IMAGE ENCRYPTION FOR SECURE INTERNET TRANSFER

Abstract

Security is a crucial side to preserve the confidentiality of information such as pictures and text. The probability of an assailant attempting to access the image in the course of transferring process is high as assailant may get hold of important data. Therefore, encryption methods are used for securing the data. A novel image encryption algorithm that is a combination of the AES algorithm and the chaos sequence is proposed in this paper. The project will use AES for encryption and decryption of the image transfer because AES is capable of solving problem that cannot be resolved by different algorithms. The original image is transformed into cipher-image using a share secret key and this process is called encryption while the reverse of encryption process is known as decryption. This method’s sensitivity to the initial values and input image, even the tiniest changes within these values will result in significant changes in the encrypted image. We show that this approach can shield the image against different attacks exploitation using histogram analysis.
