摘要
En 中文
Chaotic maps are widely being researched for application in cryptography. In this paper, a new chaotic 2-Dimensional Henon Sine Map (2D-HSM) is derived from the well-known Henon and sine maps. The resulting chaotic map's performance is demonstrated with the help of trajectory plots, bifurcation diagrams, Lyapunov exponents and Kolmogorov entropy. A novel Image Encryption Algorithm (IEA) is, then, proposed utilising the 2D-HSM to ensure the two essential characteristics of a good cryptographic system - diffusion and confusion. The IEA performs operations in two rounds for achieving a highly secure cipher-image. The simulation results and performance analysis are compared with some recently proposed cryptosystems which are also based on two dimensional chaotic maps. Simulations are carried out with the help of parameters like sensitivity to initial conditions and resistance to brute force attacks. The simulation results establish the security of the proposed 2D-HSM based IEA.
