【摘要】 提出一种移动IP组播的密钥管理方案,通过将密钥更新消息的发送局部化,降低了通信开销。此外,还考虑了成员的移动性对密钥管理树的影响,并提出了一种有效的切换方案。最后对本方案进行了性能分析,分析表明,本方案具有较好的可扩展性。更多还原

【Abstract】 In this paper,we present a key management scheme that is suitable for mobile IP multicast.By localizing the delivery of rekeying messages,the communication cost is reduced.Furthermore,we consider the effect exerted by the mobility of user on the key management tree.Finally,the performance of this scheme is analyzed,showing the scheme is fairly scalable.更多还原
