N2 - A practical noninteractive scheme is proposed to simultaneously solve several open problems in group oriented cryptography. The sender of the information is allowed to determine the encryption/decryption keys as well as the information destination without any coordination with the receiving group. The encrypted message is broadcasted to the receiving group and the receivers may authenticate themselves for their legitimacy of the information directly from the ciphertext. The security of the scheme can be shown to be equivalent to the difficulty of solving the discrete logarithm problem.
