Security of images plays an import role in communication in current era due to the popularity and high usage of multimedia content in the Internet. Image security is described as applying an encryption algorithm over the given plaintext images to produce cipher images that can be transmitted safely over the open channel, the Internet. The problem which plagues these image ciphers is that they are too much time consuming, and that do not meet the dictates of the present times. In this paper, we aim to provide an efficient image cipher. The previous studies employed many constructs like Langton's Ant, 15 puzzle game and Castle in the 2D scrambled image based image ciphers, which had grave implications related to the high execution time of the ciphers. The current study directly made use of the 2D scrambled image to realize the purpose. Moreover, no compromise has been made over the security of the proposed image cipher. Random numbers have been generated by triggering the Intertwining Logistic Chaotic map. The cipher has been subjected to many important validation metrics like key space, information entropy, correlation coefficient, crop attack and lastly time complexity to demonstrate its immunity to the various attacks, and its real world application. In this paper, our proposed image cipher exhibits an encryption speed of 0.1797 s, which is far better than many of the existing encryption ciphers.
