• Diffusion properties
• Henon map
• Image encryption algorithm
• Image encryptions
• Low sensitivity
• Two-point

A fast image encryption algorithm based on Henon map is analyzed and the weaknesses of the algorithm are proposed that have a low sensitivity to the plainimage and processes pixels one by one. An improved algorithm is proposed. The improved algorithm obtains good diffusion property and high processing efficiency by changing the single-point chaining way into the two-point chaining way. Experimental results show that the new algorithm has a better performance on both security and speed.
