An image encryption scheme based on one time pads — A chaotic approach

Due to the unlimited growth of Internet and communication technologies, the extensive use of images in diverse areas such as medical, military, science, engineering, art, entertainment, advertising, education has become unavoidable. With the increasing use of digital techniques for transmitting and storing images, the fundamental issue of protecting the confidentiality, integrity as well as the authenticity of images has become a major concern. This paper proposes a new encryption algorithm for providing confidentiality of images based on chaos theory. The experimental results of the proposed algorithm have been analyzed with benchmark images and are compared with various image encryption algorithms proposed in the literature. Key sensitivity analysis, Key space analysis and statistical analysis proves that our proposed algorithm offers improved security at a very low computational overhead.
