摘要
En 中文
Chaotic map is widely used in various fields such as information security, information communication, and system control, etc. due to its excellent unpredictability and complexity performance. In this study, based on the published literatures, a novel 2D-ICCM (2D Infinite Collapse Coupling Map) is developed by combining two 1D-ICM (1D Infinite Collapse Map) and its chaotic performance is verified through different analyses on bifurcation characteristic, lyapunov exponent, and information entropy and through randomness test. The results obtained from experiments demonstrate that proposed 2D-ICCM has excellent chaotic behavior. In addition, in order to validate applicability of the proposed 2D chaotic map to image encryption, 2D-ICCM implemented simple-structured pixel-level image encryption algorithm is proposed and the performance of our scheme is verified through experiments. The experimental results show that the proposed image encryption algorithm is robust to various cyber-attacks and has excellent performance.
