IPv6隧道代理机制中的DDoS攻击安全性分析Securit

DDoS 攻击是当今IPv4 网络上最严重的威胁之一，IPv6 网络在安全性方面的设计

十分优越，但由IPv4 过渡到IPv6 网络还需要一些转换机制，本文对转换机制中存在的安全问题进行了介绍，并着重分析了Tunnel Broker（隧道代理）机制下的DDoS 攻击。

Abstract: Even now DDoS (Distributed Denial of Service) attack is still the major threat in IPv4

network.. By taking into considerations of security issue, IPv6 network is believed to be more

secure than IPv4 network.. However, to make IPv6 network coexist with current IPv4 network,

people purpose different kinds of IPv6-IPv4 transition mechanisms.In this paper, security analysis of IPv6-IPv4 transition mechanisms was performed, especially DDoS attacks on tunnel broker mechanisms.
