摘　　要：基于不经意量子密钥分配(OQKD),提出了一种高效量子双重有序盲签名协议.消息拥有者计算经典待签名消息的Hash值,并将其编码为量子消息.把编码后的量子消息均分成两部分,分别发送给两个签名方.签名方和消息拥有者利用OQKD建立不经意的共享信息来实现签名.提出协议不需要制备任何纠缠资源,只需进行单粒子投影测量,在现有技术条件下易于实现.与现有双重盲签名协议相比,提出协议复杂度明显降低,且协议效率显著提高.Based on oblivious quantum key distribution（OQKD）, an efficient quantum double sequential blind signature protocol is proposed. The message owner computes the Hash value of a classical message to be signed and encodes the value as a quantum message. The encoded quantum messages are divided into two parts equally, and they are sent to two signatures respectively. The signer and message owner build the oblivious sharing information to implement the signature by using OQKD. The proposed protocol does not require the preparation of any entanglement resource, and it only needs to perform single-particle projective measurements,which is easy to implement under the present technology conditions. Compared with the existing double blind signature protocols, the complexity of proposed protocol reduces obviously, and its efficiency improves significantly.
