【摘要】 Internet网络安全问题随着Internet的日益发展而越来越被受到重视。由于许多组成Internet基础部分的早期网络协议没有充分考虑安全问题,导致其现在处于易受攻击的状态。黑客们不断地展开越来越狡猾、越来越复杂的攻击,使维护网络安全成为一种旷日持久的战斗。IPv6的出现虽然主要是为了解决IPv4地址空间有限的问题,但同时也为提高网络安全性能从协议基础上提供了支持。更多还原

【Abstract】 Internet security has been a major concern with the development of Internet.Many early network protocols that now form part of the Internet infrastructure was designed without security in mind,and hackers are continuously deploying more and more sophisticated and complex methods of attack.While the main reason for developing the new IPv6 protocol is the limited addressing available in IPv4,along with it comes an opportunity to make the TCP/IP stack more secure against the present vulnerabilities of IPv4.更多还原
