Digital signature is an important task in modern cryptography, which concerns about authenticity, integrity and non-repudiation of data on communication channel. In this paper, an arbitrated quantum digital signature scheme is proposed, in which the receiver verifies the signature with the help of an arbitrator. The most important property of the proposed scheme is that it can sign unknown quantum states. The security of the protocol relies on the quantum one-time-pad and the Greenberger-Horne-Zeilinger (GHZ) triplet particles distributed among communication entities. Security analysis shows that the proposed quantum signature is a secure scheme.
