AES WITH CHAOTIC USING CHEBYSHEV POLYNOMIAL

Abstract

All the important information is exchanged betweenfacilities using the internet and networks, all these data should besecret and secured probably, the personal information of personin each of these institutions day by day need to organized secretlyand the need of the cryptography systems is raised which can easilyencrypt the personal and critical data and it can be shared withother centers via internet without and concerns about privacy.Chaotic performance is added to different phases of AES but veryfew apply it on key generation and choosing ChebyshevPolynomial will provide a chaotic map which will led to randomstrong key. our system based on modified advanced encryptionstandard (AES) , with encryption and decryption in real timetaking to consideration the criticality of data images that beenencrypted the main encryption algorithm is the same themodification is done by replacing the key generation algorithm byChebyshev Polynomial to generate key with the required key size.
