This paper proposes a distributed encryption scheme, where any party can "signcrypt" a message and distribute it to a designated group and any member in the receiving group can "de-signcrypt" the message. We also propose a group signcryption, where, given a designated group, any member in the group can signcrypt a message on the group's behalf. A group signcrypted message can be distributed to another group. The proposed schemes have potential applicability in electronic commerce.
