A novel generalized group-oriented cryptosystem with authenticated sender is proposed. The proposed generalized group-oriented system integrates the design idea of authenticated encryption scheme. In the proposed system, a secret message can be addressed to a specified authorized group, and the receiving authorized group has the ability to decrypt the secret message and authenticate the sender. For achieving both privacy and integrity in data communications, the proposed generalized group-oriented system requires smaller bandwidth as compared to the previously proposed generalized group-oriented systems. The security of the proposed system is based on the difficulty of computing the discrete logarithm problem.
