Quantum Transmission Integrity Mechanism for Indirect Communication

Quantum communication networks need to securely transmit a quantum frame from source to destination. In the wireless communication network, source and destination have two types of connection: direct or indirect communication. In the direct connected mode, the transmission security can be achieved by using a quantum key distribution. In the indirect connected mode, it is a difficult problem to deal with the unsafe routing path from source to destination due to eavesdropping and man- in-the-middle attack. In this paper, we propose a quantum mechanism that designs a flexible quantum frame to achieve transmission integrity. This frame uses a quantum correlated key to let the receiver has the capability to judge whether the received quantum frame is secure or not. This mechanism provides a new solution to solve the transmission security in the unsafe routing path.
