of network trustworthiness is analyzed. This research insists that the security, controllability and survivability should be basic properties of a trustworthy network. Secondly, this paper introduces the concept of network survivability, the design mode, the development method of survivable network systems and some technologies of enhancing network survivability.
