摘要：
Recently, some blind quantum signature (BQS) protocols have been proposed. But the previous schemes have security and efficiency problems. Based on the entangled Greenberger-Horne-Zeilinger (GHZ) states, a new weak BQS protocol is proposed. Compared with some existing schemes, our protocol has 100% efficiency. Besides, the protocol is simple and easy to implement. The security of the protocol is guaranteed by the correlation of the GHZ particles held by each participant. In our protocol, the signatory is kept blind from the content of the message. According to the security analysis, the signatory cannot disavowal his/her signature while the signature cannot be forged by others.
