本文提出了一种可用于多用户量子数字签名的方案。该方案基于GHZ（Greenberger-Horne-Zeilinger）态的特性和受控量子隐形传态。与基于计算复杂度的数字签名方案不同，该方案是无条件安全的，并且与以前提出的量子签名方案相比，不需要仲裁者来验证签名，实现了一个消息可以由多个用户共同签名。
In this paper, a scheme which can be used in multi-user quantum digital signature is proposed. The scheme of signature and verification is based on the characters of GHZ (Greenberger-Horne-Zeilinger) states and controlled quantum teleportation. Different from the digital signatures based on computational complexity, this scheme is unconditional secure, and compared to the former presented quantum signature scheme, it does not rely on an arbitrator to verify the signature and realize a message can be signed by multi-user together.
