A new digital multisignature scheme shall be proposed in this paper to allow some members of a group signing the same document and sending it to the receiver, who in turn shall verify and authenticate the signature consequently. When the receiver acquires the signature, he can verify it and obtain the message by computing the signature with some public keys. With this method, the signers do not need to send the original message to the receiver, and this reduces half the communication routine for the signer and the receiver. By the way, because the receiver can get the message from the digital signature itself, we call this signature a message recovery signature.
