Abstract: A method for remotely managing a sensor network topology includes: receiving a device management DM command sent by a device management server, where the DM command acts on a preconstructed management object MO node and the MO node includes a node configured to discover a sensor network topology, a node configured to describe a sensor network topology, or a node configured to modify a sensor network topology; and managing a sensor network according to the DM command, where the management includes discovering the sensor network topology, describing the sensor network topology, or modifying the sensor network topology. By adopting the present invention, remote topology management of a sensor network successive to an M2M gateway can be implemented and the complexity for implementing the management is reduced.

Abstract: A method, device and system for authenticating gateway, node and server are provided in this invention. The node receives a message sent by a gateway, wherein the message comprises a number T3 shared by the gateway and a server, and a gateway identification. The node encrypts data with a key K1 shared by the node and the server, the data including T3, the gateway identification, and a random number T1 generated by the node, and then sends the encrypted data and a node identification to the server through the gateway. The node decrypts data encrypted by the server and forwarded by the gateway with the key, determines that the server is a valid server according to a T1-related number obtained by decryption, and establishes a security channel with the gateway according to a new key obtained through the decryption.
