Improved Mobile WiMax Image Privacy Using Novel Encryption Techniques
Mobile WiMax security standards from IEEE specify some
powerful standards-based security controls, including PKMv2
EAP-based authentication and over-the-air AES-based
encryption. But encryption technique does not guarantee a
powerful secure end-to-end image transmission, and,
consequently, WiMax presents a range of security design and
integration challenges. In this paper, two proposed chaos
encryption techniques were described for image transmission
over Mobile WiMax network as an enhancement of image
security problem in Mobile WiMax. At first, a global overview
of the Mobile WiMax security sublayer was given to determine
the disadvantages of recently used encryption technique. Then
three selected traditional techniques and our proposed encryption
techniques were presented. Next, these techniques were applied
to image to examine their robustness against cipher-image
attacks such as cropping, noising, and JPEG compression. It was
found that our techniques are more robust than AES and the
selected techniques in the presence of cipher-image attacks.
Keywords: Security Sublayer, Traditional Techniques, Proposed Techniques, and Cipher-Image Attacks.
