Advance Algorithm for Image Encryption Using Pixel Shuffling and Bb Equation

The encryption of image is difficult compare to the encryption of the text due to the high capacity. Recent methods are difficult to handle the image encryption . Recently, the use of chaotic signals for secure data transmission has shown significant growth in developing chaotic encryption algorithm. The application of the Brahmagupta–Bhaskara (BB) equation for encryption is reported in a very recent article. However, a number of chaos-based algorithms are proved to be insecure in the literature. It is also shown in the literature that the BB equation based algorithm can be broken by a low complexity known plaintext attack. Hence, in this paper, we are using pixel shuffling and then we make a new secure cryptosystem based on the BB equation and chaos is proposed for image encryption.
