A Chaotic Image Encryption Algorithm for Smart Phones

Abstract

At present, the conventional image encryption algorithm cannot be w ell applied to intelligent terminals of mobile internet due to their large computational cost and high storage requirements. Using the characteristics of chaotic sequence in the paper, the optimized encryption algorithm based on logistic and Tent mapping was used to achieve the optimization of the fast image encryption algorithm. The experimental results show that, this algorithm ensures the encryption effect while reducing the amount of computation required for image scrambling processing, and is suitable for encrypting image of mobile platforms.
