Image encryption is different from text encryption due to some inherent features of image such as bulk data capacity and high correlation among pixels, which are generally difficult to handle by conventional methods. The desirable cryptographic properties of chaotic maps such as initial conditions and random-like behavior can be used to develop new encryption algorithms. The chaos – based cryptographic algorithms have suggested new ways to develop efficient image encryption schemes. The random-like nature of chaos is effectively spread into encrypted images. The proposed method transforms the statistical characteristic of original image information. So, it increases the difficulty of an unauthorized individual to break the encryption. The proposed symmetric image encryption algorithm provides an effective way for real-time applications and transmission.
