With the deep penetration and iteration of network technology, the realization of secure and controlled information query is related to the confidentiality, integrity and availability of data resources. In this paper, a quantum information query scheme based on quantum teleportation is proposed by combining quantum teleportation and information query. In this scheme, the user transmits the query information while performing two-way authentication with the access controller to verify the legitimacy of the user, and then the information is sent to the data processing center using quantum teleportation and the correctness of the signature is verified, and then the system performs the retrieval operation. The scheme is characterized as follows: synchronization of authentication and encryption is achieved by integrating the authentication bits and encrypted information bits into the same quantum sequence by using bi-directional authentication in non-orthogonal states and bit-folding techniques; By implementing localized unitary operations on the shared EPR entangled states, the verification information is encoded in the quantum correlation properties between particles, forming a novel communication architecture for transmitting information through particles invisibly; The security analysis shows that the scheme is non-forgeable, non-repudiation and traceable, as well as resistant to intercept-retransmit attacks and denial-of-service (DOS) attacks.
