摘要
IP安全是保证Internet网络安全的重要部分。从分析IPv4各方面所面临的问题入手 ,与新一代IP协议IPv6作了比较 ,详细分析了IPv6地址空间、地址结构、扩展头、对扩展选项的支持、流标记、身份证及封装安全载荷等特点 ,可以看出IPv6有效地解决了IPv4面临的地址枯竭、路由效率低、缺少安全性及服务质量等问题。IPv6将进一步推动Internet网络的发展。
IP security is the important part of guarnteeing Internet security.Different problems of IPv4 are discussed and IPv4 is compared with IPv6.Address space,address architecture,extension headers,support of extension options,flow label,authentication head,and characteristics of encapsulation security payload of IPv6 have been analyzed in detail.IPv6 can solve the inadequate address,inefficient routing,weak security and quality of service that IPv4 has been faced.IPv6 will promote the development of Internet network further.
