Abstract: This application relates to communication technologies, and provides a channel key-based encryption method and an apparatus, to resolve a problem that a terminal cannot avoid an attack from a false base station before a security mode is enabled, and a security risk. The method includes: A network device broadcasts a system information block, indicating that channel key generation is supported, where the system information block includes a preamble and a resource configuration of a physical random access channel; receives, on the physical random access channel, a first message from a user equipment, where the first message includes the preamble; sends a second message to the user equipment, where the second message includes configuration information of a first time-frequency resource; receives, on the first time-frequency resource, a third message from the user equipment; and performs channel measurement based on the third message, to obtain a channel key.

Abstract: In the communications system, a user equipment UE accesses a core network via a first network-side device by using a first air interface and connects to the first network-side device via a second network-side device by using a second air interface to access the core network. The method includes: acquiring, by the network-side device, an input parameter; calculating, by the network-side device, an access stratum root key KeNB* according to the input parameter and an access stratum root key KeNB on the first air interface, or using, by the network-side device, the KeNB as the KeNB*; and generating, by the second network-side device, an access stratum key on the second air interface according to the KeNB*, or sending, by the first network-side device, the KeNB* to the second network-side device.

Abstract: The present invention relates to a data transmission method, apparatus, and system. The method includes: obtaining, by a benefited device, a cooperative-layer key, performing encryption, or encryption and integrity protection processing on uplink data by using the cooperative-layer key at a cooperative layer to obtain first encrypted data, performing encapsulation processing on the first encrypted data to obtain first encapsulated data, and sending the first encapsulated data to a supporting device in a short-distance communication mode, so that the supporting device processes the first encapsulated data to obtain second encapsulated data and sends the second encapsulated data to a base station. In embodiments of the present invention, secure data transmission is implemented between the benefited device, the supporting device, and the base station in a cooperative communication process, which improves network security and reliability of data transmission.
