IPv6安全機(jī)制問題探討_最終定稿
（作者未知） 2010/5/23
摘要：隨著Internet的迅速增長以及IPv4地址空間的逐漸耗盡，IPv6作為Internet協(xié)議的下一版本，正在不斷擴(kuò)大著其影響力。與IPv4相比，IPv6在地址空間和網(wǎng)絡(luò)保密性、完整性方面有了長足的進(jìn)步，因此可以預(yù)測，IPv6將在未來的幾年內(nèi)逐漸取代IPv4。本文以IPv6的定義和技術(shù)特點(diǎn)為出發(fā)點(diǎn)，詳細(xì)闡述了基于IPv6的驗(yàn)證和加密安全機(jī)制，并討論了IPv6在網(wǎng)絡(luò)安全方面引發(fā)的一些不容忽視的問題，如易受蠕蟲和病毒攻擊、拒絕服務(wù)攻擊乏力等等。最后，文章提出了可以利用現(xiàn)有技術(shù)手段來解決網(wǎng)絡(luò)安全問題的應(yīng)對措施。

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.
Key words: IPv6；security mechanisms；Network Security
