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.
