    "abstract": "A quantum key distribution and identification protocol is proposed, which is\nbased on entanglement swapping. Through choosing particles by twos from the\nsequence and performing Bell measurements, two communicators can detect\neavesdropping, identify each other and obtain the secure key according to the\nmeasurement results. Because the two particles measured together are selected\nout randomly, we need neither alternative measurements nor rotation of the Bell\nstates. Furthermore, less Bell measurements are needed in our protocol than in\nthe previous similar ones.",
