Image Encryption Algorithm Based on Universal Modular Transformation

Xue Yang, Xiaoyang Yu, Qifeng Zou and Jiaying Jia

Image encryption is essential to assure information security. Universal modular transformation is a widely applied encryption method, but it has some disadvantages such as a relatively small quantity of keys and insecurity. A uniform block encryption method is proposed in this study to improve the image entropy of encryption and an image is encrypted with the universal modular transform combined with a chaotic mapping. Experimental results show that this algorithm can provide good encryption quality and reach high safety. Moreover, the proposed algorithm is robust to shear attack and noise attack.
