Image encryption with the AES algorithm in wireless sensor network

The growth of multimedia applications in wireless sensor network requires more efficient data storage and transmission techniques. In addition, when it comes to wireless sensor network, we mainly focus several constraints. Among which the materials resources where a wireless sensor network consists of several small size devices called nodes sensors. Thus, the second challenge we face is the hostile deployment environment where safety intervention is required to ensure the data transmission. In this paper, we propose a symmetric cryptographic algorithm contains simple mathematical operations that agrees with the sensor node nature and increase its lifespan. Our algorithm used to encrypt the image in real time while reducing the execution time.
