Abstract
Lately, IPTV is in the limelight using a broadband information service to provide video content and broadcast services. Current IPTV system is combining CAS and DRM system for VOD contents to protect transmitting contents and authentication, but it has drawbacks such as system's complexity and high construction costs. Multicast DRM system emerged as a method to improve them, but, in the multicast DRM system, if the key is intercepted by a malicious user, it can be viewed by an unauthorized user of illegal broadcasting which can be a problem. In this paper, we suggest to protect content from a malicious user by applying the techniques using user authentication in the multicast DRM system.
