Chaos-based video encryption for network coded wireless systems

The ease of sharing information happening today increases the number of data transmissions over the Internet, which started by a simple text transmission, and evolved to more complex formats, such as image, audio and video. This data can then be easily accessed by attackers, hence the need for security. In this paper, we propose a modification to the Enhanced 1D Chaotic Key Based Encryption (ECKBA) with cat map that will be applied on video transmission (sequence of images), by changing the confusion and diffusion blocks, in order to ensure a higher level of security. Moreover, to guarantee the security for real-time applications transmitted over an unreliable network, we include a method that combines the new scheme with the Network Coding principle.
