Paper Title
Comparative Study of Distinct Chaos Based Image Encryption and Decryption Algorithms

Abstract
Data security, particularly for digital images, is essential in the rapidly expanding landscape of digital communications and internet applications. Image encryption provides a reliable way to protect image confidentiality over vulnerable public channels by transforming images into an incomprehensible form to resist unauthorized access. In this study, we compare and analyze three distinct chaos based image encryption algorithms - 6D hyperchaotic map with DNA encoding, bit level encryption using PWLCM map and image encryption using modified henon map. These algorithms are implemented and compared for various security parameters like keyspace, entropy, UACI and NPCR. The results show that the encryption schemes used in this study provide highly scrambled encrypted images that are tolerant to various security attacks.
