Abstract: A security implementation method, a related apparatus, and a system, where the method includes receiving, by a first network element, a request for handing over a user equipment from a source access network device to a target access network device to perform communication. The method further includes: obtaining, by the first network element, a security key, where the security key is used for protecting the communication between the user equipment and the target access network device after the user equipment is handed over from the source access network device to the target access network device; and sending, by the first network element, the security key to the target access network device.

Abstract: Embodiments of this application provide a key generation method, applied to a scenario in which a base station is divided into a centralized unit and a distributed unit and a control plane and a user plane of the centralized unit are separated. And the control plane entity of the centralized unit obtains a root key, generates a user plane security key based on the root key, and sends the first user plane security key to the user plane entity of the first centralized unit. According to this application, key isolation between different user plane entities is implemented. Further, in an actual operation, the control plane entity or the user plane entity of the centralized unit may be flexibly selected to generate the user plane security key.

Abstract: An authorization method and a network element are disclosed, to implement a third-party authorization function based on a 5G service-based network architecture. The method is: receiving, by a resource control network element, a resource usage request message sent by a terminal device; replacing a first user identifier in the resource usage request message with a second user identifier; sending an authorization request message carrying the second user identifier to an authorization server by using an NEF; receiving, by using the NEF, an authorization response message sent by the authorization server, where the authorization response message includes an authorization result that is obtained by performing authorization based on the second user identifier and the resource usage request message; and allocating a network resource to the terminal device based on the authorization result, and sending a resource allocation response message to the terminal device.
