| 摘 要： | IPv6 因其巨大的地址空间和内嵌的安全机制,已经开始逐步取代 IPv4 成为下一代互联网的标准网络协议。本文首先简要介绍了 IPv6 相比 IPv4 具有的优势,IPv6 自身的安全机制以及 IPv4 向 IPv6 过渡的主要技术。其次重点探讨了 IPv6 网络中存在的安全隐患以及相应的安全对策,主要针对协议过渡技术,IPv6 协议自身,移动 IPv6 存在的隐患,以及 IPv6 对现有安全体系的挑战进行了分析,并提出了相应的安全建议。最后对 IPv6 的应用前景进行了总结和展望。

| Abstract: | Due to huge address space and embedded security mechanisms of IPv6, IPv4 has been gradually replaced by IPv6 which is regarrded as the standard network protocol for the next-generation Internet. In this paper, the advantages that IPv6 has over IPv4, IPv6's own security mechanism and the main technologies of IPv4 to IPv6 transition are briefly introduced. The potential security risks in IPv6 network that mainly include the security risks of protocol transition technology, IPv6 protocol and mobile IPv6, as well as Pv6's challenge to the existing security system have been discussed, and the corresponding security measures are suggested. Finally, the summary and outlook of application prospects of IPv6 are illustrated. |
