A Simple Equal Key Agreement Scheme Achieving Access Control

Multicast applications in imbalanced environment require the equal computation for each mobile node. An ECC-based hierarchical key agreement scheme, ECC-GDH, is proposed in this paper. The scheme divides the responsibility of computation into each member so as to achieve the equality demand. Moreover, the scheme also achieves forward and backward secrecy. Finally, we obtain an access control model by using ECC-GDH.
