Energy efficient image encryption algorithm

In recent years, several encryption schemes have been proposed to protect data from unauthorized access. It is not suitable to use traditional encryption algorithms for image encryption which were proposed for textual data. The encryption schemes used for images are computationally expensive and power hungry, hence not suitable for mobile phone devices. In this paper, an image encryption scheme is proposed which includes pixels shuffling in rows and columns using two key vectors and then Zeta Function is used to further scramble the image. The proposed cipher is a hybrid model based on Rubiks Cube Principle and Zeta Function, resulting in a fast, accurate and energy efficient image encryption scheme which is one of the key requirements of low computing devices especially mobile phones.
