IPv6安全机制问题探讨_最终定稿
摘要：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，正在不断扩大着其影响力。与IPv4相比，IPv6在地址空间和网络保密性、完整性方面有了长足的进步，因此可以预测，IPv6将在未来的几年内逐渐取代IPv4。本文以IPv6的定义和技术特点为出发点，详细阐述了基于IPv6的验证和加密安全机制，并讨论了IPv6在网络安全方面引发的一些不容忽视的问题，如易受蠕虫和病毒攻击、拒绝服务攻击乏力等等。最后，文章提出了可以利用现有技术手段来解决网络安全问题的应对措施。

Discussion on IPv6 security mechanisms
WANG Bao-yi HU Bin
Abstract：With the Internet’s rapid growth and the gradual depletion of IPv4 address space, IPv6 as the next version of Internet Protocol, is constantly expanding with its influence. Compared with IPv4, IPv6 has made significant progress on address space, Internet Privacy and integrity. So, it can be predicted that IPv6 will replace IPv4 gradually in the next few years. This paper began with the definition and technical features of IPv6, detailing the authentication security mechanism and encryption security based on IPv6. At the same time, the article discussed a number of issues about the security aspects of IPv6 in the network which can not be ignored, such as it is vulnerable to worms and virus attacks, it is weak to deny of service attacks and so on. Finally, the paper proposed to leverage our existing technical means to solve network security issues responses.
