Digital multisignature is signed by multiple signers with the knowledge of multiple secret keys and can be verified based on all signers' public keys. An efficient digital multisignature scheme can combine multiple individual signatures of the same message into a single multisignature and this mu!tisignature can be verified efficiently. In this paper we describe a multisignature scheme with distinguished signing responsibilities. In this scheme each group member has distinguished signing responsibility and partial contents of the message can be verified without revealing the whole message.
