基于IPv6的网络安全体系设计

Desian of Network Security System Based on IPv6

随着Internet的迅速增长以及IPv4地址空间的逐渐耗尽,IPv6作为Internet协议的下一版本,对IPv4的取代将不可避免的成为必然。但是,由于IPv6引入了一些新的特性以及IPv4向IPv6过渡期的存在,也带来了一些安全上的新的风险和威胁,同时和传统的IPv4网络相比,一些固有的安全问题仍然没有得到很好地解决,因此,研究基于IPv6的下一代网络安全关键技术将具有重要的现实意义。本文正基于IPv6技术对网络安全体系结构进行研究。

It is an inevitable tendency that IPv6 will substitute IPv4 as the next generation Internet Protocol with rapid development of Internet and speedy exhaustion of IPv4 addresses. But security risks and threatens are also introduced with new characteristics of IPv6 and the upgrade of IPv4 to IPv6. Simultaneously,Some intrinsic safety problems are not solved completely in IPv6 networks compared with traditional IPv4 networks. On all accounts ,it is significant to study the key security technology of IPv6 based on next generation network.
