Embodiment Construction

[0018] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

[0019] As can be seen from the accompanying drawings, a kind of authentication method for a sensor node of this program to access a mobile communication network is characterized in that it comprises the following steps:

[0020] 1) The sensor node sends an access request;

[0021] 2) The aggregation node sends the access request to the network side of the mobile communication network;

[0022] 3) After receiving the access request, the network side of the mobile communication network sends an access authentication message to the convergence node; the access authentication message includes the first authentication data sent by the network side of the mobile communication network. The sensor node decrypts according to its own authentication key and the first authentication data, and a...

Abstract

The invention provides a sensor node and an authentication method for a sensor node to access a mobile communication network. The sensor node comprises a sending unit, a receiving unit and an authentication unit. The authentication method for the sensor node to access the mobile communication network comprises the following steps: the sensor node issues a access request; a sink node sends the access request to the network side of the mobile communication network; the network side of the mobile communication network sends an access authentication message to the sink node after receiving the access request; the sensor node receives the access authentication message forwarded by the sink node and generates an access authentication response; the sink node sends the access authentication response to the network side of the mobile communication network; and the network side of the mobile communication network performs authentication access on the sensor node. By means of the scheme, the bidirectional authentication between the sensor node in the internet of things and the mobile network can be realized for the security authentication of the sensor node to access the mobile network, therefore, the transmission security and the data security of the internet of things users can be effectively protected, and the security protection for the mobile network is provided.

Description

technical field [0001] The invention relates to a sensor node and an authentication method for the sensor node to access a mobile communication network. Background technique [0002] In the prior art, it is known that the security issue is very important if the Internet of Things is to be applied on a large scale. Therefore, how to ensure the communication security and information security of wireless sensor network is very important. In addition to the common characteristics of Ad Hoc networks such as mobility, disconnection, and energy constraints, wireless sensor networks also have some obvious characteristics: the network scale is larger, the number of nodes is larger, and the density is higher. Ad hoc network; the network topology changes rapidly, and the network nodes are prone to failure; the sensor nodes in the network are powered by batteries, and the computing power, storage capacity and communication capacity are very limited. These characteristics make wireless...
