基于分级密钥管理的安全组播方案
A Security Multicast Scheme with the Hierarchical Group Key Management
-
摘要: 该文提出了一个新的适用于大型动态组播群组的密钥管理方案，在分级结构中采用Hash链作 为数据传递密钥来实现层与层之间的数据传递，在子组内利用数字信封来实现密钥管理。此方案具有良好的计算、存储性能及动态安全性，为进一步研究提供了一个有价值的参考。Abstract: A new key management scheme applied for large dynamic multicast group is proposed in this paper. In the hierarchical structure one-way hash chain is used as transmission key to transmit the data between the levels. Digital envelope is used to realize key management in subgroups. This scheme is of good attributes in computation, storage and dynamic security. It provides a valuable reference to further study.
