Survey on Image Encryption Techniques using Chaotic Maps in Spatial, Transform and Spatiotemporal Domains

Research output: Contribution to journalArticlepeer-review

Abstract

Chaos-based cryptosystems have been an active area of research in recent years. Although these algorithms are not standardized like AES, DES, RSA etc., chaos based cryptosystems like Chebyshev polynomials can provide additional security when used with standard public key cryptosystems like RSA and El-gamal. Standard encryption algorithms such as AES have always been the primary choice, but when it comes to image or video encryption, many researchers recommend chaos-based encryption techniques due their computational efficiency. This paper presents a survey on the most up-to-date chaos-based image encryption techniques, and classifies them into spatial, temporal, and spatiotemporal domains for better understanding. The significant improvements in the field of image encryption are discussed. In addition, comparative analysis is performed to validate the evaluation matrices for quantifying the encryption algorithms' security and performance in recent papers.
