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: A method and an apparatus for determining a security protection mode. In the method, a terminal device may determine a security protection mode of a second communications mode based on security protection information in a first communications mode. In this way, when switching from the first communications mode to the second communications mode, the terminal device may directly use the security protection mode corresponding to the second communications mode to protect transmitted data, so as to ensure data security of the terminal device after communications mode switching is performed.

Abstract: A virtual network function (VNF) audit method and apparatus, used to audit a VNF generated by a platform that includes an authentication and authorization component, a service component, and a virtualized infrastructure. The method includes receiving an event reported by the authentication and authorization component, receiving an event reported by the service component, and receiving an event reported by the virtualized infrastructure, obtaining an event occurrence sequence of each VNF according to all received events, and auditing the event occurrence sequence of each VNF to obtain an audit result of the VNF. According to the method, the events that are distributed in different components are integrated into one event occurrence sequence in order to visually and quickly detect a malicious VNF generated by bypassing a component, and more comprehensively detect the malicious VNF, thereby reducing a missed detection rate of a VNF operation audit.

Abstract: This application provides a key configuration method and an apparatus. A key management center obtains a service key, and performs encryption and/or integrity protection on the service key to obtain a token. The key management center sends the token to a first network element, the first network element forwards the token to a second network element, and the second network element obtains the service key based on the token. The service key is used to perform encryption and/or integrity protection on data transmitted between the first network element and the second network element. Therefore, security key configuration can be implemented through interaction between the key management center and the network elements, thereby laying a foundation for end-to-end security communication between the first network element and the second network element.

Abstract: A network authentication system comprises user equipment (UE), a service network (SN) and a home network (HN). The HN generates an expected user response (XRES) based on an identifier of the UE and generate an indicator, and sends the part of XRES and the indicator to the SN. The SN receives the part of XRES and indicator, and receives a user response (RES) from the UE. The SN then compares the RES with the XRES base on the indicator, and sends a confirmation message to the HN when the comparison succeeds.

Abstract: This application discloses a data flow control method and apparatus. The method includes: calculating, by a device when a clock signal arrives, a quantity of transition-minimized differential signaling (TMDS) characters currently stored in a buffer of the device; and outputting, by the device, the TMDS character in the buffer when the quantity of TMDS characters currently stored in the buffer reaches a preset value, or outputting a gap data packet when the quantity of TMDS characters currently stored in the buffer does not reach a preset value, where the preset value is less than or equal to a TMDS character storage capacity of the buffer.
