In the proposed scheme, we employ polynomial function and filter functions as the basic means of constructing broadcast encryption procedure in order to reduce computation and shortage overhead. Compared with existing schemes, our scheme requires low computation, corrmaunication and storage over- heads in receivers and can support the dynamics of the privileged users. Furthermore, our scheme can avoid n^assive message to exchange for estab-fishing the decryption key between members of the cluster. The analysis of security and perforrmnce shows that our scheme is more secure than Mu- Vmdharajan's scheme and has the same speed of encryption and decryption as theirs. So our scheme is particularly suitable for the devices with low power setting such as ad hoc networks.展开更多
