    Abstract

    In this digital era, the Internet is a main source of communication. Due to exponential advancement in Internet technologies, transmission of multimedia data is very common now. However, transmitting sensitive information over the Internet is always vulnerable to different kind of attacks. In order to address such issues, cryptographers are proposing encryption techniques. In encryption, data is manipulated in such a way that intruders cannot access the original information. This paper presents a secure image encryption scheme via Intertwining and Nonlinear Chaotic Maps (NCA). Both main steps i.e., confusion and diffusion are implemented using chaotic maps. Numerous security parameters are applied to the proposed improved technique and strength of the scheme is evaluated. All experimental results proved the robustness and higher security of the proposed chaos-based scheme.
