Two proper threshold broadcast encryption schemes are proposed for the mobile ad hoc network. The initial scheme achieves constant size private keys and O(n-t)-size ciphertexts. Under n+1-Decision Bilinear Diffie-Hellman Exponent (n+1-BDHE) assumption, it is provable security in the selective-identity model. Based on the dual system encryption, we propose our main construction. It also has constant size private keys and O(nt)- size ciphertexts. But it achieves full security under the static assumptions which are more natural than them in the existing schemes.
