In this research note, we propose a solution to the problem of generalized group-oriented cryptography. By applying the scheme presented one can send a confidential message to a group of users such that the message can be revealed only when the specified members cooperatively work together. The organization and policy of the target group does not need to be known by the sender; only the public keys of users in the group are needed. The scheme presented is quite practical, and can be used in a large group-oriented network. © 1994.
