RSA-based digital image encryption algorithm in wireless sensor networks

Digital Image Encryption is the image processing in the field of a new branch. This paper discusses the modern cryptography, and RSA algorithms. Root According to the data features of digital image itself, designed and implemented digital image based on RSA encryption algorithm, and made further studies of the head. The wireless sensor networks, which self-organized, are data-centered. The current urgent problem with which the wireless faced is how to protect the security of the sensor data effectively. To deal with the weakness of limitation in sensor node resources and the security threats, a novel secure transmission strategy based on information hiding for sensor data security is proposed. In ordering to protect the security of the data, we obtain the sensitive information safely to make use of the advantage of information hiding technique without encryption to safeguard the data security. The simulation experiments illustrate that it is workable to utilize the existing WSN to transmit the sensitive information covertly with the characteristics of lower energy costs and invisibility, and it is suitable for stream data in sensor nodes.
