Summary 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.
