Abstract: A network dial-up method includes: performing a negotiation in a Point-to-Point Protocol (PPP) discovery stage for each dial-up request respectively when more than one dial-up request is received,; creating a virtual PPP interface for each dial-up request; configuring the virtual PPP interfaces; coupling the virtual PPP interfaces to a physical PPP interface, where the physical PPP interface is coupled to more than one of the virtual PPP interfaces, and the physical PPP interface performs round robin processing for the virtual PPP interfaces; and performing negotiations in a PPP session stage by way of the virtual PPP interfaces, thereby succeeding in dial-up after completing the negotiations in the PPP session stage.

Abstract translation: 网络拨号方法包括：当接收到多个拨号请求时，分别在每个拨号请求的点对点协议（PPP）发现阶段中进行协商; 为每个拨号请求创建虚拟PPP接口; 配置虚拟PPP接口; 将虚拟PPP接口连接到物理PPP接口，物理PPP接口耦合到多个虚拟PPP接口，物理PPP接口对虚拟PPP接口进行循环处理; 并通过虚拟PPP接口在PPP会话阶段进行协商，从而在完成PPP会话阶段的协商之后成功拨号。

Abstract: A certificate obtaining method, an authentication method, and a network device, where a certificate is used for permission authentication when an application APP accesses an application programming interface (API) of a controller. The certificate includes one or more of: (a) information about operation permission of the APP on N application programming interfaces APIs of the controller, (b) identifiers of L APIs that are of the N APIs and that the APP has permission to operate, or (c) identifiers of R APIs that are of the N APIs and that the APP does not have permission to operate.

Abstract: A device identifier (ID) obtaining method, a terminal, and a network device, where the method includes sending, by a terminal to a network device, a first message used to obtain a device ID, where the device ID is used to globally identify the terminal uniquely, receiving, by the terminal, an encrypted key pair sent by the network device, where the key pair includes a first public key and a first private key, receiving, by the terminal, information sent by the network device, where the information is used to identify that the first public key is the device ID of the terminal, and determining, by the terminal, that the first public key is the device ID.

Abstract: A method and an apparatus for trusted measurement, where the method includes: obtaining a first processing result by performing a first-manner processing on a code segment, and using a result obtained by performing a second-manner processing on the first processing result as a reference value; obtaining, at a first moment when the system is running, a second processing result by performing the first-manner processing on the code segment, and obtaining a first measurement value by performing the second-manner processing on the second processing result; and determining whether the first measurement value and the reference value are equal, and when the first measurement value and the reference value are equal, the system is trusted, where the code segment in the memory is a code segment that does not change with normal running of the system during one start-up and a running process of the system.

Abstract: This application relates to the field of network security technologies, and provides a method and a device for detecting a network attack. The method includes: collecting characteristic information of each of N sessions in a network, where N is an integer greater than 1; obtaining a statistical result, where the statistical result is a result obtained by collecting statistics on the characteristic information of the N sessions by using each of the N sessions as a sampling unit and by using the characteristic information as a sample value; and when a difference between the statistical result and a reference result exceeds a preset condition, determining the network is under a network attack. According to this application, a session-type network attack can be effectively detected because instead of a packet, a session is used as a sampling unit.
