This letter focuses on the secure communications in integrated satellite-terrestrial backhaul networks (ISTBNs), where the base stations are capable of processing legitimate signals and transmitting the jamming signal to interfere with eavesdroppers. To this end, we exploit artificial noise (AN) to...
