Abstract

Due to overlapping coverage areas of nodes, traditional data encryption methods for sensor networks fail to consider the logical correlation between common nodes and transmission paths, resulting in low data capture efficiency, low data communication after encryption, and poor data sensitivity extraction effect. Therefore, this paper proposes an automatic encryption method for sensor network capture data based on symmetric algorithm. Based on the analysis of WSN architecture and sensor node structure, symmetric algorithm encryption flow is designed; The network attack model is established, and the multi-path transmission security is analyzed according to the symmetric algorithm, the probability of successful eavesdropping is calculated, and the sensor network capture data is encrypted accordingly. In order to verify the performance of network capture data encryption, a comparative experiment is designed. The results show that the data recall rate is as high as 99.0%, the data communication volume can reach 6.97 × 104byte, and the extraction accuracy of sensitive information can reach 97.9%. This method can effectively solve the problems existing in traditional methods and lay a foundation for the development of sensor network data encryption.
