Abstract: Embodiments of the present disclosure provide a communication method and apparatus, applied to nodes supporting short-range communication, for example, Bluetooth nodes or nodes in an in-vehicle short-range communication system. The method includes receiving an association request message from a second node and determining a group key of a first communication group. The first communication group is a communication group to which the second node belongs. The method further includes encrypting the group key of the first communication group, based on a shared key between a first node and the second node, to obtain a first protection key and sending a first association establishment message to the second node. The first association establishment message includes a first protection key.

Abstract: A security protection method and an apparatus to implement security protection for a plurality of non-access stratum (NAS) connection links. The method includes determining, by a terminal, a first parameter, where the first parameter is used to indicate an access technology used to transmit a non-access stratum NAS message. The terminal can support at least two access technologies, and can separately maintain a corresponding NAS COUNT for each of the at least two access technologies. The method further includes performing, by the terminal, security protection on the NAS message based on the first parameter, a NAS key, and a NAS COUNT corresponding to an access technology used to transmit the NAS message. This application is applicable to a process of performing security protection on a NAS message.

Abstract: The present disclosure discloses a communication method and a device. The method is performed by a target base station and includes: receiving a handover request from a source base station, where the handover request includes a first key and first indication information, and the first indication information is used to indicate whether the first key is an updated key; and sending second indication information to the source base station based on the handover request, where the second indication information is used to indicate whether an access layer key between the target base station and a terminal device is an updated key. Using the embodiments of the present disclosure helps resolve a problem that a potential security risk exists in data transmitted between the terminal device and the target base station, and helps resolve a problem that a key change of the terminal device is not controlled by the base station.
