In this paper, we propose a group-oriented management of key trees. Traditional approach to manage key tress such as TGDH cannot retain characteristics of subgroups and it costs a great quantity of exponentiation computation to calculate the group key due to its algorithm. By means of group-oriented management of key trees, we reduce the cost of rekeying and the message size that is consultation to evaluate performance of key trees. Therefore, our approach applied to group key management not only performs well but also supplies members with more information
