IPv6环境下电信网络安全策略研究

IPv6 Environment Telecom Network Security Strategy Research

1995年12月,IETF提出的RFC2460标准协议,标志IPv6的产生。到20世纪末,IPv6协议得到了进一步的更新和完善,一个完整的协议体系基本上形成。IPv6的产生,是对IPv4协议的升级和优化,可以说是下一代网络体系的核心。IPv6的出现,可以解决IPv4地址面临枯竭的致命缺陷,并且在地址分类、报文格式、可靠性、服务质量、移动性、寻径效率、ICMP等诸多方面进行了协议优化和更新,使之更加适应下一代网络运行的发展需要。论文通过对IPv4协议的缺陷进行分析,进而归纳出其引发的一系列安全问题,在此基础上论述了在网络安全领域IPv6较IPv4协议的优势,以及IPv6协议引入后可能带来的新的安全问题,在此基础之上提出电信网络应对IPv6的安全体系策略构建。

In December 1995, RFC2460 proposed by IETF standard protocols, symbol of IPv6.By the end of the 20th century, IPv6 got further update and perfect, basically formed a complete agreement system.IPv6, is to the IPv4 upgrade and optimization, is the core of the next generation of network system, so to speak.The emergence of IPv6, can solve the fatal flaw of IPv4 addresses are exhausted, and classification in the address, message format, reliability, quality of service, mobility, diameter on the many aspects, such as efficiency, ICMP protocol optimization and update, make it more adapt to the development of next generation network operation needs.In this article, through analysis of the defects of IPv4, which induces a series of security issues, on this basis, this paper discusses the IPv6 in the field of network security from the advantages of IPv4 and IPv6 after introducing may bring new security issues, on this basis puts forward telecom network construction strategy to IPv6 security system.
