Abstract:
Disclosed are a data transmission method, a relevant device and a system. The system comprises an access network device (AN) and a user equipment (UE), wherein the AN is used for receiving a basic secret key sent by a device for managing a secret key in a core network, and the basic secret key is a secret key generated by means of bidirectional authentication between the UE and the core network or a secret key derived from the secret key generated based on the bidirectional authentication; both the AN and the UE are used for processing the basic secret key according to a pre-set rule so as to generate an air interface protection secret key; the UE is also used for protecting a target field in an uplink protocol data unit (PDU) by means of the air interface protection secret key, the target field contains information used for identifying a session between the UE and a target node, and data of the session between the target node and the UE needs to pass the AN when being transmitted; and the AN is used for parsing the target field in the uplink protocol data unit by means of the air interface protection secret key.
