STR group key management protocol can simplify key updating for its unbalanced binary-tree structure and decrease communication cost by increasing computing cost in group key management.A hybrid group key management scheme based on STR unbalanced tree was presented.It significantly decreases computation cost,and increases key updating efficiency,while maintaining the low-communication cost feature of STR protocol at the same time.
