Abstract: A first correspondence table in a terminal device stores a correspondence between an identifier of a process running on the terminal device and an identifier of a data stream created by the process, a second correspondence table stores a second correspondence between an identifier of an application and an identifier of a process created by the application. The terminal device receives an identifier, sent by a network security device, of a first data stream. The terminal device can find, in the first correspondence table, a first record storing the identifier of the first data stream to obtain an identifier of a process. The terminal device can find in the second correspondence table, a second record storing the identifier of the process in the first record to obtain an identifier of an application from the second record. The identifier of the application is then sent to the network security device.

Abstract: The present disclosure relates to electrostatic protection terminals. One example terminal includes a target interface, a protected circuit, a protection unit, a switch unit, and a switch control unit. The protected circuit is configured to suppress an electrostatic discharge (ESD) current or an electrical overstress (EOS) current. A first end of the protection unit is electrically connected to a first pin of the target interface. A second end of the protection unit is electrically connected to a second pin of the protected circuit. The first pin is any pin of the target interface. The second pin is a pin that is in the protected circuit and that needs to be electrically connected to the first pin. The switch unit is connected to the protection unit in parallel. The switch control unit is configured to control the switch unit to be open or closed.

Abstract: The embodiments of the present invention disclose a certificate acquiring method and device. A virtualized network function manager (VNFM) receives a certificate application proxy message sent by a virtualized network function (VNF) instance. The VNFM uses the authentication information to authenticate the VNF instance, and when the authentication succeeds, sends a certificate application message to a certificate authority (CA). Then the VNFM receives a certificate issued by the CA, and sends the certificate to the VNF instance. In this way, through a trusted link between the VNFM and the certificate authority, the instantiated VNF instance applies for a certificate issued by the certificate authority, thereby effectively ensuring security of a management channel between the VNF instance and the VNFM.
