摘要
由于图像有数据量大、冗余度高的特性,使得图像加密不同于文本加密.混沌系统对初始条件和参数的极度敏感性,使得它广泛应用于加密研究中.首先对传统的图像加密技术进行了总结,而后综述了基于混沌系统的图像加密技术的最新进展,分析了不同加密技术的优缺点,并对混沌加密的应用前景进行了展望与分析.
Encryption of images is different from that of texts due to some intrinsic features of images such as bulk data capacity and high redundancy. Due to the properties of sensitivity to initial conditions and parameters of chaotic maps. chaosbased encryption has been widely developed. In this paper, the traditional image encryption techniques are introduced, and the development of based-chaos image encryption techniques are surveyed. The advantages and disadvantages of the corresponding technique are pointed out. Finally. the future direction in this field is discussed.
