| 摘 要： | 介绍了基于逻辑密钥树的组播密钥管理方案,以及针对逻辑密钥树的改进方案.分析了各个方案如何从组播应用的要求和限制出发,在满足安全需求、提高服务质量的同时尽量降低开销,指出各个方案都是在安全性、服务质量和开销等3个方面的要求之间进行适当的折衷与平衡.通过对各个改进方案的出发点及其优缺点的分析,为如何根据实际情况设计适合具体组播业务的密钥管理方案提供了参考.

| Abstract: | The group key management scheme that adopts the means of logical key hierarchy(LKH) is introduced,together with several improved schemes based on LKH.According to the needs and limitations of multicast applications in the schemes,the solutions to provide reliable security and high quality service at a minimal cost are analyzed.It is concluded that all these schemes make certain compromises and balances among security,quality of service and cost.The analysis of the motivation as well as the advantages or dis... |
