中文摘要: 理性秘密共享协议是针对参与者都是理性的实际背景、基于博弈论模型而设计的秘密共享协议。作为经典密码学中的一个新兴研究方向,理性秘密共享已经引起极大的关注。本项目首次尝试将理性概念引入量子密码,以理性量子秘密共享为研究对象,希望进一步发挥量子密码的安全优势、挖掘量子技术在信息安全领域的潜力。本项目研究内容主要涉及理性量子秘密共享协议的交互方式、执行条件、性能表现等基本理论问题,包括:基于博弈论分析量子秘密共享的重构阶段,设计符合理性参与者模型的量子交互方式;为消除经典理性秘密共享执行的某些约束条件,对量子秘密分发和重构协议进行系统的研究,给出具有普适性的理性量子秘密共享协议;针对可验证功能等特殊实际需求,设计相应的安全、高效的量子解决方案。本项目的研究成果将弥补现有量子密码理论的不足,促进该领域的深入发展,并为未来可能的实际应用提供必要的理论依据。

英文摘要: Rational secret sharing protocols are proposed for the secret sharing problem in the case where all participants are rational, and some definations and models from game-theory literature are used for the purposes. As a new research area of classic cryptography, rational secret sharing has received a lot of attention. In this project, we introduces the concept of rationality into quantum cryptography for the first time and studies rational quantum secret sharing problem, hoping to give full play to security advantages of quantum cryptography and explore the potential power of quantum cryptography in information security fields. This project focuses on some fundamental theoretical issues: the interacting ways, the executive conditions,and performance of rational secret sharing protocols. It includes following contents: to analyze the reconstruction phrase of secret sharing based on game theory, and design quantum interaction for the rational participants; to design a widely-used quantum secret sharing protocol and eliminate the constraint conditions in the execution process of classical rational secret sharing by deeply research on quantum secret distribution and reconstruction protocols; to design secure and efficient quantum protocols by considering some practical needs, such as the verifiability. The results o
