| Abstract: | This paper presents an image encryption/decryption algorithm employing two chaotic mappings. Comparing with the Logistic mapping, the two chaotic mappings are highly chaotic, and for a wide range of the parameter. The algorithm main contains two parts: the pixel-value permutation and the position permutation. The simulation results show that the algorithm is efficient, which processes the features of low computational complexity, good encryption effect, no distortion and good stableness. |
