Image Encryption and Privacy Protection Based on Chaotic Systems—Second Edition

Dear Colleagues,

This is the second edition of the Special Issue titled “Image Encryption and Privacy Protection Based on Chaotic Systems".

The first Special Issue of this topic collected high-quality papers, both theoretical and experiment-related ones, written by experts in this area, and it attracted a lot of interest (including numerous downloads). That is why we have decided to proceed with creating a second edition focused on this research field.

Chaos is a universal physical phenomenon in nature and the engineering world, and it is also one of the core research contents of nonlinear science. The application fields of chaotic systems are everywhere, especially in the applications of secure communication, multimedia information encryption, and the privacy protection of sensitive information. Chaotic systems have unique application advantages. They can help to carry out chaotic system modeling and can be used in dynamic complexity analysis methods to verify the chaotic behavior of nonlinear systems. Additionally, using Shannon information theory, the complexity of such systems can be studied to explain and predict their dynamic characteristics. As such, the applications of new complex chaotic systems to design high-performance image encryption algorithms and privacy protection schemes have attracted extensive attention.

Research on chaotic system modeling, complexity analysis, and security application is growing steadily; nevertheless, this field requires further exploration and innovation. New statistical techniques based on Shannon information theory, the complexity of known techniques, and a better understanding of the meaning of entropy in complex systems are needed. It is necessary to combine new computer technology and artificial intelligence methods to explore new methods for the security application of chaotic systems. Papers which focus on solving these problems are welcome to contribute to this Special Issue.

This Special Issue aims to become a forum to introduce new and improved technologies of chaotic system modeling and complexity analysis. In particular, with the help of chaotic system models, combined with new computer technology and artificial intelligence methods, proposing new image encryption algorithms and privacy protection schemes falls within the scope of this Special Issue.
