This paper investigates a transmission scheme for enhancing quantum\ncommunication security, aimed at improving the security of space-air-ground\nintegrated networks (SAGIN). Quantum teleportation achieves the transmission of\nquantum states through quantum channels. In simple terms, an unknown quantum\nstate at one location can be reconstructed on a particle at another location.\nBy combining classical Turbo coding with quantum Shor error-correcting codes,\nwe propose a practical solution that ensures secure information transmission\neven in the presence of errors in both classical and quantum channels. To\nprovide absolute security under SAGIN, we add a quantum secure direct\ncommunication (QSDC) protocol to the current system. Specifically, by\naccounting for the practical scenario of eavesdropping in quantum channels, the\nQSDC protocol utilizes virtual entangled pairs to detect the presence of\neavesdroppers. Consequently, the overall scheme guarantees both the reliability\nand absolute security of communication.\n
