%X Online/offline multi-signature schemes allowed multiple users to efficiently sign on a common message and then generated a single signature. This paper convinced the verifiers that who had signed on the message. Computed most computations before the message was given. Only small quantities of computations were needed after the message was available. Gave the formal definition of the online/offline multi-signature and the security notion. Based on the online/offline signature proposed by Guo, with the method that used by Lu et al to construct multi-signature, gave a concrete scheme. It could be proven secure in the standard model, and it was efficient.
