首先对量子序列多重签名方案进行了研究。该方案借鉴经典的顺序多重签名模型，采用量子纠缠交换实现消息签名及其认证，并依靠量子密钥分发和一次性填充算法来保证完美的安全性。该方案支持无限数量的签名者，并且选择贝尔态光子作为信息载体，使得签名1位信息所需的光子更少，更容易实现。
The quantum sequential multi-signature scheme is researched first.The proposed scheme refers the model of the classical sequential multi-signature,employs quantum entanglement swapping to implement the message signature and its authentication as well as relies on quantum key distribution and one-time pad algorithm to guarantee perfect security.The proposed scheme supports infinite amounts of signatories,in addition,it chooses Bell-state photons as the information carrier,which means fewer photons are need to sign one bit message and be easier to realize.
