Based on the threshold secret sharing mechanism , a new efficient distributed group key management scheme named edgk was proposed 摘要基于门限秘密分享技术,提出一种高效的分布式组密钥管理方案edgk 。
Based on bilinear pairings and the random oracle model , a new identity - based dynamic group key agreement protocol for mobile networks was proposed 基于双线性对和随机预言模型,针对移动网络提出了一个动态群组密钥协商方案。
Because of the importance and urgency of security to multicast , this thesis investigates two key issues , i . e . authentication and group key management , of multicast security 安全是多播研究中急需解决的问题。本文对多播安全中认证和组密钥管理这两个关键问题进行了研究。
Multicast confidential is realized by sharing a group key and encrypting communication data by the group key . how to distribute , manage and update this key is key of multicast security 多播数据传输的保密性是通过所有多播组成员共享一个组密钥,组内通信通过组密钥加密实现的。
