摘要：

An identity-based broadcast encryption protocol for ad hoc networks is proposed. Whenever a new mobile ad hoc network is formed, the proposed protocol only requires each group member to broadcast his/her identity to construct the group key, which avoids a large number of message exchanges between group members like group key management protocols proposed previously. Hence it is highly efficient in terms of member removal to construct a new network. In addition, our protocol is also efficient in computation since the encryption and the decryption only require two bilinear pair computations. Furthermore, we show that the new protocol is provably secure under the standard model.
