Although the Internet community came up with a consensus that the future network should be trustworthy, the concept of 'trustworthy networks' and the ways leading us to a trustworthy network are not yet clear. This research insists that the security, controllability, manageability, and survivability should be basic properties of a trustworthy network. The key ideas and techniques involved in these properties are studied, and recent developments and progresses are surveyed. At the same time, the technical trends and challenges are briefly discussed. The network trustworthiness could and should be eventually achieved.展开更多

By analyzing the drawbacks of current TCP/IP protocol, we propose a new network architecture model LISNA. LISNA defines a kind of network architecture with mobility and trustworthiness, based upon the decoupling of end-host identity information from location information. This paper makes a brief description of the basic concepts and model structure that support network mobility and security. After introducing the key techniques in LISNA, the paper further illustrates how to promote the mobility handoff and to keep security association.展开更多
