Embodiment 1

[0020] figure 1 It is a flowchart of a method for improving communication security in a sensor network provided by Embodiment 1 of the present invention. Such as figure 1 As shown, the method mainly includes the following steps:

[0021] Step 11. When the sensor nodes in the same subnet communicate, the sensor nodes of both communication parties use the pre-assigned initialization key and their own identity to perform identity authentication, and generate new information for the communication parties after the authentication is passed. The key for the sensor nodes to communicate.

[0022] In the embodiment of the present invention, when the system is initialized, the sensor nodes belonging to the same subnet are provided with the same initialization key in advance.

[0023] In the embodiment of the present invention, each aggregation node in the sensor network carries multiple leaf nodes through the RPL protocol (low power lossy network routing protocol). Each parent node ...

Abstract

The invention discloses a method for improving communication security in a sensor network. The method for improving the communication security in the sensor network includes: when communicating between sensor nodes in the same sub-network, both the sensor nodes identify the identities according to pre-distributed initial secret keys and identity marks thereof, and new secrete keys for communicating between the communicating sensor nodes are generated after passing the identification, when the sensor nodes receive new information, the sensor nodes judge that whether the information is sent from the identified sensor nodes or whether the information is the identity identifying information sent from the new sensor nodes; if not, the information is served as abnormal information, and a prestored warning mechanism is triggered. By means of the method for improving the communication security in the sensor network, the security transmission of the information in the sensor network is guaranteed.

Description

technical field [0001] The invention relates to the technical field of communication, and relates to a method for improving communication security in a sensor network. Background technique [0002] WSNs (Wireless Sensor Networks, wireless sensor network) is a network composed of a large number of low-power, low-speed, low-cost, high-density micro-nodes deployed in the monitoring area through self-organization and self-healing. This large-scale, low-cost, unattended, automatic networking, and strong invulnerability network method has broad application prospects in many monitoring fields such as ecological environment, industry, military, smart city, and smart home. [0003] 6LoWPAN is a product of the close combination of the IPv6 protocol and the wireless sensor network. The main idea is to add an adaptation layer between the IPv6 network layer and the MAC layer, so that the wireless sensor network supports IPv6 transmission. 6LoWPAN compresses the headers of the upper laye...
