• Abstract:

  Due to the limitations of sensor networks in computing power and vulnerability, traditional network key distribution and management methods are not applicable. In this paper, an automatic encryption method based on symmetric algorithm is proposed. Based on the digital encryption algorithm of DES, a hybrid chaotic optimization encryption theory is proposed. Firstly, the dynamic hybrid chaotic f structure of symmetric algorithm is designed by dynamic iteration method, and then the key suitable for data encryption of sensor network is selected and managed, and the key expansion algorithm is established. Finally, the automatic encryption method of sensor network capture data is completed by combining one-dimensional logistic map with two-dimensional Henon mapping, compared with AES and RAS algorithm. The experimental results of TinyOS simulation platform show the feasibility and effectiveness of the proposed method, and show good comprehensive performance, which provides a new means for the encryption of sensor networks.
