- Cryptanalysis of a New Chaotic Cryptosystem Based on Ergodicity-This paper analyzes the security of a recent cryptosystem based on the ergodicity property of chaotic maps. It is shown how to obtain the secret key using a chosen-ciphertext attack.

- Sample software that implements this procedure while searching for chaotic solutions in general 2-D quadratic maps is available in (DOS) BASIC source and executable code. Sample software that calculates the Lyapunov exponent (-0.5 to 0.5) for the Hén

- In this paper, four chaotic maps are compared and noise effects are observed on image. Firstly, we use the image encryption algorithm to convert original image to encrypted image. Now we apply noise on the encrypted image and then decrypt ciphe
