Construction of Two Dimensional Cubic-Tent-Sine Map for Secure Image Transmission
A fusion two dimensional Cubic Tent Sine (CTS) map is formulated and its dynamic range is analysed. To explore its application in secure electronic data transmission, an image cipher is developed under the architecture of confusion and diffusion. A new dual form of chaos series based confusion with fast and efficient method is employed in this cipher. Chaotic key image with excellent random behaviour is utilized for diffusion phase. The proposed cryptosystem entails higher key space and single round structural design to achieve fast and efficient cipher. The random evaluation of CTS proves that the generated key series has more complicate chaotic conduct. Simulation outcomes demonstrates that the proposed cipher possesses better performance than other image ciphers. Security assessment proves the cipher strength that can resist against various attacks.
