A NOVEL APPROACH FOR AES ALGORITHM IN IMAGE ENCRYPTİON

Today with the tremendous development of various technologies like multimedia, research on security is becoming more important. In providing security Cryptography places a very crucial role. Even though there are many cryptographic algorithms to provide security, they are not up to the satisfactory level of the users. So there was a need for research on inventing new algorithms or modifying existing algorithms. In this paper we proposed an enhanced AES algorithm for image encryption which can be used to encrypt using AES-128 bit key. The proposed modifications in this paper are: repositioning the image pixels to break the correlation between them, randomization of key and hiding the key value into the encrypted digital image. So the proposed method provides more security.
