下一代互联网的网络安全

Security of the Next Generation Internet

安全问题是下一代互联网的焦点之一。文章介绍两种路线下的安全进展:演进路线下的安全进展、从零开始路线下的安全进展。两种路线实现难易程度不同。对于演进路线,文章重点阐述现有安全技术和安全机制,并指出其不足之处;对于从零开始的路线,文章重点讨论安全需求,预测未来网络应具有的安全特征。对下一代互联网未来的安全发展,文章进行了深入思考。

Security is of paramount importance for next generation Internet. This paper introduces two approaches to security： incremental evolution and clean slate. These approaches are currently in different phases. For incremental evolution, current security technology and mechanisms are discussed as well as shortcomings. For the clean slate approach, security requirements are discussed in detail and predictions made about security features of the future Internet. Some deeper thoughts on future Internet security are offered in conclusion.
