摘要
综合考虑量子制备、量子存储、量子纠缠、量子操作、签名效率等因素,提出一种基于非纠缠量子秘密共享的盲签名方案,被签名的信息既可以是经典信息也可以是量子信息。消息拥有者根据其子秘密对将要签名的消息盲化,签名者根据其子秘密对盲化后的消息进行签名。方案使用非纠缠量子实现秘密共享,验证方只有在其他两方的合作下,才能根据其子秘密实现对签名的验证。研究表明方案满足不可伪造性、不可否认性,在节省资源和提高效率等方面也有显著提高。
Considering the factors of quantum preparation, quantum memory, quantum entanglement, quantum operations, signature efficiency, etc. , a blind signature scheme based on non-entangled quantum secret sharing is presented. The information to be signed can be the classical information or the quantum information. The owner of the message blinds the message to be signed in accordance with its sub-secret, then the signer signs the blinded message according to its own sub-message. The program uses non2entangled quantum to realise secret sharing, and only by the cooperation of other two parties can the authenticator implement the authentication on signature according to its sub-secret. Studies have shown that the scheme satisfies the unforgeability and nonrepudiation, in resource saving and efficiency improvement aspects, it is has made the remarkable progress as well.
