Secure Data Transmission of Wireless Sensor Network Based on Information Hiding

Wireless sensor networks are self-organized and data-centric. Security is a critical issue in many applications. In order to protect the security of data, we propose a novel secure transmission strategy based on information hiding (IH). In this design, we acquire sensitive information securely so as to make use of the advantage of IH technique without encryption. Our approach deal with the weakness of limitation in sensor node resources and the security threats, it is suitable for stream data in sensor nodes. The simulation experiments also demonstrate that this approach is effective in transmitting sensitive data covertly with the characteristics of lower energy consumptions and invisibility.
