IPv6安全机制的研究

作为新版IP协议，与IPv4相比，IPv6在网络保密性、完整性方面有了更好的改进，因此，IPV6和IPV4将在过渡期内共存几年，以后IPV6渐渐取代IPV4。文中探讨了IPv6的安全特性，以及基于IPv6的验证和加密，并从IP的AH和ESP标记两方面来阐述安全机制的实现，最后，讨论了IPV6在安全方面带来的拒绝服务攻击乏力、被黑客篡改报头等新的安全问题。

Study on IPv6 Security Mechanism

As the new edition of IP agreement, IPv6 has a better improvement in network security and integrality. Thus, IPv6 and IPv4 would coexist in transition period for several years, and IPv6 could by gradually replace IPv4. This paper discusses the security features of IPv6 security mechanism, and IPv6-based verification and encryption. And the realization of security mechanism is described from IP AH and ESP labels. Finally, this paper tells of the new safety problems in IPV6 denial-of-service attack, hackers tampering on the header and so on .
