Abstract: The range and potency of the cryptography keys are vital attributes regarding encryption and decryption. The main objective is to achieve encryption of images with the help of chaotic encryption and fractal methods. The proposed algorithm is based on the fixed point and M-J set. The fixed point is generated by using iterative method of M-J set function. Random M-J set function can be used to generate fixed point. The fixed point generated is used as encryption key. The encryption methodology is fast but a bit lossy. The images are well encrypted and the keys used for encryption and decryption are robust enough to attain strong encryption. There is infinite no of M-J set functions can be used to generate encryption key, thus, providing extra layer of security for the users. Also, since, there is infinite no of Julia sets can be produced from different complex functions, the strength of key used for encryption is extensively increased. The proposed method is an effective method to achieve the encryption of images using fractals. It provides good level of encryption without affecting the quality of images too much. It is used for protection of images against various kinds of attacks.
