Image Encryption using chaotic logistic maps with larger key
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 5
Abstract
Chaos-Based encryption technology has been studied for decades and it has become an important branch of cryptography because of its interesting features such as high security, speed, and dynamic in nature. The encryption phase works using an iterative cipher feedback mechanism combined with secret key and sequence generated by two chaotic logistic maps. After encryption of each pixel of plain-image the secret key is modified this makes the cipher more robust against any attack. The Proposed method enhances the secret key to 208-bit and analysis will be done with the existing one. Security analysis results of proposed and previous ones demonstrate the effectiveness and robustness of the efficient method among them.
