可信网络研究

Research on Trustworthy Networks

当前孤立、单一和附加的网络安全系统已经不能满足客观需求.该文在分析可信网络的产生背景和动机的基础上,提出了可信网络的概念,揭示了其基本属性,即安全性、可生存性和可控性,阐述了它们之间的紧密联系,并讨论了可信网络研究需要解决的关键科学问题.最后,介绍了国际上与此相关的研究工作.

As networks have grown in size and complexity, the existing isolated and add-on secure systems of Internet are confronting some serious challenges, with frequent failures of withstanding malicious attack, mis-malicious damage and systems fault. Trustworthy networks will be an important trend of the research on network security. In this paper, three essential properties are proposed and explained to interpret trustworthy of network, namely security, survivability and controllability. Four key issues needed to be resolved are also discussed. Finally, some current works about trustworthy networks are introduced.
