On video stream encryption efficiency for mobile cloud system

Video streaming services over the Internet is being widely used in mobile networks. From providers' point of view, the success of such service is highly correlated with the end-user degree of satisfaction which is measured in terms of Quality of Experience QoE. In fact, most of video streaming providers are adopting adaptive streaming solution that offers a better experience to the end user since it is better to have a lower video quality instead of no video at all. Currently, service providers start to secure data transfers using encrypted stream, most importantly HTTPS, as it is one pillar of the whole experience of video stream services. In this paper, we are addressing the efficiency of video encryption schemes when facing mobile cloud system requirement without compromising the end user global experience of video services.
