Quantum cryptography uses quantum natures to realize unconditional security without computational hard problems, which can achieve lots of significant applications of secure communication, multiparty secure computation, E-commerce, and so on. Even it can get the free-space optical communication with quantum channel. In this paper, we firstly proposed a three-level quantum satellite communication framework that covers dozens of common solutions. Among the solutions, we select and give a quantum semi-honest and semi-quantum mutual authenticated key agreement scheme with three-particle entangled states, which can provide secure service for cross-realm traditional clients with quantum satellite and super nodes. More important, by the quantum satellite's helping, the quantum satellite and the two super nodes can authenticate each other, but the three nodes cannot get any information of the session key between the cross-realm clients. The proposed scheme has the properties of completeness, information theoretic security, nonrepudiation, and unforgeability. Its information-theoretic security is ensured by quantum indistinguishability mechanics. On the other hand, our scheme is more efficient than the similar schemes.

三级量子卫星通信框架及其应用

量子密码学利用量子特性实现了无计算难题的无条件安全,可实现安全通信、多方安全计算、电子商务等诸多重要应用。甚至可以用量子通道进行自由空间光通信。在本文中,我们首先提出了一个涵盖数十种常见解决方案的三级量子卫星通信框架。在这些解决方案中,我们选择并给出了具有三粒子纠缠态的量子半诚实和半量子相互认证的密钥协商方案,该方案可以为具有量子卫星和超级节点的跨领域传统客户提供安全服务。更重要的是,在量子卫星的帮助下,量子卫星和两个超级节点可以相互认证,但是三个节点都无法获取跨域客户端之间会话密钥的任何信息。该方案具有完备性、信息论安全性、不可否认性和不可伪造性。其信息论安全性由量子不可区分性机制确保。另一方面,我们的方案比类似的方案更有效。
