Special Issue Information
Dear Colleagues,
Recent years have witnessed rapid progress in secure multimedia communication driven by the explosive growth of digital images in applications such as social networks, cloud storage, and intelligent surveillance. Traditional text-oriented cryptographic techniques are often not optimized for the unique characteristics of image data, including high redundancy and large data volume. Consequently, image encryption has emerged as an important research direction for protecting visual information efficiently and securely.
Chaos-based cryptography has attracted significant attention because chaotic systems exhibit properties such as sensitivity to initial conditions, pseudo-randomness, ergodicity, and complex nonlinear dynamics. These characteristics provide promising foundations for designing efficient and lightweight encryption mechanisms. Recent advances have further integrated chaos theory with modern techniques such as high-dimensional chaotic systems, DNA computing, compressive sensing, and machine learning, leading to increasingly sophisticated encryption frameworks.
Nevertheless, ensuring the practical security of these schemes remains a major challenge. Besides conventional cryptanalytic threats, implementations may also be vulnerable to attacks in the hardware domain, including side-channel attacks and fault injection attacks, which exploit information leakage from physical devices. Addressing these threats requires both rigorous theoretical analysis and secure implementation strategies.
This Special Issue aims to present recent advances in image encryption and chaotic cryptography, covering algorithm design, theoretical analysis, security evaluation, cryptanalysis, hardware security considerations, and practical applications. The goal is to promote deeper understanding and stimulate further interdisciplinary research in this evolving area.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
