摘要： The present invention relates to mobile communications technologies, and discloses a method, device, and system for pre-authentication. A pre-authentication device receives a pre-authentication message that carries a pre-authentication option; determines a Mobile Node (MN) to be pre-authenticated according to the pre-authentication message; sends an authentication request message to an Authentication, Authorization and Accounting (AAA) server to request authentication of the MN; receives an authentication response message that is sent by the AAA server, where the authentication response message carries a pre-authentication key used between a Candidate Authenticator (CA) and the MN; and sends the pre-authentication key to the MN. Through implementation of the present invention, the pre-authentication key is obtained before the MN switches to the CA. In this way, security of communication is enhanced, and delay of switching and authentication is shortened.

摘要： A method for generating a secure association key (SAK), a method for realizing medium access control security (MACsec) and a network device are provided. The method for generating an SAK includes the following steps. A sending key selection protocol (KSP) instance sends a key selection protocol data unit (KSPDU) to the other KSP instances in the same secure connectivity association (CA). The KSPDU includes a secure connectivity association key identifier (CKI) of the instance and information about a MACsec level that the sending KSP instance belongs to. If the receiving KSP instance and the sending KSP instance belong to the CA with the same MACsec level, an SAK is generated based on the KSPDU. The MACsec of multiple levels in a communication network and the secure MACsec network communication with multiple levels are realized, thus ensuring the confidentiality of the network communication.

摘要： A method, system, and apparatus for diagnosing a route in a network based on a Diameter protocol are provided. The method includes the following steps. A source Diameter node generates a diagnosis message and sends it. An intermediate Diameter node adds diagnosis information thereof to the diagnosis message after receiving it and forwards it until the diagnosis message is forwarded to a Diameter server capable of processing the diagnosis message or a Diameter node incapable of forwarding the diagnosis message. The Diameter server or the Diameter node generates a response message and sends it carrying diagnosis information thereof, information in the diagnosis message, and a response type. The intermediate Diameter node adds the diagnosis information thereof to the response message after receiving it, and forwards it until the response message is forwarded to the source Diameter node. The source Diameter node parses the response message to obtain route related information.

摘要： A redirector, a relay, a system for configuring route information, and a method for updating route information are disclosed herein. The redirector includes: a route storing module and a route indicating module. The redirector further includes: a monitoring module which is coupled to communicate with the route storing module and configured to monitor change of the route configuration information; and a notifying module which is coupled to communicate with the monitoring module and configured to send a notification to the intermediate node managed by the redirector, where the notification indicates that the route information corresponding to the changed route configuration information is invalid. Through the foregoing solution, after the route configuration information changes, a notification may be sent in time to indicate that the previously subscribed route indication information is invalid, thus better ensuring correct forwarding of the service request message and improving the QoS.
