An efficient solution for solving the problem in generalized group-oriented cryptography is proposed. The sender can send a secret information to a group of users such that only the specified sets of members in this group can cooperate to decipher this information. The access structure of the receiving group can be dynamically determined by the sender knowing only the public keys of the receivers. The new scheme is demonstrated to be more efficient than a recently proposed generalized group-oriented cryptosystem.
