A Secure Solution for Ubiquitous Multimedia Broadcasting

Ubiquitous multimedia applications are becoming more and more popular. However, the solutions that confirm content and interaction security in these applications are still open issues because of various network convergences and device interconnections. This paper investigates a ubiquitous multimedia scheme and proposes a secure service solution. In the ubiquitous scheme, the multimedia content is encoded with scalable video coding and broadcasted via digital video broadcasting for handheld terminals (DVB-H) to mobile terminals, the access right is transmitted by global system for mobile (GSM) channel, and the media content and access right can also be transmitted from mobile terminals to home TV through WiFi based wireless local area network. The proposed secure solution supports three kinds of business models by using various content encryption modes and secure interaction protocols. The solution's security is evaluated and discussed. Since few works have been done to solve this problem, this paper is expected to attract more researchers.
