Enhanced Diffusion Encryption for Video Transmission over Mobile WiMax Networks
As a promising broadband wireless technology, WiMax has
many salient advantages over such as: high data rates, quality of
service, scalability, security, and mobility. Many sophisticated
authentication and encryption techniques have been embedded
into WiMax but it still exposes to various attacks in. In this
paper, three proposed chaos encryption techniques were
described for video transmission over Mobile WiMax as an
enhancement of multimedia security problem in Mobile WiMax
which use AES algorithm. At first, a global overview of the
technology WiMax was given to determine the disadvantages of
recently used encryption algorithm with video transmission.
Then the proposed encryption techniques were presented with its
chaos systems. Next, these proposed techniques and AES were
applied to video to compare between them. It was found that
when Henon and Baker maps are combined in one technique, it
will have high speed and more robust to statistical and
differential attacks, so we can say that this technique enhances
the diffusion properties for video encryption.
