A Non Linear Equation Based Cryptosystem for Image Encryption and Decryption

The field of encryption is becoming very important in the present era in which information security is concern. Security is most important issue in communication and storage of images, and encryption is one of the way to ensure security. Image encryption has wide applications in internet communication, multimedia systems, medical imaging, military communication. Image encryption and decryption using chaotic map and a non linear equation which is known as BB equation.
