Image Encryption Using Extended Chaotic Sequences

Chaos-based encryption appeared recently in the early 1990s as an original application of nonlinear dynamics in the chaotic regime. In this paper, an implementation of digital image encryption scheme based on the extended chaotic reported. The chaotic cryptography technique used in this paper is a key cryptography. In this algorithm, the extended chaotic sequences were generated using-rank rational Bézier curve. The proposed algorithm is described in detail, along with its security analyses and implementation. The experimental results based on the extended chaotic sequences approves the electiveness. This mixture application of extended chaotic maps shows advantage so large key space and high-level security.
