A security model for IPTV with one-time password and Conditional Access System for smart mobile platform

Abstract

IPTV should use an Internet protocol as well as satisfy the security requirements. However, no IPTV exhibits both of these characteristics in the present era. Usually IPTV uses Conditional Access System (CAS) and Digital Rights Management (DRM) as a means to protect the contents. However, these two approaches use different broadcasting systems and are limited for on-demand purposes. Such approaches illustrate the limited use of IPTV to date. In this paper, a more effective method to improve the security system will be proposed for smart mobile platforms. In this method, both the content server and IPTV use an OPT in order to apply a security code to the contents. In addition, the model performs CAS to manage user rights and keys. Such a method for smart mobile platforms will decrease the load between the server and the client network and secure the transfer of user certification, content security, and stream data.
