%X 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.
