中文摘要: 量子秘密共享是借助量子资源实现多个用户共享经典信息或者量子信息的过程,是一种重要的量子密码协议。量子秘密共享分两类:一类是用量子方法分享经典消息,另一类是用量子方法分享量子消息(量子态)。分享经典信息的量子秘密共享更接近实际应用,研究者已经提出了许多协议,国内外多个研究小组也完成了实验验证,但是,针对这类量子秘密共享的安全性分析还比较滞后。本课题拟继续研究分享经典信息的量子秘密共享的安全性分析方法,并在此基础上设计出安全且易于实现的量子秘密共享协议。我们将首先研究不诚实参与者的截获-重发、纠缠-测量、合谋等攻击方法对量子秘密共享协议的威胁,寻求能够抵抗这些攻击的编码与变换方法、窃听检测方法;其次,在量子密钥分配协议信息论安全定义和证明方法的基础上,研究量子秘密共享协议的信息论安全定义和证明方法;最后,根据安全性分析的结果,提出安全且易于实际实现的量子秘密共享协议。

英文摘要: Quantum secret sharing(QSS), which is an important kind of quantum cryptography protocols, is aimed to sharing a secret message among multiparty, by virtue of the quantum resources. There are two kinds of quantum secret sharing: one is sharing classical messages, the other is sharing quantum messages (quantum states) using quantum technology. In comparison with QSS of quantum information, QSS of classical information is more closer to practical application. However, the security analysis for QSS of classical information is quite imperfectly. The aim of this proposal is to continue our study on security analysis method for QSS of classical information, and then to design a secure QSS protocol, which is liable to realize. Firstly, we will research on the intercept resend attack, entangle measure attack, collusion attack, and so on. At the same time, we will seek the strategies to resist these attack methods. Secondly, based on the security definition and security proof method of quantum key distribution, we will study the security definition and security proof method of QSS. Lastly, according to the findings of security analysis, we will propose secure and realizable QSS protocol.
