| 摘 要： | 通常的群组密钥协商方案，一般都针对普通的、静态的群组。基于GDH的协商式虚拟动态子群组密钥管理方案实现了利用原来大群的密钥信息，有效地建立和管理虚拟动态安全子群的方法，与GDH方案相比，减少了很多的数据传输和密钥存储空间。

| Abstract: | Key agreement is usually mentioned in general static group.Based on virtual dynamic subgroup,Agreed Virtual Dynamic Subgroup Scheme (AVDSG) was proposed,which can manage the virtual dynamic subgroup by using the key information of the group.Compared with GDH,it can largely reduce the average cost of re-keying and the number of keys held by each user. |
