Abstract：When the sensor nodes in Wireless Sensor Network (WSN) are captured, the internal attack may occur, thus resulting in a security deficiency of the system information. Regarding this, a security defense mechanism based on the annular space correlation model was proposed. The combined trust value between the nodes was calculated based on the model of the annular space, and the trust assessment again on its adjacent nodes was carried out. The captured nodes were recognized according to the trust assessment, and the information of the captured nodes were removed indirectly, thus achieving information security defense. The simulation results demonstrate that the data distortion has significantly improved by the optimized mechanism. This mechanism can effectively identify and remove errors and detrimental information, which improves the security of information in the system.
