In a well-developed digital world, security plays a key role in transmission of images. To overcome these challenges encryption and decryption techniques need to be applied. In this paper, the authors have applied the chaotic encryption and chaotic decryption on an image by doing pixel shuffling and using chaotic maps. Chaotic nature i.e., randomness property is present in both Henon map and Arnold cat map. Pseudorandom values generation plays an important key role in Henon maps and iteratively pixel shuffling is done in Arnold cat map.
