All the important information is exchanged between facilities using the internet and networks, all these data should be secret and secured probably, the personal information of person in each of these institutions day by day need to organized secretly and the need of the cryptography systems is raised which can easily encrypt the personal and critical data and it can be shared with other centers via internet without and concerns about privacy. Chaotic performance is added to different phases of AES but very few apply it on key generation and choosing Chebyshev Polynomial will provide a chaotic map which will led to random strong key. our system based on modified advanced encryption standard (AES) , with encryption and decryption in real time taking to consideration the criticality of data images that been encrypted the main encryption algorithm is the same the modification is done by replacing the key generation algorithm by Chebyshev Polynomial to generate key with the required key size.
