An Image Encryption Method Based on Tent Chaotic Map in DCT Domain

Abstract:

In recent years, the chaos based cryptographic algorithms have suggested some new and efficient ways to develop secure image encryption techniques. In this paper, the sequence was generated using chaotic system, combined with high efficiency and better security in transform domain. An image encryption method based on Tent chaotic map in DCT domain was proposed. The simulation results show that this method has characteristics such as high efficiency and good safety, and has a certain practicality and objectivity.
